As described above, according to the present invention, there is provided a biometric authentication mechanism that allows a further increase in user convenience.
Preferred embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings. In the specification and the drawings, structural elements having substantially the same functional configuration are denoted by the same reference numerals, and redundant description thereof will be omitted.
An inhaler device generates material to be inhaled by a user. In the example described below, the material generated by the inhaler device is an aerosol. Alternatively, the material generated by the inhaler device may be gas.
The power supply 111A stores electric power. The power supply 111A supplies electric power to the structural elements of the inhaler device 100A under the control of the controller 116A. The power supply 111A may be a rechargeable battery such as a lithium ion secondary battery.
The sensor 112A acquires various items of information regarding the inhaler device 100A. In an example, the sensor 112A may be a pressure sensor such as a condenser microphone, a flow sensor, or a temperature sensor, and acquire a value generated in accordance with the user's inhalation. In another example, the sensor 112A may be an input device that receives information input by the user, such as a button or a switch.
The notifier 113A provides information to the user. The notifier 113A may be a light-emitting device that emits light, a display device that displays an image, a sound output device that outputs sound, or a vibration device that vibrates.
The memory 114A stores various items of information for operation of the inhaler device 100A. The memory 114A may be a non-volatile storage medium such as flash memory.
The communicator 115A is a communication interface capable of communication in conformity with any wired or wireless communication standard. Such a communication standard may be, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark).
The controller 116A functions as an arithmetic processing unit and a control circuit, and controls the overall operations of the inhaler device 100A in accordance with various programs. The controller 116A includes an electronic circuit such as a central processing unit (CPU) and a microprocessor, for example.
The liquid storage 123 stores an aerosol source. The aerosol source is atomized to generate an aerosol. The aerosol source is a liquid such as polyhydric alcohol and water. Examples of the polyhydric alcohol include glycerine and propylene glycol. The aerosol source may include a flavor component that is either derived from tobacco or not derived from tobacco. For the inhaler device 100A that is a medical inhaler such as a nebulizer, the aerosol source may include a medicine.
The liquid guide 122 guides, from the liquid storage 123, the aerosol source that is the liquid stored in the liquid storage 123, and holds the aerosol source. The liquid guide 122 is, for example, a wick formed by twining fiber material such as glass fiber or porous material such as porous ceramic. In this case, the capillary action of the wick guides the aerosol source stored in the liquid storage 123.
The heater 121A heats the aerosol source to atomize the aerosol source and generate the aerosol. In the example illustrated in
The flavor source 131 is a structural element for imparting a flavor component to the aerosol. The flavor source 131 may include a flavor component that is either derived from tobacco or not derived from tobacco.
The airflow path 180 is a flow path of air to be inhaled by the user. The airflow path 180 has a tubular structure having an air inlet hole 181 and an air outlet hole 182 at both ends. The air inlet hole 181 is an inlet of air into the airflow path 180, and the air outlet hole 182 is an outlet of the air from the airflow path 180. The liquid guide 122 is on the airflow path 180 at an upstream position (closer to the air inlet hole 181), and the flavor source 131 is on the airflow path 180 at a downstream position (closer to the air outlet hole 182). Air flowing in through the air inlet hole 181 when the user inhales mixes with the aerosol generated by the heater 121A. Subsequently, as indicated by an arrow 190, the mixture fluid of the aerosol and the air passes through the flavor source 131 and is conveyed to the air outlet hole 182. When the mixture fluid of the aerosol and the air passes through the flavor source 131, the flavor component included in the flavor source 131 is imparted to the aerosol.
The mouthpiece 124 is to be held in a mouth of the user during inhalation. The mouthpiece 124 has the air outlet hole 182. When the user inhales with the mouthpiece 124 in his/her mouth, the mixture fluid of the aerosol and the air enters the oral cavity of the user.
The configuration example of the inhaler device 100A has been described above. The inhaler device 100A is not limited to the above configuration, and may be configured in various ways as exemplified below.
In an example, the inhaler device 100A does not have to include the flavor imparting cartridge 130. In this case, the cartridge 120 includes the mouthpiece 124.
In another example, the inhaler device 100A may include various types of aerosol sources. Still another type of aerosol may be generated by mixing a plurality of types of aerosols generated from the plurality of types of aerosol sources in the airflow path 180 and causing a chemical reaction.
