20090033510
The present invention relates to an information storage device, an information storage program, and an information storage method for collecting and storing information detected by sensors, and a verification device for verifying the correctness of the information.
The present invention relates to, for example, an information storage device for collecting and storing moving object information related to moving status of a moving object.
Further, the present invention relates to an environment information storage device for collecting and storing environment information, that is, information related to environment such as temperature, humidity, illuminance, time, location, tilt, weight, yawing, sound, wind force, impurity rate, opening/closing of a door or a cover, etc. of the transportation or storage of an object such as food (vegetables, fish, wine, etc.), animals (a racehorse or a fighting dog, etc.), breakables, medicals, photos, arts, antiques, official documents (paper documents or testament, etc.), garbage, etc. and an environment information guaranteeing system for processing these information.
(1) Conventionally, amount of automobile tax has been determined based on a type, a use, engine displacement, etc. Recently, the amount of automobile tax is changed according to performance of emission gas or fuel cost. This is not determined by driving status, but it can be said it is determined by the specification of an automobile used. For example, if an automobile is good fuel cost performance, the automobile tax is favorable even if a driver does aggressive driving such as sudden starting, sudden stopping, etc.
(2) Further, automobile insurance is also determined by a type and a use, an age of a driver, traffic accident history, a travel distance, etc. of an automobile. In the case of automobile insurance, insurance premium may be low when a driver has not caused any traffic accident even if the driver drives aggressively; a method for calculating insurance premium does not match the driving status showing how the driver actually drives.
To solve the above, there are some inventions provided.
JP2004-145489 (Patent Document 1) discloses a system related to a method for determining automobile insurance premium. In the system disclosed by the above Patent Document 1, it is assumed that a traffic accident rate is low in the case of a highly safe automobile of which tire pressure, etc. is frequently managed or an owner of the automobile, so that the insurance premium is reduced. Namely, the system includes an in-vehicle device having a vehicle status analyzing unit obtaining time-sequential information related to tire pressure of an automobile and a communication device to send the information obtained by the vehicle status analyzing unit to the outside, and a central unit having a vehicle management status diagnosing unit evaluating tire pressure management status of the automobile based on the received information and an insurance premium calculating unit calculating insurance premium and/or insurance of the automobile insurance based on an evaluated result by the vehicle management status diagnosing unit. By this, information such as tire pressure, etc. is sent to a server of an insurance company through the Internet, the vehicle management status is diagnosed based on the received information, and the insurance premium is calculated such that the insurance premium is reduced for an owner of the automobile of which traffic accident rate is low.
Further, JP2002-279298 (Patent Document 2) shows a method, as a business method based on vehicle history information, to record vehicle history information such as driving history or maintenance history of a vehicle together with personal information in a storage medium provided at the vehicle and to set insurance premium using this information at the time of automobile inspection/maintenance, or contracting/updating an insurance policy. This document describes an example of using storage medium having a data protecting function which disables a user side to tamper with driving history of an automobile which is processed by an in-vehicle management computer from various sensor information.
Further, JP2002-183456 (Patent Document 3) discloses an example of protecting by encryption or password in order to prevent people outside the insurance company from decoding the contents of the record, that is, to maintain the confidentiality of the contents of the record in a driving evaluation device calculating driving evaluation result based on driving status information of an automobile obtained, position information by GPS (Global Positioning System), map information, traffic regulation information and recording the calculated result.
However, according to the conventional system, an owner of the automobile can modify the in-vehicle device and send fake information to an insurance company. Namely, there is a problem that it is possible to get low insurance premium by pretending to frequently manage air pressure of a tire, etc., though the owner actually does not, or by sending information of another automobile.
Further, information may be tampered during communication, that is, the integrity of the information cannot be maintained, and thus there is another problem that the reliability may lack, that is, the information actually used by the insurance company cannot be reliable.
Further, there is another problem that it is impossible for the insurance company, etc. to detect tampering with the received information when the information is tampered during communication or when the information recorded in the in-vehicle device is tampered. This problem occurs regardless of encryption of the information. Namely, although the encryption can maintain the confidentiality of the information, the integrity cannot be maintained, since the tampering cannot be detected.
(3) Further, conventionally, a requesting person who requests transportation or storage of an object (a requesting person, hereinafter) trusts a dealer to carry out transportation or storage (a dealer, hereinafter) and requests the transportation or storage. For example, when fresh fish is transported from the fish market to a marketplace, a requesting person who requests the transportation at the fish market cannot know the environment of fish during the transportation, that is, if the temperature, humidity, etc. are kept so as to keep the fresh status. Further, a person who receives an object such as a restaurant which uses fish (a user, hereinafter) cannot confirm the fresh status of the transported fish, either, but the fresh status is grasped by confirming with eye-observation based on experience.
Further, in the case of storing an object in a rental warehouse, a user (sometimes the same as a requesting person) estimates the status of the object during the storage by measuring or comparing the statuses at the time of putting in/out the object to be stored.
Further, JP11-348647 related to a driving management device of an insulated truck describes an invention to reduce the load of the driver by sending/managing temperature information detected by a temperature sensor in the insulated truck to an office from the vehicle, and further describes that the information of the temperature sensor is recorded in a memory card provided at the vehicle, which enables to certify afterwards the record during the driving.
According to conventional arts, there is no way for a requesting person or a user but to trust the dealer concerning the environment during the transportation or storage, and it is difficult to confirm the transportation environment or the storage environment. Further, there is a problem that the dealer can tamper with the environment information recorded in recording medium such as a memory card and submit tampered fake information which is convenient to the dealer to the requesting person or the user, which makes the information appear to have no problem.

Referring to
(1) The moving object information storage device 3 is equipped in a moving object 1 which is an equipped moving object as shown in
(2) The moving object information storage device 3 inputs and stores each moving object information detected by each sensor of a group of sensors 2 composed of a plurality of sensors. The group of sensors 2 includes a sensor 2a, a sensor 2b, a sensor 2c, etc as discussed below.
(3) The moving object information storage device 3 generates “integrity information” discussed later based on the stored moving object information and unique information discussed later, and sends “the integrity information”, “the moving object information” and “the unique information” to a moving object information verification device 600 placed at a service center of an insurance company through public line, for example.
(4) The moving object information verification device 600 verifies the correctness of “the moving object information” based on “the integrity information” received.
In
The sensors 2a, etc. are provided at the moving object 1 and detect “the moving object information” showing moving conditions and moving status such as velocity, travel distance, the number of revolutions of an engine, location by GPS, gyro, air pressure of a tire or a passenger cabin, intervehicle distance, yawing, altitude, tilt, steering (rudder angle), temperature, humidity, etc. of the moving object 1. The twentieth embodiment which will be discussed later shows another example in which the moving object information storage device 3 has a built-in sensor.
According to the first embodiment, the sensors 2a, etc. can calculate information detected by the sensors themselves and output the calculated result to the moving object information storage device 3 as the moving object information. The moving object information obtained by such calculated result includes, for example, an acceleration, a degree of elevation, racing of an accelerator, a distance and time of meandering driving, the number of harsh breakings, the number of sudden startings, video information of inside/outside of the automobile, etc.
The second embodiment will discuss another case in which the sensors 2a, etc. do not calculate the information detected by themselves, but the moving object information storage device 3 calculates. Although in the second embodiment discussed below, the calculated result by the device-side operating unit 201 of the moving object information storage device 3 is stored as “the moving object information”, the information detected by the sensors themselves is also “the moving object information”. Like this, in this specification, “the moving object information” includes both the information detected by the sensors themselves and the result of processing the information detected by the sensors themselves (the calculated result). Namely, “the moving object information (sensor information)” is the information based on the information detected by the sensors detecting information related to the moving object. Here “based on” means to include both the information detected by the sensors themselves and the calculated result of the information as discussed above.
