According to the present disclosure, it is possible to provide a mobile body authentication apparatus, a mobile body authentication system, a mobile body authentication method, and a program capable of preventing an autonomously movable mobile body from illegally moving without permission.
Hereinafter, the present disclosure will be described based on embodiments of the present disclosure. However, the disclosure set forth in claims is not limited to the following embodiments. Moreover, it is not absolutely necessary to provide all the configurations to be described in the following embodiments as means for solving the problems. For the sake of clarification of the description, the following description and the drawings are partially omitted and simplified as appropriate. Throughout the drawings, the same symbols are attached to the same or equivalent elements and overlapping descriptions are omitted as necessary. Further, in the drawings, unidirectional arrows may be attached. Each unidirectional arrow indicates the direction of the flow of one signal (data) in a simplified manner, and does not exclude a case in which signals are transmitted bidirectionally.
With reference to
The mobile body to be authenticated may be any autonomously movable mobile body and may be, for example, a vehicle, a flying object, a ship, an autonomous moving robot (a walking robot) of various sizes or shapes. The aforementioned mobile body may or may not be required to have a manipulator on board, or may or may not be able to have a manipulator on board. It is sufficient that the mobile body be able to autonomously move. The aforementioned vehicle may include a self-driving car.
The aforementioned flying object may be an unmanned aircraft (Unmanned Aerial Vehicle (UAV)), a flying car, or the like. Further, the above flying object may be a Vertical Take-Off and Landing Aircraft (Vtol) or an electric VTOL (eVTOL). The flying object may be a tilt-rotor aircraft. The flying object may be a helicopter. Further, while the aforementioned flying object may include, for example, a rotary wing, it is merely an example and the flying object may be the one that can fly by autonomous control. The above flying object may either be an unmanned aircraft that carries a package or the like or a manned aircraft with a passenger on board.
Further, the autonomous movement may be a movement along a route that is set in advance, or may be a movement based on a remote control performed by a user within a moving range that is allowed in advance. Like in a mobile body that performs the latter movement, the mobile body to be authenticated may be controlled so as to move while autonomously performing posture control or the like according to an operation instruction (a moving direction, a moving speed and the like) in accordance with remote manipulation, and may include a mobile body that cannot perform autonomous movement along a route. In this manner, the mobile body to be authenticated may be, for example, a mobile body that moves by remote manipulation or a mobile body that autonomously moves under a predetermined control.
The acquisition unit 1a acquires, from an autonomously movable mobile body, remote identification information, position information indicating the current position of this mobile body, time information indicating the current time in this mobile body, and authentication information. The authentication information may be, for example, information in which remote identification information, position information, and time information are concealed. While the acquisition unit 1a is able to acquire these information items at one time, the procedure of the acquisition is not particularly limited. The acquisition unit 1a may first acquire, for example, remote identification information, position information, and time information, and then acquire authentication information. The acquisition unit 1a is connected to the mobile body to be authenticated via wireless communication, thereby being able to acquire the aforementioned various kinds of information items. This connection may instead be a wired connection depending on the type of the mobile body.
The remote identification information is information for managing a remote operation of the mobile body. The remote identification information may be used to identify a mobile body at a time when it is remotely operated, and therefore it may also be called body identification information. A more specific example of the remote identification information will be described in the second example embodiment.
The authentication information may be generated from the remote identification information, the position information, and the time information according to a method of digital signature, or may be generated by another method such as one-time password. However, the authentication information is not limited thereto and may be any kind of information by which authentication can be conducted by the collation unit 1b that will be described later.
The collation unit 1b executes collation based on all or part of the various kinds of information items acquired by the acquisition unit 1a. When authentication information is used for the collation, the collation unit 1b may include a function of de-concealing (decrypting) the concealed authentication information. The information to be collated with the authentication information in the collation unit 1b is not limited. When the unconcealed information is acquired in the acquisition unit 1a, the collation unit 1b may execute collation using the aforementioned unconcealed information. In this case, the collation unit 1b may be configured to collate the authentication information acquired by the acquisition unit 1a with at least one of the remote identification information, the position information, and the time information acquired by the acquisition unit 1a. Alternatively, the collation unit 1b may collate at least one of the remote identification information, the position information, and the time information acquired by the acquisition unit 1a with the corresponding information stored in advance.