In addition, means for atomizing the aerosol source is not limited to heating by the heater 121A. For example, the means for atomizing the aerosol source may be vibration atomization or induction heating.
The power supply 111B, the sensor 112B, the notifier 113B, the memory 114B, the communicator 115B, and the controller 116B are substantially the same as the respective corresponding structural elements included in the inhaler device 100A according to the first configuration example.
The holder 140 has an internal space 141, and holds a stick substrate 150 in a manner partially accommodated in the internal space 141. The holder 140 has an opening 142 that allows the internal space 141 to communicate with outside. The holder 140 accommodates the stick substrate 150 that is inserted into the internal space 141 through the opening 142. For example, the holder 140 may be a tubular body having the opening 142 and a bottom 143 on its ends, and may define the pillar-shaped internal space 141. The holder 140 also has a function of defining a flow path of air to be supplied to the stick substrate 150. An air inlet hole, which is an inlet of air to the flow path, is disposed in the bottom 143, for example. An air outlet hole, which is an outlet of air from the flow path, is the opening 142.
The stick substrate 150 includes a substrate 151 and an inhalation port 152. The substrate 151 includes an aerosol source. In the present configuration example, the aerosol source is not limited to a liquid, and may be a solid. The stick substrate 150 held by the holder 140 includes the substrate 151 at least partially accommodated in the internal space 141 and the inhalation port 152 at least partially protruding from the opening 142. When the user inhales with the inhalation port 152 protruding from the opening 142 in his/her mouth, air flows into the internal space 141 from the air inlet hole (not illustrated), and the air and an aerosol generated from the substrate 151 reach inside the mouth of the user.
The heater 121B has a configuration similar to that of the heater 121A according to the first configuration example. In the example illustrated in
The heat insulator 144 prevents heat from transferring from the heater 121B to the other structural elements. For example, the heat insulator 144 may be a vacuum heat insulator or an aerogel heat insulator.
The configuration example of the inhaler device 100B has been described above. The inhaler device 100B is not limited to the above configuration, and may be configured in various ways as exemplified below.
In an example, the heater 121B may have a blade-like shape, and may be disposed so that the heater 121B protrudes from the bottom 143 of the holder 140 toward the internal space 141. In this case, the heater 121B having the blade-like shape is inserted into the substrate 151 of the stick substrate 150 and heats the substrate 151 of the stick substrate 150 from its inside. In another example, the heater 121B may be disposed so that the heater 121B covers the bottom 143 of the holder 140. In still another example, the heater 121B may be implemented as a combination of two or more selected from a first heater that covers the outer circumference of the holder 140, a second heater having the blade-like shape, and a third heater that covers the bottom 143 of the holder 140.
In another example, the holder 140 may include an opening/closing mechanism that at least partially opens and closes an outer shell defining the internal space 141. Examples of the opening/closing mechanism include a hinge. In addition, the holder 140 may sandwich the stick substrate 150 inserted into the internal space 141 by opening and closing the outer shell. In this case, the heater 121B may be at the sandwiching position of the holder 140 and may produce heat while pressing the stick substrate 150.
In addition, means for atomizing the aerosol source is not limited to heating by the heater 121B. For example, the means for atomizing the aerosol source may be induction heating.
In addition, the inhaler device 100B may also include the heater 121A, the liquid guide 122, the liquid storage 123, and the airflow path 180 according to the first configuration example. The air outlet hole 182 of the airflow path 180 may also serve as the air inlet hole to the internal space 141. In this case, a mixture fluid of the air and an aerosol generated by the heater 121A flows into the internal space 141, mixes further with an aerosol generated by the heater 121B, and then reaches the oral cavity of the user.
The system 1 according to the present embodiment includes a biometric information acquirer 10, a request acquirer 20, an authenticator 30, and a device controller 40 as logical structural elements. As illustrated in
The inhaler device 100 may have any configuration example among the first configuration example and the second configuration example described above. The inhaler device 100 generates an aerosol by using a substrate including at least one of an aerosol source from which the aerosol is generated or a flavor source from which a flavor to be imparted to the aerosol is generated. The cartridge 120, the flavor imparting cartridge 130, and the stick substrate 150 described above are examples of the substrate in the present embodiment. In the first configuration example, since an aerosol can be generated by combining the power supply unit 110, the cartridge 120, and the flavor imparting cartridge 130, a combination of the power supply unit 110, the cartridge 120, and the flavor imparting cartridge 130 may be regarded as one aerosol generation system. Likewise, in the second configuration example, since an aerosol can be generated by combining the inhaler device 100 and the stick substrate 150, a combination of the inhaler device 100 and the stick substrate 150 may be regarded as one aerosol generation system. In addition, the entire system 1 may be regarded as an aerosol generation system.