The moving object information storage device 3 (an information storage device) includes a storage unit 21 storing moving object information, a control unit 22, and tamper preventing unit 20 (a tamper verifying information generating unit). The storage unit 21 includes a device-side unique information storage unit 31 (a device-side specifying information storage unit), and a moving object information storage unit 32 (a sensor information storage unit), and an integrity information storage unit 33 (a tamper verifying information storage unit). Although in
The device-side unique information storage unit 31 stores “device-side unique information (device-side specifying information)” discussed later. The moving object information storage unit 32 stores “the moving object information”. The integrity information storage unit 33 stores “integrity information” discussed later.
The tamper preventing unit 20 generates “the integrity information” based on “the device-side unique information” stored in the device-side unique information storage unit 31 and “the moving object information” recorded in the moving object information storage unit 32 to prove the integrity of these information.
A control unit 22 controls these operation.
Next, the operation of the moving object information storage device 3 will be explained by referring to
(1) The moving object information storage device 3 starts recording of moving object information detected by the sensors 2a, etc. (S101) at a necessary timing. This timing can be starting an engine in the cases of an automobile or a motorcycle, etc. and when the power turns to ON in the cases of a jet-coaster (registered trademark), etc. These are determined by a service provider.
(2) The control unit 22 inputs the moving object information detected by all of the sensors 2a, etc. that are connected to. The control unit 22 stores the moving object information in the moving object information storage unit 32 (S102).
(3) And, at the necessary timing, by command from the control unit 22, the tamper preventing unit 20 generates “the integrity information” based on “the device-side unique information” stored in the device-side unique information storage unit 31 and “the moving object information” stored in the moving object information storage unit 32 (S103). Here, “the device-side unique information” is information which can specify “an appointed moving object” that is a moving object which is previously appointed to equip the moving object information storage device 3. “The device-side unique information” is, concretely, if “the appointed moving object” is an automobile, information which can uniquely distinguish the appointed moving object such as license plate information, a vehicle identification number, a production number, etc.
(4) Further, “the integrity information (tamper verifying information)” means information to confirm that “the moving object information” and “the device-side unique information” are not tampered. Namely, “the integrity information” is information used for verifying if at least either “the device-side unique information” or “the moving object information” is tampered or not. For example, a digital signature is such information. Concrete examples of generation of “the integrity information” will be described in detail in the sixth embodiment which is a system including a moving object information verification device 600.
(5) “The integrity information” generated is stored in the integrity information storage unit 33 by the control unit 22 according to necessity. On recording “the integrity information”, the control unit 22 can manage correspondence relation between “the integrity information” and “the moving object information” which is a base for generating the integrity information. By managing the correspondence relation, the correspondence relation becomes clear between “the moving object information” and “the integrity information” (S104).
(6)
(7) Timings for generating “the integrity information” depends on what this first embodiment is applied to, and can be, for example, when “the moving object information” for which “the integrity information” has not been generated at the time of starting an engine is included in the moving object information storage unit 32, when “the moving object information” is outputted to the outside of the moving object information storage device 3, when “the moving object information” is inputted to the moving object information storage device 3, when an accident or a problem occurs in the moving object 1, and so on.
As discussed above, since inside the moving object information storage device 3, the tamper preventing unit 20 generates “the integrity information” to prove the integrity of “the moving object information” and “the device-side unique information”, the correspondence between the moving object 1 and “the moving object information” is made clear, which enables to provide a service provider with the moving object information storage device 3 that stores highly reliable “moving object information”.
In the following, the second embodiment will be explained by referring to
The device-side operating unit 201 includes a function to calculate information detected by the group of sensors 2 connected. In such a configuration, the information detected by the sensor 2 is calculated by the device-side operating unit 201, and the calculated result is stored in the storage unit 21 as “the moving object information”.
The information obtained from such calculated result is, for example, an acceleration, a degree of elevation, racing of an accelerator, a distance and a time of meandering driving, the number of harsh breakings, the number of sudden startings, video information inside/outside of the automobile, etc.
For example, an acceleration can be obtained by calculating signals of a velocity sensor. Because of this, an acceleration sensor becomes unnecessary. Therefore, the embodiment has an effect that there is no need to add a sensor if such sensor is substituted by calculation of the signals detected by the group of sensors 2.
In the following, the third embodiment will be explained by referring to
(1. Special Screw)
Use of a special screw can be noted as one example of the separation preventing means.
(2. Separation Preventing Seal)
Another separation preventing means will be explained.
(3. Lockup)
Another separation preventing means, though not illustrated, can be implemented by simultaneously locking up both of the moving object information storage device 3 and the moving object 1 using a physical lock or by fixing the moving object information storage device 3 to the moving object 1 using a physical lock.
(4. Electrical Separation Prevention)
Further, an electrically implemented example will be explained as another separation preventing means.
The moving object 1 includes a moving-object-side unique information processing unit 301 (an example of a moving-object-side authenticating unit). The moving-object-side unique information processing unit 301 includes a moving-object-side unique information storage unit 311. The moving-object-side unique information storage unit 311 stores moving-object-side unique information (moving-object-side specifying information). “The moving-object-side unique information” is information kept by the moving object 1 and information which can specify the moving object 1. “The moving-object-side unique information” means, if the moving object 1 is an automobile, information which can uniquely distinguish the moving object 1 such as license plate information, a vehicle identification number, a production number, etc.
The moving-object-side unique information processing unit 301 carries out authentication process with the separation preventing unit 302. In
Next, the operation will be explained using
(1) The moving-object-side unique information processing unit 301 stores “the moving-object-side unique information” of the moving object 1 in the moving-object-side unique information storage unit 311. This “moving-object-side unique information” must have identity with the device-side unique information stored in the device-side unique information storage unit 31 of the moving object information storage device 3 if the moving object 1 is the appointed moving object. Here, the identity does not mean to have to be identical but means to be able to specify the identical moving object.
(2) The separation preventing unit 302 communicates with the moving-object-side unique information processing unit 301 at a necessary timing and obtains “the moving-object-side unique information” kept by the moving object 1 (S1).
(3) Then, the separation preventing unit 302 compares “the moving-object-side unique information” obtained and “the device-side unique information” maintained in the device-side unique information storage unit 31 (S2).
(3) It finishes normally if the compared result shows identical (S3), and the contents which has been finished normally is recorded in, for example, the storage unit 21. It finishes abnormally if the compared result shows not identical (S4), and that it finishes abnormally is recorded in, for example, the storage unit 21.
Here, timing when the separation preventing unit 302 communicates with the moving-object-side unique information processing unit 301 are at the time of starting the engine, generating “the integrity information”, with a predetermined or random interval, etc. By this, it is possible to detect that the moving object information storage device 3 is removed from the moving object 1 and is equipped in another moving object. Therefore, notifying the user that this function is mounted on the moving object information storage device 3 prevents a trial to remove the moving object information storage device 3 from the moving object.
Next, by referring to
(1) The separation preventing unit 302 of the moving object information storage device 3 generates a random number (R) (S6), and sends to the moving-object-side unique information processing unit 301 of the moving object 1 (an example of authentication request) (S7).
(2) The moving-object-side unique information processing unit 301 receives the random number (R) (S8), and after encrypting (e(R)) (S9), sends to the moving object information storage device 3 (S10).
(3) The separation preventing unit 302 of the moving object information storage device 3 receives response data (e(R′)) (S11), decrypts it (S12), and compares with the random number generated previously (S13).
(4) By the compared result, the separation preventing unit 302 judges if the moving object 1 which is the equipped moving object is an appointed moving object or not. If the compared result shows matched, the separation preventing unit 302 judges the moving object 1 as the appointed moving object; if the compared result shows mismatched, the moving object 1 is judged not to be the appointed moving object.
(5) If the compared result shows matched (S14), the process finishes normally; if mismatched (S15), the process finishes abnormally.