Further, the mobile body authentication apparatus 1 may be formed of its body and a terminal apparatus that can be connected to the body and may cause the above-described terminal apparatus to function as a part of the mobile body authentication apparatus 1. In this case, the above-described terminal apparatus receives, from the mobile body, at least one of position information, time information, and authentication information regarding this mobile body, and executes collation based on the received information, whereby it is possible to detect whether or not unauthorized information or falsified information is transmitted. In this case, the main body side of the mobile body authentication apparatus 1 obtains a result of the detection from the aforementioned terminal apparatus as one of the results of the collation. Further, the main body side of the mobile body authentication apparatus 1 may execute the collation to check whether the authentication information transmitted from the mobile body is legitimate or collate the information transmitted from the mobile body with remote identification information registered in advance, the information on a moving plan for moving the mobile body, or the like. Accordingly, the mobile body authentication apparatus 1 is able to detect spoofing or the like.
The output unit 1c outputs the result of the collation performed in the collation unit 1b. The output destination in the output unit 1c may be, for example, a display device (not shown) that is provided in the mobile body authentication apparatus 1, a terminal apparatus or the like that can be connected to the mobile body authentication apparatus 1, and the output destination may be determined in advance. In this manner, the mobile body authentication apparatus 1 is able to prevent an autonomously movable mobile body from illegally moving without permission by spoofing or the like by performing the aforementioned collation and the output of the result of the collation.
With reference to the flowchart shown in
Note that the mobile body authentication apparatus 1 may include a processor and a storage apparatus, although they are not shown in the drawings. This storage apparatus may include, for example, a non-volatile memory such as a flash memory or a Solid State Drive (SSD). In this case, the storage apparatus included in the mobile body authentication apparatus 1 stores a computer program (hereinafter it will be simply referred to as a program) for executing the aforementioned mobile body authentication method. Further, the processor causes a computer program to be loaded to a buffer memory such as a Dynamic Random Access Memory (DRAM) from the storage apparatus, and executes this program.
Each of the components of the mobile body authentication apparatus 1 may be implemented by special-purpose hardware. Further, some or all of the components of each component may each be implemented by a general-purpose or special-purpose circuitry, processor, or a combination of them. They may be configured using a single chip, or a plurality of chips connected through a bus. Some or all of the components of each apparatus may be implemented by a combination of the above-described circuitry, etc. and a program. Further, a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Field-Programmable Gate Array (FPGA), and so on may be used as a processor. The descriptions regarding the components described here may also be applied to other apparatuses or systems that will be described below in the present disclosure.
Further, when some or all of the components of the mobile body authentication apparatus 1 are implemented by a plurality of information processing apparatuses, circuits, or the like, the plurality of information processing apparatuses, the circuits, or the like may be disposed in one place in a centralized manner or arranged in a distributed manner. For example, the information processing apparatuses, the circuits, and the like may be implemented as a form such as a client-server system, a cloud computing system or the like in which they are connected to each other through a communication network. Further, the functions of the mobile body authentication apparatus 1 may be provided in the form of Software as a Service (SaaS).
As described above, according to this example embodiment, it becomes possible to prevent an autonomously movable mobile body from illegally moving without permission.
Next, a second example embodiment will be described with reference to

Hereinafter, as shown in
In this system, a mobile body to be authenticated other than the mobile body 30 and the mobile body 30 may be of the same type or different types. A functional configuration example of the mobile body 30 will be described later.