The terminal device 200 is a device used by the user of the inhaler device 100. The terminal device 200 is, for example, any information processing device such as a smartphone or a tablet terminal. The terminal device 200 is associated with the inhaler device 100 in advance. For example, the terminal device 200 is paired with the inhaler device 100 in advance and controls the operation of the inhaler device 100 via wireless communication or acquires and stores the operation history of the inhaler device 100. Depending on the communication standard for wireless communication between the inhaler device 100 and the terminal device 200, the terminal device 200 does not necessarily have to be associated with the inhaler device 100 in advance.
The wearable terminal 300 is a device to be worn by the user of the inhaler device 100. The wearable terminal 300 may be of any type such as a wristwatch type, a necklace type, or a contact lens type. The wearable terminal 300 is associated with the terminal device 200 in advance. For example, the terminal device 200 is paired with the wearable terminal 300 in advance and controls the operation of the wearable terminal 300 via wireless communication or acquires and stores the operation history of the wearable terminal 300. The wearable terminal 300 may further be associated with the inhaler device 100 in advance. As an example, the wearable terminal 300 may be directly paired with the inhaler device 100. As another example, the wearable terminal 300 may be associated with the inhaler device 100 indirectly through the terminal device 200 by being paired with the terminal device 200 paired with the inhaler device 100. Depending on the communication standard for wireless communication, the wearable terminal 300 does not necessarily have to be associated with the terminal device 200 or the inhaler device 100 in advance.
Biometric Information Acquirer 10
The biometric information acquirer 10 acquires biometric information of the user. The biometric information is information indicating a physical feature or a behavioral feature of a living body. Examples of the information indicating a physical feature include a fingerprint, a heart rate, a pulse, an iris, a face, a blood vessel, a body temperature, and a voiceprint. Examples of the information indicating a behavioral feature include handwriting and gait. The biometric information acquirer 10 acquires at least one of these pieces of biometric information.
In particular, the biometric information acquirer 10 repeatedly acquires biometric information at a predetermined cycle. For example, the biometric information acquirer 10 periodically acquires biometric information for reasons such as lifelogging. When acquiring the biometric information, the biometric information acquirer 10 transmits the acquired biometric information to the authenticator 30. At this time, the biometric information acquirer 10 may transmit information indicating a timing (for example, time) at which the biometric information is acquired to the authenticator 30 together with the biometric information. Alternatively, the authenticator 30 may handle a timing at which the biometric information is received as the timing at which the biometric information is acquired. The biometric information acquirer 10 does not necessarily have to acquire biometric information at a predetermined cycle, and may acquire biometric information in response to a predetermined condition. Examples of the predetermined condition include a condition that a request has been given from the user, and a condition that a predetermined operation or a predetermined motion performed by the user has been detected.
The biometric information acquirer 10 according to the present embodiment is mounted on the wearable terminal 300. The biometric information acquirer 10 acquires biometric information by a biometric sensor included in the wearable terminal 300. Examples of the biometric sensor include a fingerprint sensor, a heart rate sensor, a pulse sensor, a blood pressure sensor, a respiration sensor, a temperature sensor, an electromyography sensor, a gyro sensor, an acceleration sensor, a camera, and a microphone.
Request Acquirer 20
The request acquirer 20 acquires a predetermined request from the user. When acquiring the predetermined request, the request acquirer 20 transmits information indicating that the predetermined request has been acquired to the authenticator 30. At this time, the request acquirer 20 may transmit information indicating a timing (for example, time) at which the predetermined request is acquired to the authenticator 30 together with the information indicating that the predetermined request has been acquired. Alternatively, the authenticator 30 may handle a timing at which the information indicating that the predetermined request has been acquired is received as the timing at which the predetermined request is acquired.