Next case is considered as “the predefined rule”. In the case of
Next case is considered as “the predefined rule”. In the case of
“The predefined rule” can be implemented by combining with a method to confirm the unique information explained in the above discussed
By “the predefined rule” discussed above, the separation preventing unit 302 can detect that the moving object information storage device 3 is separated from the moving object 1 and equipped in a different moving object. Further, by performing encryption, it is possible to accomplish a more reliable moving object information storage device 3 than the above-discussed confirmation of the moving-object-side unique information and the device-side unique information. Notifying the user that this function is mounted on the moving object information storage device 3 prevents a trial to remove the moving object information storage device 3.
As has been discussed, by providing the separation preventing unit 302 at the moving object information storage device 3, the correspondence relation between the moving object information storage device 3 and the moving object 1 is made clear, which prevents equipping the moving object information storage device 3 in another moving object to collect false “moving object information”. Therefore, it is possible to provide a service provider with a highly reliable moving object information storage device 3. Further, by configuring to provide the service provider with the device-side unique information maintained by the moving object information storage device 3, the obtained moving-object-side unique information of another moving object, and information showing that the moving object information storage device 3 is equipped in another moving object, it is possible for the service provider to warn the user based on these information.
In the following, the fourth embodiment will be explained by referring to
In
The separation preventing unit 302 of
That is, the moving object information storage device 3 is provided with the buttery 401 (power source) supplying electric power. The buttery 401 is not limited to be included in the separation preventing unit 302 as written above, but it is enough to be included in the moving object information storage device 3. Even if separated, by supplying electric power from the buttery 401 (power source), the separation preventing unit 302 sends “a transmission requesting signal” requesting transmission of the moving-object-side unique information to the moving-object-side unique information processing unit 301 of the moving object to have a response, or sends “an authentication start requesting signal” requesting start of authentication process to have a response. “The transmission requesting signal” or “the authentication start requesting signal” which are sent by the separation preventing unit 302 function as “a separation confirming signal” confirming that the moving object information storage device 3 is equipped in the moving object or not, namely, separated from the moving object or not. The moving-object-side unique information processing unit 301 of the moving object functions as “a responding unit” responding to “the separation confirming signal”. Like this, the separation preventing unit 302 asks the moving-object-side unique information processing unit 301 to respond by sending “the separation confirming signal” to the moving-object-side unique information processing unit 301 (responding unit), and if no response is received, judges that it is separated from the moving object.
Next, by referring to
The separation preventing unit 302 feeds electric current to the signal line 402 using the buttery 401 as the power source. When the moving object information storage device 3 is equipped in the moving object 1, electric current runs through the signal line 402. However, when the moving object information storage device 3 is separated from the moving object 1, the signal line 402 is blocked. Therefore, the electric current does not run. Namely, by observing the electric current running through the signal line 402, it is possible for the separation preventing unit 302 to detect that the moving object information storage device 3 is separated from the moving object 1.
As discussed above, by providing the buttery 401 at the moving object information storage device 3, it is possible to correctly detect the fact that the moving object information storage device 3 is separated from the moving object 1. Because of this, it is also possible to provide a highly reliable moving object information storage device 3 to the service provider. Further, it is configured so as to provide the device-side unique information maintained by the moving object information storage device 3, the moving-object-side unique information obtained from the moving object, and the information that the moving object information storage device 3 is separated from the moving object 1 to the service provider, which enables the service provider to warn the user based on these information.
In the following, the fifth embodiment will be explained by referring to
As shown in
In the above configuration, the separation preventing unit 302 detects the separation by the obtainment of the moving-object-side unique information of the moving object 1 shown in
As discussed above, when the moving object information storage device 3 is separated from the moving object, the information deleting unit 501 deletes the information in the storage unit 21. Consequently, the service provider certainly knows the separation, and the service provider can warn the user based on the information. Therefore, it is possible to provide a highly reliable moving information storage device 3 to the service provider.
In the following, the sixth embodiment will be explained by referring to
The moving object information verification device 600 includes a verifying unit 601.
Next, the operation of the moving object information guaranteeing system according to the sixth embodiment will be explained by referring to
The operation of the moving object information storage device 3 is the same as the one of the first embodiment. Namely, the moving object information storage device 3 maintains “the moving object information” and generates “the integrity information”. Further, the verifying unit 601 of the moving object information verification device 600 confirms that “the moving object information” is not tampered using “the integrity information”.
Here, it is assumed that the information is exchanged between the moving object information storage device 3 and the moving object information verification device 600 using “communication” which will be described later in the eighth embodiment or “an IC card” which will be described later in the tenth embodiment.
(1) Tamper preventing unit 20 inputs “moving object information” and “device-side unique information” to a hash function to obtain a hash value (S40). Then, “the integrity information” is generated by encrypting the hash value using a signature key (S41). The signature key is stored in the storage unit 21 of the moving object information storage device 3 beforehand.
(2) The verifying unit 601 obtains the hash value from “the moving object information” and “the device-side unique information” similarly to the tamper preventing unit 20 (S42).
(3) On the other hand, “the integrity information” is decrypts using a verification key (S43), and the above hash value and the hash value which is a result of decryption are compared (S44).
(4) As a result of the comparison, if the hash values are the same, the verifying unit 601 judges that “the moving object information” is correct information, namely, it is not tampered. If the hash values are different, the verifying unit 601 judges at least either “the moving object information” or “the device-side unique information” is tampered.
In
In
As discussed above, it is possible to verify that “moving object information” and “device-side unique information” (or the moving-object-side unique information) is not tampered, which enables to provide a highly reliable moving object information verification device 600 and a highly reliable moving object information guaranteeing system to the service provider.
Here, although
In the following, the seventh embodiment will be explained by referring to
In
Next, the operation will be explained.
(1) The operation of the moving object information storage device 3 is similar to the first embodiment or the sixth embodiment. Namely, the moving object information storage device 3 maintains “the moving object information” and generates “the integrity information”.
(2) Further, by, for example, the method shown in the sixth embodiment, the service provider confirms that “the moving object information” and “the device-side unique information” are not tampered using “the integrity information” in the verifying unit 601 of the moving object information verification device.
(3) Then, if these information are not tampered, the processing unit 701 processes “the moving object information” and “the device-side unique information”. This “process” is considered to be to determine an insurance premium, determine an automobile tax, or to detect traffic violation at the police station, etc based on “the moving object information” and “the device-side unique information”.
As discussed above, since the moving object information verification device 600 includes the processing unit 701, after verifying that “the moving object information” and “the device-side unique information” (or “moving-object-side unique information”) are not tampered, it is possible to determine a service for the user by reflecting the verified result. Therefore, the service provider can provide detailed service to the user using a highly reliable moving information guaranteeing system.
In the following, the eighth embodiment will be explained by referring to
Next, the operation of the moving object information guaranteeing system according to the eighth embodiment will be explained by referring to
(1) The moving object information verification device 600 (the service provider) stores a signature key in the moving object information storage device 3 and maintains a verification key (S30).
(2) The moving object information storage unit 32 of the moving object information storage device 3 records “the moving object information” (S31).
(3) Further, the tamper preventing unit 20 of the moving object information storage device 3 generates “the integrity information” using the signature key at a necessary timing (S32).
(4) Then, the control unit 22 sends “the moving object information”, “the device-side unique information”, and “the integrity information” to the moving object information verification device 600 (the service provider) via the storage-side communicating unit 801 (S33).
(5) The moving object information verification device 600 of the service provider receives “the moving object information”, “the device-side unique information”, and “the integrity information” by the verification-side communicating unit 802 (S34).
(6) The verifying unit 601 verifies using the verification key (S35), and then
(7) the processing unit 701 processes “the moving object information” and “the device-side unique information” (S36).
(8) Here, although in the example of
As discussed above, “the moving object information”, “the moving object unique information”, and “the integrity information” are sent to the moving object information verification device 600 by the storage-side communicating unit 801, and the service to the user can be determined after verifying that no tampering is done, so that the service provider can provide detailed service to the user using a highly reliable moving object information guaranteeing system.