The mobile body 30 can be controlled by a remote controller (manipulation apparatus) 32 by a user (operator) P1 or can move completely autonomously along a set route. The remote controller 32, which is an apparatus for remotely controlling the mobile body 30, is able to send an instruction for causing the mobile body 30 to perform a predetermined motion by wireless communication. The remote controller 32 may acquire data or the like of a sensor included in the mobile body 30. Further, the remote controller 32 may transmit predetermined information to the terminal apparatus 20 or the mobile body authentication apparatus 10 via the mobile body 30.
The mobile body authentication apparatus 10 may include a control unit 11 that controls the entire apparatus, a storage unit 12, and a communication unit 13 that performs external communication, and may be constructed as a single apparatus or a system in which the functions thereof are distributed in a plurality of apparatuses. The acquisition unit 1a shown in
Further, the mobile body authentication apparatus 10 may include an instruction receiving unit that receives an instruction for executing collation. In the example shown in
The terminal apparatus 20 may be an apparatus used by an administrator P2 who manages or monitors operations of a plurality of mobile bodies such as the mobile body 30, but it is not limited to an apparatus used by the administrator P2. That is, the terminal apparatus 20 may be an apparatus used by a person other than the administrator P2, such as an ordinary citizen or a police officer. Further, as the terminal apparatus 20, a terminal apparatus used by the administrator P2 and a terminal apparatus used by a person other than the administrator P2 may be incorporated into this system. In this case, information on the mobile body can be received by terminal apparatuses held by the administrator P2 and a person other than the administrator P2. However, in the following description, for the sake of clarification of the description, an example in which the terminal apparatus 20 is used by the administrator P2 will be described. The terminal apparatus 20 may be a portable computer such as a mobile telephone, a smartphone, or a tablet terminal, or may be a stationary Personal Computer (PC).
The remote identification information management system 40 may be one example of a management apparatus that is connected to the mobile body authentication apparatus 10 and manages remote identification information, and may be constructed as a single apparatus or a system whose functions are distributed in a plurality of apparatuses. The remote identification information management system may include a control unit 41 that controls its entirety, a storage unit 42 that stores remote identification information 44 for each mobile body, and a communication unit 43 that performs external communication via, for example, the network N1. In this manner, the remote identification information management system 40 manages the remote identification information 44 for each of the plurality of mobile bodies. This remote identification information 44 may be stored along with a flag indicating valid/invalid, and the content thereof may be manually or automatically updated as appropriate by the management side of the remote identification information management system 40. Further, a moving plan (the moving plan is also referred to as a flying plan when the mobile body 30 is a flying object such as an unmanned aircraft) regarding each mobile body such as the mobile body 30 may be requested and registered in advance in the storage unit 42.
Referring next to
The communication unit 311 includes an interface for enabling connection with the remote controller 32 wirelessly and an interface for enabling connection with the terminal apparatus 20 wirelessly. The radio communication system may be any system as long as there is no interference between these communications.
Further, as described above, in a configuration in which the mobile body 30 directly communicates with the mobile body authentication apparatus 10, the communication unit 311 may include an interface for enabling connection with the mobile body authentication apparatus 10 wirelessly. This wireless communication may be performed by any system.
In this example embodiment, like in the first example embodiment, authentication information, or information such as authentication information, remote identification information, position information, and time information is transmitted from the mobile body 30. While the information may be transmitted to the terminal apparatus 20, it may be transmitted also to the mobile body authentication apparatus 10. In either case, the mobile body 30 may be configured to be able to regularly transmit information such as remote identification information. That is, the mobile body 30 may be a mobile body that is set so as to move while regularly sending information such as remote identification information.
The camera 312 captures an image of scenery for each preset period while the mobile body 30 is moving, and generates image data related to the captured images. The image data related to the images captured by the camera 312 is supplied to the remote controller 32 via the communication unit 311. Further, the mobile body 30 may be configured to transmit this image data to the terminal apparatus 20 (or the mobile body authentication apparatus 10). The sensor group 313 indicates various kinds of sensors included in the mobile body 30. The sensor group 313 may include, for example, an antenna that acquires position information by a Global Navigation Satellite System (GNSS), a gyro sensor, a thermometer, a hygrometer or the like.