The predetermined request is a request for a predetermined operation to be performed on the inhaler device 100. An example of the predetermined request is a request to unlock the inhaler device 100. The inhaler device 100 prohibits or permits generation of an aerosol. The inhaler device 100 can generate an aerosol only in a situation where the generation of an aerosol is permitted. For example, the inhaler device 100 can supply power to the means for atomizing the aerosol source in accordance with a user operation only in a situation where the generation of an aerosol is permitted. Prohibiting the inhaler device 100 from generating an aerosol is also referred to as locking the inhaler device 100. On the other hand, permitting the inhaler device 100 to generate an aerosol is also referred to as unlocking. That is, the predetermined request may be a request for permission to generate an aerosol. In the following, the predetermined request is also referred to as an unlock request.
Alternatively, the predetermined request may be a request to receive a user operation on the inhaler device 100. The inhaler device 100 prohibits or permits reception of a user operation. Only in a situation where the reception of a user operation is permitted, the inhaler device 100 receives the user operation. For example, when the reception of a user operation is permitted, the inhaler device 100 can receive the start of inhalation by the user and the input of predetermined information by the user. Prohibiting the reception of a user operation on the inhaler device 100 may also be referred to as locking the inhaler device 100. On the other hand, permitting the reception of a user operation on the inhaler device 100 may be referred to as unlocking.
The request acquirer 20 according to the present embodiment is mounted on the terminal device 200. Accordingly, the unlock request is acquired by the terminal device 200. For example, the unlock request is acquired as a user input to an input device such as a button or a touch panel of the terminal device 200. Alternatively, the unlock request may be acquired as a voice input or a gesture input.
Authenticator 30
The authenticator 30 performs biometric authentication, based on the biometric information acquired by the biometric information acquirer 10. The authenticator 30 compares the biometric information acquired by the biometric information acquirer 10 with biometric information registered in the past as the biometric information of the user of the inhaler device 100 to perform authentication. For example, the authenticator 30 determines that the authentication is successful when the degree of matching between the two pieces of biometric information is equal to or greater than a threshold, and determines that the authentication fails otherwise.
The authenticator 30 may perform biometric authentication, based on a plurality of types of biometric information. For example, the authenticator 30 performs biometric authentication by using different types of biometric information such as a heart rate and a fingerprint. This configuration enables an increase in authentication accuracy.
The authenticator 30 performs biometric authentication when receiving, from the request acquirer 20, information indicating that the unlock request has been acquired. Then, the authenticator 30 transmits information indicating the result of the biometric authentication to the device controller 40. The information indicating the result of the biometric authentication is information indicating the success or failure of the biometric authentication.
Here, the authenticator 30 performs biometric authentication, based on biometric information acquired before the unlock request is acquired. Specifically, the authenticator 30 stores biometric information received from the biometric information acquirer 10 for at least a predetermined period of time. When receiving the unlock request, the authenticator 30 performs biometric authentication, based on the stored biometric information. This configuration makes it possible to finish biometric authentication earlier than when biometric information is acquired after the unlock request is acquired. Accordingly, a time lag from when the user inputs an unlock request to when unlocking is actually performed can be reduced. In this way, the usability of the inhaler device 100 can be improved.
The authenticator 30 performs biometric authentication, based on the biometric information that is acquired last among the pieces of biometric information obtained by repeatedly acquiring the biometric information. This configuration enables biometric authentication to be performed based on the latest biometric information.
Further, the authenticator 30 performs biometric authentication, based on biometric information that is acquired last among the pieces of biometric information obtained by repeatedly acquiring the biometric information and that is acquired within a predetermined time from the timing at which the unlock request is acquired. This configuration enables biometric authentication to be performed based on the most recent biometric information.
However, the biometric information that is acquired last among the pieces of biometric information obtained by repeatedly acquiring the biometric information may be acquired outside the predetermined time from the timing at which the unlock request is acquired. In this case, the authenticator 30 requests the biometric information acquirer 10 to acquire biometric information. When receiving the request, the biometric information acquirer 10 newly acquires biometric information and transmits the biometric information to the authenticator 30. Then, the authenticator 30 performs biometric authentication, based on the newly acquired biometric information, instead of performing biometric authentication based on the biometric information acquired before the unlock request is acquired. This configuration makes it possible to avoid a situation in which biometric authentication is performed based on old biometric information.
Device Controller 40
The device controller 40 controls the operation of the inhaler device 100 in accordance with the result of the biometric authentication. Specifically, the device controller 40 permits or prohibits the execution of the process of generating an aerosol by the inhaler device 100. That is, the device controller 40 locks the inhaler device 100 or unlocks the inhaler device 100. For example, the device controller 40 permits the generation of an aerosol when the biometric authentication is successful, and prohibits the generation of an aerosol when the biometric authentication fails.