In the following, the ninth embodiment will be explained by referring to
The communicating partner authenticating unit 901 authenticates a sending destination (an outputting destination) when “the moving object information”, “the device-side unique information”, and “the integrity information” are outputted.
Next, the operation will be explained. The operation of the moving object information storage device 3 is the same as the one of the first embodiment or the eighth embodiment.
(1) Namely, the moving object information storage device 3 maintains “the moving object information” and generates “the integrity information”.
(2) Further, before the storage-side communicating unit 801 transfers “the moving object information”, “the device-side unique information”, and “the integrity information” to the moving object information verification device 600 (the service provider), the communicating partner authenticating unit 901 authenticates the moving object information verification device 600 (the verification-side communicating unit 802) which is a communicating partner. An authentication method can be a method using a random number as shown in
(3) Further, if the authentication succeeds, the storage-side communicating unit 801 sends “the moving object information”, “the device-side unique information”, and “the integrity information” to the moving object information verification device 600.
(4) If the authentication fails, transmission of “the moving object information”, etc. is not done. For example, the control unit 22 records information for which the authentication fails by the communicating partner authenticating unit 901 in the storage unit 21.
(5) Then, the moving object information verification device 600 carries out verification and process using “the moving object information”, “the device-side unique information”, and “the integrity information” received by the verification-side communicating unit 802. The subsequent process is the same as the one of the eighth embodiment.
As discussed above, the moving object information storage device 3 sends (outputs) “the moving object information”, “the device-side unique information”, and “the integrity information” after authenticating the communicating partner (outputting destination) by the storage-side communicating unit 801 and confirming that it a correct communicating partner. Therefore, improper actions such as analyzing communication data can be prevented, so that a highly reliable moving object information storage device 3 or a highly reliable moving object information guaranteeing system can be provided to the service provider.
In the following, the tenth embodiment will be explained by referring to
The storage-side communicating unit 801 communicates with the IC card 1001 and sends (outputs) “the moving object information”, “the device-side unique information”, and “the integrity information” to the IC card 1001.
The verification-side communicating unit 802 communicates with the IC card 1001 and reads information inside the IC card 1001.
The IC card 1001 is an exchangeable storage medium.
The verification-side communicating unit 802 can be configured so as to receive “the moving object information”, etc. from a PC (Personal Computer) through the Internet or the mobile phone when the IC card 1001 is connected to the PC of the user's home.
In another way, the verification-side communicating unit 802 can be configured so as to receive “the moving object information”, etc. from an exclusive terminal through the Internet or the mobile phone when the IC card 1001 is connected to an exclusive terminal provided at an office of the service provider or an exclusive terminal of the service provider provided at a gas station, a convenience store, an automobile dealer, a car maintenance factory. If the Internet is used, in order to form a safe communication channel, such as SSL (Secure Socket Layer) or a virtual private network should be employed.
Here, as well as other embodiments, the moving object information storage device 3 can include the separation preventing unit 302 or the communicating partner authenticating unit 901. In such a case, the communicating partner authenticating unit 901 authenticates the IC card 1001.
Next, the operation will be explained by referring to
(1) The moving object information verification device 600 (the service provider) stores the signature key in the moving object information storage device 3 and maintains the verification key.
(2) The moving object information storage unit 32 of the moving object information storage device 3 records “the moving object information”.
(3) The tamper preventing unit 20 generates “the integrity information” using the signature key at a necessary timing.
(4) Then, the storage-side communicating unit 801 sends “the moving object information”, “the device-side unique information”, and “the integrity information” to the IC card 1001 (S33).
(5) These information is recorded in the IC card 1001 (S40).
(6) The information inside the IC card 1001 is read by the verification-side communicating unit 802 (S34).
(7) After the verifying unit 601 of the moving object information verification device 600 verifies using the verification key, the processing unit 701 processes “the moving object information” and “the device-side unique information”.
Although in an example of
As discussed above, by using the IC card 1001, it is possible to construct the system easily.
In the following, the eleventh embodiment will be explained by referring to
The eleventh embodiment is an embodiment in which the storage-side communicating unit 801 sends (outputs) “the moving object information”, “the device-side unique information”, and “the integrity information” at a prescribed time interval.
As “prescribed time interval”, “time interval” is defined as
first, “moving object information a”, “integrity information a”, and “device-side unique information a” are sent;
next, “moving object information b”, “integrity information b”, and “device-side unique information a” are sent; and
then, “moving object information c”, “integrity information c”, and “device-side unique information a” are sent, so that the storage-side communicating unit 801 possibly always does transmission without a halt. Here, only “device-side unique information a” is not changed, but “device-side unique information a” is information to specify the moving object, which is usually unchanged.
(1) The moving object information verification device 600 (the service provider) stores the signature key in the moving object information storage device 3 and maintains the verification key (S30).
(2) The moving object information storage unit 32 of the moving object information storage device 3 records “the moving object information” (S31).
(3) The tamper preventing unit 20 of the moving object information storage device 3 generates “the integrity information” using the signature key (S32).
(4) Further, the storage-side communicating unit 801 sends “the moving object information”, “the device-side unique information”, and “the integrity information” to the moving object information verification device 600 (the service provider) (S33).
(5) The moving object information storage device 3 repeats this process. The moving object information verification device 600 receives “the moving object information”, “the device-side unique information”, and “the integrity information” by the verification-side communicating unit 802 (S34).
(6) The verifying unit 601 verifies using the verification key (S35), and
(7) then, the processing unit 701 processes “the moving object information” and “the device-side unique information” (S36).
Here, needless to say, the above can be implemented using the same configuration with
As discussed above, since the storage-side communicating unit 801 always sends “the moving object information”, “the device-side unique information”, and “the integrity information” to the moving object information verification device 600 (the service provider) at a time interval of transmission, the memory capacity of the storage unit 21 can be reduced.
In the following, the twelfth embodiment will be explained by referring to
The sensor confirming unit 1201 is provided at the moving object information storage device 3 and has a function to confirm the sensors 2a, etc. connected to the moving object information storage device 3. In
Next, the operation will be explained.
(1) The sensor confirming unit 1201 confirms the sensor 2a, the sensor 2b, the sensor 2c, etc. connected to the moving object information storage device 3 at a necessary timing. The same confirmation method can be taken as a method to confirm the moving object as shown in
(2) As a result of confirmation by the sensor confirming unit 1201, if the sensors 2a, etc. are correct, the control unit 22 records “the moving object information” in the moving object information storage unit 32. The above process is done by the moving object information storage device 3 for all sensors connected.
The timing for confirming the sensors can be at the time of starting the engine, at a predetermined or random time interval, or at the time of extracting “the moving object information”. When no response is obtained or the confirmed result shows the sensors are wrong, the process depends on the service provider; however, it is also possible to cancel recording “the moving object information”. Or that no response is obtained can be recorded in the storage unit 21 and send to the moving object information verification device 600 with “the device-side unique information”. Or that the sensors are wrong is recorded in the storage unit 21 and send to the moving object information verification device 600 with “the device-side unique information”.
As discussed above, in the moving object information storage device 3, the sensor confirming unit 1201 confirms that the connected sensors are correct or not, which prevents incorrect action to the sensors, and further increases reliability of information.
In the following, the thirteenth embodiment will be explained by referring to
In the figure, the range judging unit 1301 judges if “the moving object information” matches “the prescribed conditions” or not, and if it is judged to match, the moving object information is stored in the moving object information storage unit 32 by the range judging unit 1301. For example, the range judging unit 1301 records “the moving object information” when it exceeds the prescribed range. The range judging unit 1301 judges if it is within “the prescribed range” (an example of conditions) or not. Here, although the range judging unit 1301 is connected to the control unit 22, another configuration can be done, in which the range judging unit 1301 is provided between the sensors and the control unit 22, outputs “the moving object information” to the control unit 22 when it is outside the range (exceeds the range), and does not output when it is within the range.
Next, the operation will be explained by referring to
Further, for another example, when the number of sudden startings exceeds the prescribed number, such a fact can be recorded as “the moving object information”.
As discussed above, in the moving object information storage device 3 according to the thirteenth embodiment, the range judging unit records “the moving object information” which exceeds the prescribed range, but does not record “the moving object information” if it is within the range, so that the memory capacity of the moving object information storage unit can be reduced.
In the following, the fourteenth embodiment will be explained by referring to
In
In
Next, concrete operation of the moving object information storage device 3 will be explained by referring to
(1) The service provider A (the moving object information verification device 600A) stores a signature key A and service information A showing “moving object information” to be used in the moving object information storage device 3 and maintains the verification key A. (S50).
(2) The similar process is done by the service provider B (the moving object information verification device 600B) (S51).
(3) The selecting unit 1401 of the moving object information storage device 3 generates, for example, a service management table 1402 shown in
(4) Then, using each of the moving object information and the service management table 1402, the selecting unit 1401 selects “the moving object information” necessary for each service and generates “moving object information group A” (selected information group) and “moving object information B” (selected information group) (S52)
(5) The selected “respective moving object information groups” are recorded in the moving object information group storage unit 34 (selected information group storage unit) of the storage unit 21.
(6) The tamper preventing unit 20 generates “integrity information” based on “the moving object information group” and “the device-side unique information” using the corresponding signature key at a necessary timing (S53). At this time, since the selecting unit 1401 also manages the relation between the stored signature key and corresponding service, the tamper preventing unit 20 can generate “the integrity information” using the corresponding signature key.
(7) Then, the moving object information storage device 3 outputs “the moving object information group”, “the device-side unique information”, and “the integrity information” according to the service provider (the moving object information verification device).
(8) In
(9) The moving object information verification device 600A of the service provider A obtains “the moving object information group”, “the device-side unique information”, and “the integrity information”, verifies and processes them. For example, the moving object information verification device 600A of the service provider A obtains “the moving object information group A”, “the device-side unique information”, and “the integrity information A” (S55), verifies (S56), and processes (S57).
Here, in this example, after “the integrity information” is generated, “the moving object information”, “the device-side unique information”, and “the integrity information” are outputted; however, after “the integrity information” is generated before it is recorded in the integrity information storage unit 33 of the storage unit 21, the information can be outputted together, or “the moving object information group” and “the integrity information” can be always outputted as
As discussed above, since the moving object information storage device 3 can manage/record “the moving object information” corresponding to plural services, plural services can be received using one moving object information storage device 3, and further, services can be added.
The moving object information storage device 3 of the fourteenth embodiment records plural “moving object information” corresponding to the services. The fifteenth embodiment will show an embodiment in which “the moving object information group” is generated corresponding to plural services by selecting from “the moving object information” recorded.
The moving object information storage device 3 and a group of sensors 2 in the moving object information guaranteeing system in such a case can be accomplished by the same configuration as
Next, the operation will be explained.
(1) The moving object information storage device 3 records all “moving object information” in the moving object information storage unit 32 of the storage unit 21.
(2) And, when outputting “the moving object information” to the outside of the moving object information storage device 3, the selecting unit 1401 refers to the service information and selects necessary type of “the moving object information” from the moving object information storage unit 32.
(3) The tamper preventing unit 20 generates “the integrity information” from “the moving object information group (selected information group)” composed of the moving object information selected by the selecting unit 1401 and “the device-side unique information (specifying information)”.
(4) At this time, since the selecting unit 1401 also manages the relation between the stored signature keys and the corresponding services, the tamper preventing unit 20 can use the corresponding signature key for generating “the integrity information”.
(5) Then, the moving object information verification device 600 of the service provider obtains the selected “moving object information group”, “device-side unique information” and its “integrity information”, and verifies/processes them.
Like this, since the selecting unit 1401 selects and sends the necessary information from the recorded “moving object information”, the moving object information storage device 3 of the fifteenth embodiment can deal with plural services, and at the same time can handle plural services with less memory capacity. Further, services can be added.
In the following, the sixteenth embodiment will be explained by referring to
The man-machine interface unit 1601 provides the user with an operation of the moving object information storage device 3 and responds with the processed result, etc. The man-machine interface unit 1601 receives the operation by an operator and commands the storage-side communicating unit 801 to send (output) based on the operation received. The storage-side communicating unit 801 outputs “the moving object information”, “the device-side unique information”, and “the integrity information” in response to the command from the man-machine interface unit 1601.
Concretely, in such a configuration, when it is necessary to output “the moving object information”, the man-machine interface unit 1601 receives an outputting command from the user by the prescribed operation. Receiving the outputting command from the user, the man-machine interface unit 1601 commands the storage-side communicating unit 801 to output. When the output is commanded by the man-machine interface unit 1601, the storage-side communicating unit 801 outputs the recorded “moving object information”, “device-side unique information” and “integrity information”.
Further, another configuration can be done so that the man-machine interface unit 1601 generates and outputs “the integrity information” from “the moving object information” and “the device-side unique information” after the outputting command is inputted from the user. Here, the timing of outputting “the moving object information” can be recommended to the user through the man-machine interface unit 1601 by judgment of the moving object information storage device 3 from a request of the service provider to the user or from the remaining memory capacity of the storage unit 21.
Like this, it is possible to obtain the user's approval at the time of outputting, so that the service provider can obtain “the moving object information” at the cost which has been approved by the user.
In the following, the seventeenth embodiment will be explained by referring to
The operator is a correct user or a correct service provider. Here, as well as other embodiments, the moving object information storage device 3 can include the separation preventing unit 302, the storage-side communicating unit 801, the communicating partner authenticating unit 901, the sensor confirming unit 1201, the range judging unit 1301, and the selecting unit 1401.
In the above configuration, when “the moving object information” is outputted, the moving object information storage device 3 requests the operator to input (operate) information for authentication using the man-machine interface unit 1601. For example,
As discussed above, the moving object information storage device 3 of the seventeenth embodiment is provided with the operator authenticating unit to authenticate the operator, so that “the moving object information”, “the device-side unique information”, and “the integrity information” can be outputted by only the correct operator from the moving object information storage device 3, which improves the reliability.
In the following, the eighteenth embodiment will be explained by referring to
The encrypting unit 1801 encrypts “the moving object information”. The decrypting unit 1802 decrypts the information obtained. Here, as well as other embodiments, the moving object information storage device 3 can include the separation preventing unit 302, the storage-side communicating unit 801, the communicating partner authenticating unit 901, the sensor confirming unit 1201, the range judging unit 1301, the selecting unit 1401, the man-machine interface unit 1601, etc.
In the above configuration, before outputting “the moving object information”, the moving object information storage device 3 generates “the integrity information” as well as the other embodiments. Then, “the moving object information” is encrypted by the encrypting unit 1801. The eighteenth embodiment defines “the moving object information” as an encryption target; the encryption can be done including “the integrity information” and “the device-side unique information”. If “the integrity information” is defined as the encryption target, the hash value shown in
As discussed above, since the encrypted “moving object information” is outputted, it is possible to maintain the confidentiality of personal information related to the user as “the moving object information” even if eavesdropping is done in the communication channel or if the IC card 1001 is lost, so that the service provider can provide the service securely.
In the following, the nineteenth embodiment will be explained by referring to
In the above configuration, in the same manner as other embodiments, the broker obtains “the moving object information”, “the device-side unique information”, and “the integrity information”. Then, the verifying unit 601 verifies “the integrity information” and keeps “the moving object information” which is confirmed that no tampering is done. The service provider receives “the moving object information” from the broker and processes the information by the processing unit 701.