When receiving the information indicating the result of the biometric authentication from the authenticator 30, the device controller 40 controls the operation of the inhaler device 100 in accordance with the received result of the biometric authentication. Specifically, the device controller 40 transmits information indicating permission or prohibition of generation of an aerosol to the inhaler device 100. That is, the device controller 40 transmits an unlock instruction signal or a lock instruction signal to the inhaler device 100. When the generation of an aerosol is permitted, the inhaler device 100 can generate an aerosol in accordance with a user operation. For example, when the generation of an aerosol is permitted, the inhaler device 100 supplies power to the means for atomizing the aerosol source in accordance with a user operation. On the other hand, when the generation of an aerosol is prohibited, the inhaler device 100 does not generate an aerosol. For example, when the generation of an aerosol is prohibited, the inhaler device 100 does not supply power to the means for atomizing the aerosol source according to a user operation. When the reception of a user operation is permitted, the inhaler device 100 receives various user operations on the inhaler device 100. On the other hand, when the reception of a user operation is prohibited, the inhaler device 100 does not receive various user operations on the inhaler device 100.
As illustrated in
Then, the wearable terminal 300 transmits the acquired biometric information to the terminal device 200 (step S104).
When receiving the biometric information, the terminal device 200 stores the received biometric information (step S106).
The terminal device 200 and the wearable terminal 300 repeatedly execute the processing of steps S102 to S106 at a predetermined cycle.
Then, the terminal device 200 acquires an unlock request (step S108).
Then, the terminal device 200 determines whether the timing at which the last acquired biometric information is acquired is within a predetermined time from the timing at which the unlock request is acquired (step S110).
If it is determined that the timing at which the last acquired biometric information is acquired is within the predetermined time from the timing at which the unlock request is acquired (step S110: YES), the terminal device 200 performs biometric authentication, based on the last acquired biometric information (step S112).
On the other hand, if it is determined that the timing at which the last acquired biometric information is acquired is out of the predetermined time from the timing at which the unlock request is acquired (step S110: NO), the terminal device 200 transmits a signal indicating a request for acquisition of biometric information to the wearable terminal 300 (step S114).
When receiving the signal indicating a request for acquisition of biometric information, the wearable terminal 300 acquires biometric information (step S116).
Then, the wearable terminal 300 transmits the acquired biometric information to the terminal device 200 (step S118).
When receiving the newly acquired biometric information, the terminal device 200 performs biometric authentication, based on the newly acquired biometric information (step S120). It is assumed that the biometric authentication is successful in step S112 or S120. In this case, the terminal device 200 transmits an unlock request signal to the inhaler device 100 (step S122).
When receiving the unlock request signal, the inhaler device 100 is unlocked (step S124). Thereafter, the inhaler device 100 generates an aerosol in accordance with a user operation.
While an example in which the request acquirer 20 is included in the terminal device 200 has been described in the present embodiment, the present invention is not limited to such an example. For example, the request acquirer 20 may be included in the inhaler device 100. In this case, when acquiring an unlock request, the inhaler device 100 transmits information indicating that the unlock request has been acquired to the terminal device 200. The other processes are as described above.
The inhaler device 100, the terminal device 200, and the wearable terminal 300 are as described above. The server 400 is a device located on the Internet. For example, the server 400 may be a so-called cloud server.
The system 1 according to the present embodiment includes a biometric information acquirer 10, a request acquirer 20, a first authenticator 30A, a second authenticator 30B, and a device controller 40 as logical structural elements. The biometric information acquirer 10, the request acquirer 20, and the device controller 40 are as described above.
The first authenticator 30A has all of the functions described above for the authenticator 30, except for the function of performing biometric authentication. That is, the first authenticator 30A repeatedly receives and stores biometric information from the biometric information acquirer 10. When receiving, from the request acquirer 20, information indicating that an unlock request has been acquired, the first authenticator 30A transmits the biometric information to be used for biometric authentication to the second authenticator 30B, and causes the second authenticator 30B to perform biometric authentication.