As discussed above, the broker verifies the integrity of “the moving object information” and the service provider can use the verified “moving object information”, so that the service provider can inject the resource for providing the service. Further, even if the service provider is changed, for example, an insurance underwriter A is changed to an insurance underwriter B, the user does not need to change the signature key, so that the user does not need to change but can keep using the moving object information storage device 3. Further, when the user receives services from plural different service providers, the broker obtains all “moving object information” from the moving object information storage device 3 and the service provider can obtain only necessary information from the broker, so that it is not necessary to store the signature key or information corresponding to the plural services in the moving object information storage device 3, which enables to reduce the memory capacity of the storage unit 21.
In the following, the twentieth embodiment will be explained by referring to
In the following, the twenty-first embodiment will be explained by referring to

The twenty-second embodiment will be explained by referring to
In
(1) The object 2001 is something in storage or transportation.
(2) Each of the sensors 2002a, etc. forming a group of sensors 2002 is provided at a place such as the above “loading space, luggage carrier, cargo room, container, warehouse”. Each of the sensors 2002a, etc. detects the environment information related to the environment for transportation or storage of the object.
(3) The environment information storage device 2003 stores the environment information detected by the sensors 2002a, etc. connected.
The sensors 2002a, etc. can calculate the information detected by itself and output the calculated result to the environment information storage device 2003 as the environment information. Or, as discussed later in the twenty-third embodiment, the environment information storage device 2003 can be configured to input information from each of the sensors 2002a, etc., calculate, and store the calculated result as the environment information. Or, the environment information storage device 2003 can be configured to input the information which has been detected by the sensor and not yet calculated, and store the inputted information as the environment information without calculation. The environment information as the calculated result by the sensor, the calculated result by the environment information storage device 2003, or the information inputted by the sensor include abnormal temperature or humidity that exceeds a prescribed range, the number of times of its occurrence, the number of opening/closing of a door, video information during the transportation or storage, etc. Like this, in this specification, “the environment information” includes any of the information which has been detected by the sensor but not calculated yet, the information which has been detected and calculated by the sensor, and the information which has been detected by the sensor and calculated by the environment information storage device 2003 (the calculated result). Namely, “the environment information” (an example of sensor information) is information based on the information inputted from the sensor. Here, “based on” means to include all of the information which has been detected by the sensor but not calculated yet, the information which has been detected and calculated by the sensor, and the information which has been detected by the sensor and calculated by the environment information storage device 2003.
Further, the environment information storage device 2003 can be provided at the same place with the sensor, or can be provided at a different place. For example, in the case of warehouse, the sensor and the environment information storage device 2003 can be provided within the warehouse, or the environment information storage device 2003 can be provided at an office outside the warehouse.
Further, the connection between the sensor and the environment information storage device 2003 can be connected wired or wirelessly.
A configuration of the environment information storage device 2003 will be explained by referring to
In the following, the operation will be explained using
(1) The control unit 2022 of the environment information storage device 2003 starts recording environment information detected by the sensor (S2101) from “necessary timing”. This “necessary timing” is, for example, is when an engine starts in the case of traffic means; when a door closes in the case of a warehouse, a cargo room, or a container. Or this “necessary timing” can be a timing for starting transportation or storage of an object such as the environment information detected by one or plural sensors enters a prescribed range such as when a switch (not illustrated) provided at the environment information storage device 2003 is turned ON, or when the illuminance sensor detects the brightness and it becomes dark.
(2) To the control unit 2022, the environment information detected by all the sensors connected is inputted. And the control unit 2022 stores the environment information in the environment information storage unit 2032 of the storage unit 2021 (S2102).
(3) The device-side specifying information storage unit 2031 stores the specifying information beforehand. Here, “the specifying information” is information which can specify environment at which the sensor is placed or a place at which the environment information storage device 2003 is previously appointed to be equipped; concretely, “the specifying information” is license plate information, a vehicle identification number, a production number, etc., that is, information cable to specify a loading space or a container in the case of transportation vehicle such as a truck having one loading space. The tamper preventing unit 2020 generates the integrity information based on the environment information stored in the environment information storage unit 2032 of the storage unit 2021 and the specifying information which can specify the environment stored in the device-side specifying information storage unit 2031 of the storage unit 2021 by the command from the control unit 2022 at the necessary timing (S2103).
(4) Here, “the integrity information” (an example of tamper verifying information) is information used for verifying if the environment information, etc. is tampered or not. In this twenty-second embodiment, the tamper preventing unit 2020 generates the integrity information based on the environment information and the specifying information. In this case, the integrity information is used for verifying if at least either the specifying information or the environment information is tampered or not. Further, as will be discussed later by
(5) The integrity information generated is stored in the integrity information storage unit 2033 of the storage unit 2021. Or the integrity information stored in the integrity information storage unit 2033 is outputted to the outside of the environment information storage device 2003 with the environment information. These operations depend on a system to which the environment information storage device 2003 is applied. On recording the integrity information generated by the tamper preventing unit 2020 in the integrity information storage unit 2033, the control unit 2022 of the environment information recording device 20003 manages correspondence relation between the integrity information and the environment information based on which the integrity information is generated. This management clarifies the correspondence relation between the integrity information and the environment information based on which the integrity information is generated (S2104).
(6)
(7) A timing for generating the integrity information depends on an object to which the environment information storage device 2003 of the twenty-second embodiment is applied; for example, when the storage unit 2021 includes the environment information of which the integrity information has not been generated when an event occurs such as opening/closing a door, when the environment information is outputted to the outside of the environment information storage device 2003, when the environment information is inputted to the environment information storage device 2003, when the prescribed event occurs, etc.
As discussed above, the tamper preventing unit 2020 generates the integrity information which verifies the integrity of the environment information inside of the environment information storage device 2003, so that a highly reliable environment information storage device storing environment information can be accomplished.
In the following, the twenty-third embodiment will be explained referring to
As discussed above, since the control unit 2022 includes the device-side operating unit 2201 for calculating the signals detected by the sensors, various types of moving conditions or moving status can be obtained and stored without adding sensors depending on information to be obtained. Further, the environment information storage device 2003 can record only the environment information which exceeds the prescribed range or the number of occurrences of events in the environment information storage unit 2032, which can reduce memory capacity of the environment information storage device 2003.
Here, although the calculated result is stored as the environment information in the twenty-third embodiment, it is possible to configure so as to store the information detected by the sensors together as the environment information.
Further, the environment information in the following embodiments includes both of the information detected by the sensors (information which has not been calculated, information which has been calculated) and calculated result of the control unit 2022.
In the following, the twenty-fourth embodiment will be explained by referring to
The existence detecting unit 2023 outputs existence information when detecting an existence of the object 2001. In the configuration shown in
Namely, in the twenty-second embodiment, the tamper preventing unit 2020 generates the integrity information from the environment information and the specifying information as:
“the environment information+the specifying information→the integrity information”
On the other hand, in the twenty-fourth embodiment, the tamper preventing unit 2020 generates the integrity information from the environment information, the specifying information, and the existence information as:
“the environment information+the specifying information+the existence information→the integrity information”. The integrity information generated from the environment information, the specifying information, and the existence information is information used for verifying if at least either the environment information, the specifying information, or the existence information is tampered or not.
More concrete case will be explained.
(1) A warehouse/container 2040 shows a warehouse or a container for keeping an object 2001 during the transportation or storage.
(2) A door/cover 2041 shows a door or a cover provided at the warehouse or the container.
(3) An opening/closing detecting sensor 2042 detects opening/closing of the door or the cover.
(4) A wireless tag 2043 is mounted on the object 2001 and includes unique identifying information
(5) A wireless tag reader 2044 reads the identifying information of the wireless tag 2043.
(6) An identifying information comparing unit 2045 is connected to the control unit 2022. Further, the identifying information comparing unit 2045 inputs the identifying information from the wireless tag reader 2044, compares the identifying information inputted last time and the identifying information inputted this time, and compared result is outputted to the environment information storage unit 2032 as the existence information. The existence detecting unit 2023 of
(7) Here, as discussed above in the twenty-second embodiment, the environment information storage device 2003 can be provided outside of the warehouse or the container.