At this time, the first authenticator 30A transmits, to the second authenticator 30B, biometric information that is acquired last among the pieces of biometric information obtained by repeatedly acquiring the biometric information and that is acquired within a predetermined time from the timing at which the unlock request is acquired. However, the biometric information that is acquired last among the pieces of biometric information obtained by repeatedly acquiring the biometric information may be acquired outside the predetermined time from the timing at which the unlock request is acquired. In this case, the first authenticator 30A requests the biometric information acquirer 10 to acquire biometric information, and transmits the newly acquired biometric information to the second authenticator 30B.
The second authenticator 30B has the function of performing biometric authentication among the functions described above for the authenticator 30. Specifically, the second authenticator 30B performs biometric authentication, based on the biometric information received from the first authenticator 30A.
In the present embodiment, the terminal device 200 includes the request acquirer 20, the first authenticator 30A, and the device controller 40, the wearable terminal 300 includes the biometric information acquirer 10, and the server 400 includes the second authenticator 30B.
As illustrated in
Then, the wearable terminal 300 transmits the acquired biometric information to the terminal device 200 (step S204).
When receiving the biometric information, the terminal device 200 stores the received biometric information (step S206).
The terminal device 200 and the wearable terminal 300 repeatedly execute the processing of steps S202 to S206 at a predetermined cycle.
Then, the terminal device 200 acquires an unlock request (step S208).
Then, the terminal device 200 determines whether the timing at which the last acquired biometric information is acquired is within a predetermined time from the timing at which the unlock request is acquired (step S210).
If it is determined that the timing at which the last acquired biometric information is acquired is within the predetermined time from the timing at which the unlock request is acquired (step S210: YES), the terminal device 200 transmits the last acquired biometric information to the server 400 (step S212).
On the other hand, if it is determined that the timing at which the last acquired biometric information is acquired is out of the predetermined time from the timing at which the unlock request is acquired (step S210: NO), the terminal device 200 transmits a signal indicating a request for acquisition of biometric information to the wearable terminal 300 (step S214).
When receiving the signal indicating a request for acquisition of biometric information, the wearable terminal 300 acquires biometric information (step S216).
Then, the wearable terminal 300 transmits the acquired biometric information to the terminal device 200 (step S218).
When receiving the newly acquired biometric information, the terminal device 200 transfers the newly acquired biometric information to the server 400 (step S220).
When receiving the biometric information in step S212 or S220, the server 400 performs biometric authentication, based on the received biometric information (step S222). It is assumed here that the biometric authentication is successful.
Then, the server 400 transmits information indicating that the biometric authentication is successful to the terminal device 200 (step S224).
When receiving the information indicating that the biometric authentication is successful, the terminal device 200 transmits an unlock request signal to the inhaler device 100 (step S226).
When receiving the unlock request signal, the inhaler device 100 is unlocked (step S228). Thereafter, the inhaler device 100 generates an aerosol in accordance with a user operation.
The inhaler device 100 and the wearable terminal 300 are as described above. The present embodiment is different from the first embodiment in that the request acquirer 20, the authenticator 30, and the device controller 40 are included in the inhaler device 100.
The request acquirer 20 according to the present embodiment is mounted on the inhaler device 100. Accordingly, an unlock request is acquired by the inhaler device 100. For example, the unlock request is acquired as a user input to an input device such as a button or a touch panel of the inhaler device 100. Alternatively, the unlock request may be acquired as a voice input or a gesture input. When the predetermined request is a request to receive a user operation on the inhaler device 100, the reception of the user operation means reception of various user operations other than a user input as an unlock request.

Finally, a hardware configuration of an information processing device according to each of the embodiments described above will be described with reference to
As illustrated in
The CPU 901 functions as an arithmetic processing unit and a control circuit, and controls the overall operations of the information processing device 900 in accordance with various programs. The information processing device 900 may include an electric circuit such as a microprocessor, a digital signal processor (DSP), or an application specific integrated circuit (ASIC) instead of or in addition to the CPU 901. The ROM 902 stores programs, operation parameters, and the like used by the CPU 901.

The input device 906 may further include a global navigation satellite system (GNSS) module that receives a GNSS signal from a GNSS satellite (for example, a global positioning system (GPS) signal from a GPS satellite) and measures position information including latitude, longitude, and altitude of the device. Regarding the position information, the input device 906 may transmit and receive a wireless signal to and from another device, and detect a relative position with respect to the other device. The input device 906 may form, for example, the biometric information acquirer 10 or the request acquirer 20.