In the configuration as shown in
During the transportation or storage, the identifying information comparing unit 2045 reads the identifying information of the wireless tag 2043 through the wireless tag reader 2044 at a necessary timing. This timing can be always reading, at a predetermined interval, when a door or a cover opens/closes, or when the integrity information is created. Then, the identifying information comparing unit 2045 of the environment information storage device 2003 compares later identifying information than the identifying information read by the wireless tag reader 2044 first, that is, the identifying information which is read at or after second time with the identifying information which is read first, and the compared result is outputted as “existence information”. Further, if the wireless tag reader 2044 reads the identifying information when the tamper preventing unit 2020 creates the integrity information, assuming the identifying information read by the wireless tag reader 2044 as the existence information, the tamper preventing unit 2020 can create the integrity information based on the existence information and the environment information. When the identifying information is used directly as the existence information, the identifying information comparing unit 2045 outputs the identifying information inputted from the wireless tag reader 2044 to the environment information storage unit 2032 of the storage unit 2021 directly.
As discussed above, since the environment information storage device includes the existence detecting unit, it is possible to detect if an object exists in the environment recorded by the environment information storage device. Therefore, the correspondence relation can be ensured between the environment information and an object, which enables to accomplish an environment information storage device with higher reliability.
In the following, the twenty-fifth embodiment will be explained by referring to
In this configuration, the environment information storage device 2003 obtains and stores environment information from each sensor of the group of sensors 2002-1 and the group of sensors 2002-2 provided at the warehouse or the container. Then, the environment information storage device 2003 generates the integrity information based on the specifying information which can specify the warehouse/container 2040a for the environment information obtained from each sensor of the group of sensors 2002-1. Further, the environment information storage device 2003 generates the integrity information based on the specifying information which can specify the warehouse/container 2040b for the environment information obtained from each sensor of the group of sensors 2002-2.
As discussed above, the environment information storage device according to the twenty-fifth embodiment obtains and records the environment information from plural groups of sensors placed at plural environments which are different each other such as plural warehouses or containers. Therefore, it is possible to reduce the cost for the environment information storage device.
In the following, the twenty-sixth embodiment will be explained by referring to
The above twenty-second through twenty-fifth embodiments relate to the environment information storage device 2003. In this twenty-sixth embodiment, a case will be explained, in which a terminal device 2600 includes a verifying unit 2601 verifying the correctness of the environment information and the specifying information in the environment information guaranteeing system 2000 including the environment information storage device 2003 and the terminal device 2600.
Next, the operation will be explained. The operation of the environment information storage device 2003 is the same as the one of the twenty-second through twenty-fifth embodiments. Namely, the environment information storage device 2003 keeps the environment information and the specifying information, or keeps the existence information which has been discussed in the twenty-fourth embodiment depending on a case, and generates the integrity information. Then, the terminal device 2600 verifies that the environment information or the existence information is not tampered. The following shows a flow of the verification will be explained by referring to
(An Example of Verification)
(The Environment Information Storage Device 2003)
(1) The tamper preventing unit 2020 inputs the environment information (the existence information can be included) and the integrity information to a hash function to obtain a hashed value (S2001). In the twenty-sixth embodiment, a case will be explained, in which the existence information is not included in the environment information. By encrypting the hash value using the signature key, the tamper preventing unit 2020 generates the integrity information (S2002). The signature key which corresponds to a verification key included in the terminal device 2600 is previously stored in the storage unit 2021 of the environment information storage device 2003.
(The Terminal Device 2600)
(2) The terminal device 2600 obtains the environment information, the integrity information, and the integrity information. As for a method for obtaining, it is possible to obtain through recording medium, or it is also possible to obtain by communication between the terminal device 2600 and the environment information storage device 2003.
(3) The verifying unit 2601 of the terminal device 2600 obtains a hash value from the obtained environment information and the obtained specifying information as well as the tamper preventing unit 2020 (S2003).
(4) On the other hand, the verifying unit 2601 decrypts the integrity information obtained from the environment information storage device 2003 using the verification key which is previously stored (S2004), and compares the above hash value with the hash value of decrypted result (S2005).
(5) As a result of comparison, if both hash values are recognized to be the same, the verifying unit 2601 judges the environment information as correct information, that is, it is not tampered. If the hash values are different, the verifying unit 2601 judges at least one of the environment information and the integrity information.
(Another Example of Verification)
Further,
(The Environment Information Storage Device 2003)
(1) The tamper preventing unit 2020 inputs the environment information (the existence information can be included) to the hash function to obtain a hash value a (S2001a).
(2) In the same way, the tamper preventing unit 2020 obtains a hash value b of the specifying information (S2001b).
(3) Then, the tamper preventing unit 2020 encrypts the hash value a of the environment information and the hash value b of the specifying information using the signature key and generates “integrity information a” corresponding to the environment information and “integrity information b” corresponding to the specifying information (S2002a, S2002b).
(The Terminal Device 2600)
(4) The terminal device 2600 obtains environment information, specifying information, integrity information a, and integrity information b. An obtaining method can be obtaining through storage medium, or obtaining by communication between the terminal device 2600 and the environment information storage device 2003.
(5) Next, the verifying unit 2601 of the terminal device 2600 obtains “hash value a” from the environment information as well as the tamper preventing unit 2020, and at the same time, obtains “hash value b” from the specifying information (S2003a, S2003b).
(6) On the other hand, the verifying unit 2601 decrypts “the integrity information a” and “the integrity information b” using the verification key (S2004a, S2004b), and compares each of “hash value a”, “hash value b” and the hash value which is a decrypted result (S2005a, S2005b)
(7) As a result of the comparison, if the hash values which correspond each other are judged to be the same, the verifying unit 2601 judges that the environment information and the specifying information are correct information, namely, the environment information and specifying information are not tampered. As a result of the comparison, if it is judged to be different, the verifying unit 2601 judges that the environment information and specifying information are tampered. Here, the “another” example shows a case in which the environment information can include the existence information; however, the environment information does not include the existence information, but the integrity information can be generated based on the existence information.
Here, in the twenty-sixth embodiment, an example using the digital signature is shown; however, it is sufficient to generate the integrity information to confirm that the environment information (the existence information can be included), the specifying information or the existence information is not tampered, and another method can be done using such as a message authentication code, electronic watermark, CRC (Cyclic Redundancy Check).
As discussed above, by providing the terminal device 2600 with the verifying unit 2601, a confirming person who is not a dealer can verify that the environment information, the existence information, and the specifying information are not tampered. Therefore, a highly reliable environment information guaranteeing system can be accomplished.
In the following, the twenty-seventh embodiment will be explained by referring to
(1) The storage-side communicating unit 2801 (an example of an outputting unit) is a communicating unit provided at the environment information storage device 2003 and communicates with equipments outside of the environment information storage device 2003 using wireless/wired LAN (Local Area Network), RS232C, Blue tooth (registered trademark), DSRC (Dedicated Short Range Communication), a mobile phone, etc.
(2) Further, the verification-side communicating unit 2802 of the terminal device 2600 receives information sent from the storage-side communicating unit 2801. In
(3) The processing unit 2701 processes the environment information. For example, the processing unit 2701 displays the environment status during the transportation or storage based on the environment information, or displays an abnormal case of the environment information by searching.
(4) Here, as well as other embodiments, the environment information storage device 2003 can include the existence detecting unit 2023.
Next, the operation will be explained by referring to
(The Environment Information Storage Device 2003)
(1) The environment information storage device 2003 records the environment information (S2010).
(2) Then, the tamper preventing unit 2020 generates the integrity information (S2011) at a necessary timing as shown in S2031 and S2032 of
(3) The storage-side communicating unit 2801 sends the environment information and the integrity information to the terminal device 2600 (S2012).
(The Terminal Device 2600)
(4) The terminal device 2600 available to the confirming person receives the environment information and the integrity information by the verification-side communicating unit 2802 (S2013).
(5) The verifying unit 2601 verifies the integrity information (S2014) as shown in S2033 through S2035 of
(6) Then, if the authentication result by the verifying unit 2601 shows correct, the processing unit 2701 processes the environment information (S2015).
In the above example of (1) through (6), the environment information storage device 2003 sends the environment information and the integrity information after generating the integrity information (S2011, S2012). However, as shown in
(a) always; (b) when the transportation or storage finishes; (c) when a prescribed event occurs; (d) a predetermined time interval; and (e) when communication is available.
Here,
As discussed above, the environment information storage device 2003 of the twenty-seventh embodiment sends the environment information and the integrity information to the outside device using the storage-side communicating unit 2801. The outside device can verify/process the information, so that a highly convenient environment information guaranteeing system can be accomplished.
In the following, the twenty-eighth embodiment will be explained by referring to
Next, the operation of the environment information storage device 2003 according to the twenty-eighth embodiment will be explained; however, the operation is the same as the one of the twenty-second embodiment except that the environment information storage device 2003 includes the sensors 2002a, etc. inside.
The environment information storage device 2003 starts recording of the environment information detected by the sensors 2002a, etc. from a necessary timing. This timing can be timings at which the transportation or storage starts such as when an engine starts in the case of traffic means, when a warehouse, a cargo room, or a container closes, when a switch provided separately at the environment information storage device 2003 is turned ON, when the environment information of one or plural sensors enter within the prescribed range such as when an illuminance sensor detects the brightness and it becomes dark, etc.
The environment information detected by all the sensors connected is inputted to the control unit 2022. Then, the control unit 2022 stores the environment information in the device-side specifying information storage unit 2031 of the storage unit 2021. Then, at a necessary timing, by a command of the control unit 2022, the tamper preventing unit 2020 generates the integrity information of the environment information stored in the device-side specifying information storage unit 2031 similarly to S2031 and S2032 shown in
In the twenty-eighth embodiment, the environment information and the integrity information is sent after generating the integrity information; however, after plural pieces of integrity information is generated, the environment information and the integrity information can be sent altogether. Namely, timing to generate the integrity information and timing to send the environment information and the integrity information can be any of the following timings of (a) through (e). (a) always, (b) when the transportation or storage finishes, (c) when a prescribed event occurs, (d) with a predetermined time interval, and (e) when communication is available. Further, as shown in
As discussed above, by including the sensor inside the environment information storage device 2003, modification is not necessary such as providing a new sensor at a loading space, a luggage carrier, a cargo room, a container, a warehouse, etc., so that a highly reliable environment information guaranteeing system can be accomplished with low cost.
In the following, the twenty-ninth embodiment will be explained by referring to
Next, the operation will be explained. The operation of the environment information guaranteeing system 2000 according to the twenty-ninth embodiment is the same as the one of other embodiments. Namely, the environment information storage device 2003 records the environment information and generates the integrity information. Then, the environment information storage device 2003 transfers the environment information and the integrity information to the terminal device 2600 through the storage-side communicating unit 2801. The feature of the twenty-ninth embodiment is that the communicating partner authenticating unit 2901 authenticates the terminal device 2600 which is a communicating partner before this transfer.
(1) The communicating partner authenticating unit 2901 generates a random number (R) (S2020) and sends to the terminal device 2600 (S2021).
(2) The terminal device 2600 receives the random number (R) (S2022), and after encrypting (e(R)) (S2023), sends to the environment information storage device 2003 (S2024).
(3) The communicating partner authenticating unit 2901 of the environment information storage device 2003 receives response data (e(R′)) (S2025), decrypts it (S2026), and compares with the random number (R) generated previously (S2027).
(4) If the comparison results match (S2028), the operation finishes normally, and if mismatch (S2029), the operation finishes abnormally.
Here, in the twenty-ninth embodiment, the communicating partner authenticating unit 2901 of the environment information storage device 2003 carries out the comparison (S2027) after decrypting the received encrypted random number. However, this is one of examples, and the communicating partner authenticating unit 2901 can also encrypt the random number generated by itself and compare the encrypted result and the encrypted random number received from the terminal device 2600. Then, if the authentication succeeds, the storage-side communicating unit 2801 sends the environment information and the integrity information to the terminal device 2600. The terminal device 2600 verifies and processes using the environment information and the integrity information received at the verification-side communicating unit 2802. If the authentication fails, the storage-side communicating unit 2801 does not communicate with the terminal device 2600, but records information that the authentication fails in the storage unit 2021.
In the twenty-ninth embodiment, the random number encrypted at the terminal device is confirmed by the communicating partner authenticating unit 2901 (S2027); however, the terminal device can generate a message authentication code or a digital signature for the received random number to send back to the environment information storage device 2003, and the communicating partner authenticating unit 2901 of the environment information storage device 2003 verifies them.
As discussed above, the environment information and the integrity information are sent to the communicating partner after the storage-side communicating unit 2801 confirms the correct communicating partner as well as authenticating the communicating partner, which prevents fraudulent act such as analyzing the environment information and the integrity information, and an environment information storage device and an environment information guaranteeing system with higher reliability can be accomplished.
In the following, the thirtieth embodiment will be explained by referring to
Next, the operation will be explained using
(1) It is assumed that the sensor keeps “unique information” (sensor-side unique information, hereinafter) which is unique to the sensor. It is also assumed that the environment information storage device 2003 stores “storage-device-side unique information” corresponding to the “sensor-side unique information”. When the sensor is a regular product which is not tampered, “the sensor-side unique information” and “the storage-device-side unique information” match. The control unit 2022 obtains “the sensor-side unique information” from the sensor at a necessary timing (S2040).
(2) Then, the control unit 2022 compares the obtained “sensor-side unique information” with the stored “storage-device-side unique information” (S2041).
(3) If the comparison results match, the control unit 2022 judges as normal and finishes normally (S2042), and records the contents for which the comparison finishes normally in the storage unit 2021. When the comparison results mismatch or when “the sensor-side unique information” cannot be obtained, the control unit 2022 judges as abnormal and finishes (S2043), and records that the operation abnormally finishes in the storage unit 2021. The control unit 2022 performs the above process for all sensors connected.
As discussed above, the control unit 2022 of the environment information storage device 2003 confirms the sensors are correct, which prevents fraudulent act to the sensors, so that an environment information storage device and an environment information guaranteeing system with higher reliability can be accomplished.
In the following, the thirty-first embodiment will be explained by referring to
In the configuration shown in
Like this, the environment information storage device 2003 of the thirty-first embodiment outputs the environment information encrypted by the encrypting unit 3801, so that an environment information storage device or an environment information guaranteeing system which can maintain the confidentiality of the environment information even if the environment information is wiretapped in the communication channel.
In the following, the thirty-second embodiment will be explained by referring to
The above twenty-second through the thirty-first embodiments, the explanation is done that the information such as the specifying information to specify the environment (the twenty-second embodiment), the key used for authentication (the twenty-ninth embodiment), the encrypting key used for encryption (the thirty-first embodiment), etc. are stored in the environment information storage device 2003 beforehand. The “storage information” which is stored in the environment information storage device beforehand such as the specifying information varies according to the organization or the environment in which the system is operated. Therefore, each of the environment information storage device 2003 usually has a different value. Further, the storage information which is once stored sometimes needs to be changed. Consequently, the storage information needs to be recorded/changed after shipment of the environment information storage device.
On the other hand, the storage information is important information in the system to maintain the integrity of the environment information. Therefore, storage of the storage information must be done by a correct organization, persons who belongs to it, a correct terminal, and a correct equipment. Or only correct storage information must be stored as the storage information. Therefore, the following will show an embodiment in which the storage information is stored in the environment information storage device 2003.