The output device 907 is a device that outputs information to a user. Examples of such a device include a device that outputs visual information, such as a display and a projector, a device that outputs auditory information, such as a speaker, and a device that outputs tactile information, such as an eccentric motor. For example, the output device 907 outputs a result obtained by various processes performed by the information processing device 900. In each of the embodiments described above, the output device 907 may output the biometric information acquired by the biometric information acquirer 10 or information indicating that an unlock request has been acquired by the request acquirer 20. In addition, the output device 907 may output information indicating the progress or result of a process performed by the authenticator 30, the first authenticator 30A, the second authenticator 30B, or the device controller 40.
The storage device 908 is a device that stores data. Examples of such a device include a magnetic storage device such as an HDD, a semiconductor storage device, an optical storage device, and a magneto-optical storage device. The storage device 908 may include a storage medium, a recording device that records data in the storage medium, a reading device that reads data from the storage medium, and a deletion device that deletes data recorded in the storage medium. For example, the storage device 908 may store the biometric information acquired by the biometric information acquirer 10.
The communication device 909 is a device that communicates with another device in a wired or wireless manner. The communication device 909 performs communication conforming to any communication standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), Long Term Evolution (LTE), low-power wide-area (LPWA), near-field communication (NFC), or universal serial bus (USB). The communication device 909 communicates with the inhaler device 100, the terminal device 200, the wearable terminal 300, or the server 400.
An example of a hardware configuration capable of implementing the functions of the information processing device 900 according to the present embodiment has been described above. Each of the structural elements described above may be implemented using a general-purpose member or may be implemented by hardware specific to the function of each structural element. Thus, the hardware configuration to be used can be changed as appropriate in accordance with the technical level at the time of implementation of the present embodiment.
While preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It will be apparent that those skilled in the art to which the present invention belongs can achieve various modifications or variations without departing from the scope of the technical concept presented in the claims, and it is understood that such modifications or variations also fall within the technical scope of the present invention.
For example, which of the inhaler device 100, the terminal device 200, the wearable terminal 300, and the server 400 includes each of the biometric information acquirer 10, the request acquirer 20, the authenticator 30, the first authenticator 30A, the second authenticator 30B, and the device controller 40 is not limited to that in each of the embodiments described above. That is, each of the biometric information acquirer 10, the request acquirer 20, the authenticator 30, the first authenticator 30A, the second authenticator 30B, and the device controller 40 may be mounted on any one of the inhaler device 100, the terminal device 200, the wearable terminal 300, and the server 400. For example, the biometric information acquirer 10 may be included in the inhaler device 100 or the terminal device 200.
For example, in the embodiments described above, an example in which biometric authentication is performed based on biometric information that is acquired last and within a predetermined time among pieces of biometric information obtained by repeatedly acquiring biometric information has been described. However, the present invention is not limited to such an example. For example, for reasons such as an instruction from the user, biometric information may be suddenly acquired at a timing other than the periodic acquisition of biometric information. If the suddenly acquired biometric information is acquired within a predetermined time of the timing at which the unlock request is acquired, biometric authentication may be performed based on the suddenly acquired biometric information.
For example, in the embodiments described above, an unlock request has been described as an example of the predetermined request from the user. However, the present invention is not limited to such an example. The predetermined request may be a request for execution of any operation on the inhaler device 100. When the biometric authentication is successful, the device controller 40 controls the inhaler device 100 to execute the requested operation. For example, the predetermined request may be a request to be sent to the inhaler device 100 to transmit an operation log. In this case, when the biometric authentication is successful, the device controller controls the inhaler device 100 to transmit an operation log.
A series of processes performed by each of the devices described herein may be implemented using any one of software, hardware, and a combination of software and hardware. A program constituting the software is stored in advance in, for example, an internal or external recording medium (non-transitory medium) of each device. For example, each program is read into a RAM at the time of execution by a computer that controls each of the devices described herein, and is executed by a processor such as a CPU. Examples of the recording medium include a magnetic disk, an optical disk, a magneto-optical disk, and a flash memory. Further, the computer program described above may be distributed via, for example, a network without using a recording medium.
In addition, some or all of the processes executed by the terminal device 200 may be executed by the server 400 or any other server (not illustrated) by using Progressive Web Apps (PWA).
The processes described herein using the flowcharts and the sequence diagrams need not be executed in the illustrated order. Some processing steps may be executed in parallel. Any additional processing step may be used, or some processing steps may be omitted.
The following configurations also fall within the technical scope of the present invention.