The control unit 314 includes a computation apparatus such as a CPU or an MCU and controls the entire mobile body 30. The drive unit 315, which is driven to enable the mobile body 30 to move, includes, for example, a motor for rotating a rotary wing (propeller) 31 used when the mobile body 30 moves. The storage unit 320, which is a storage apparatus including a non-volatile memory such as a flash memory or an SSD, at least stores remote identification information 321. In this example embodiment, processing in which a case where the remote identification information 321 is falsified by an operator P1 or the like is taken into account is performed.
Next, with reference to
As illustrated in
The body information may include a total moving time, a repair history, and the like, and may be dynamically updated. Further, the body information may include a validity period of an operation qualification for operating the target mobile body 30, the body number (body ID), the weight, and the like.
The administrator information may include a body operation achievement, the number of bodies owned, and the like, and they may be dynamically updated. Further, the administrator information may include a validity period of a management qualification regarding the target mobile body 30, the name or the address of the administrator, the address or the location of the administrator, or the like.
The user information may include a movement achievement of a user, an accident history, and the like, and they may be dynamically updated. Further, the user information may include a validity period of a usage qualification for using the target mobile body 30, the name of the user P1, the user's address, and the like.
Referring next to
As described in the first example embodiment, in this example embodiment as well, various kinds of information items from the mobile body 30 are received by the mobile body authentication apparatus 10 as body authentication and anti-spoofing measures, and execute collation. While various kinds of information items may be sent regularly by the mobile body 30, they may also be obtained as a result of the terminal apparatus 20 sending an information transmission request to the mobile body 30.
With the aforementioned configuration, this system is able to perform the following processing in a state in which the administrator P2 is watching the mobile body 30.
When the control unit 11 of the mobile body authentication apparatus 10 has received an instruction for executing collation, the control unit 11 acquires information from the mobile body 30 via the communication unit 13 and executes collation. This instruction may also be performed by the terminal apparatus 20 specifying remote identification information in a state in which the terminal apparatus 20 accesses the remote identification information management system directly or via the mobile body authentication apparatus 10, and viewing the moving schedule, and the terminal apparatus 20 may send an information transmission request to the mobile body 30.
At the time of the collation, the control unit 11 not only executes collation of the acquired authentication information with the remote identification information 321, the time information, and the position information, but also performs the following collation as well. That is, the control unit 11 further executes at least one of collation of time information on the mobile body 30 with time information indicating the current time in itself or the current time in the terminal apparatus 20, or collation of position information on the mobile body 30 with position information indicating the current position of itself or the current position of the terminal apparatus 20.
A specific example will be given. First, the terminal apparatus 20 acquires, from the mobile body 30, position information indicating the current position of the mobile body 30, time information indicating the current time, the remote identification information 321, and the authentication information via radio communication with the mobile body 30. This authentication information may be the one that the mobile body 30 has generated from the remote identification information 321, position information, and time information, and they may be generated by any method.
Further, the data format that is used for the transmission from the mobile body 30 to the terminal apparatus 20 and transmission from the terminal apparatus 20 to the mobile body authentication apparatus 10 that will be described later is not limited. In this example embodiment, authentication (collation) based on authentication information created from the remote identification information including the body ID or the like, the time information, and the position information is executed, and body authentication and anti-spoofing measures are conducted.
Next, the terminal apparatus 20 transmits position information indicating the current position of the terminal apparatus 20 and time position indicating the current time of the terminal apparatus 20 to the mobile body authentication apparatus 10 along with the remote identification information 321, the position information, the time information, and the authentication information received from the mobile body 30.
Further, the mobile body authentication apparatus 10 decrypts (de-conceals) the received authentication information by decoding or the like, and collates the received authentication information with the remote identification information 321, the position information, and the time information that have also been received to check if the received authentication information is the falsified information or not. In this manner, the authentication information is, for example, information generated from the information including the remote identification information 321, the position information, and the time information, and collation may be executed after this authentication information is decrypted.
Further, the mobile body authentication apparatus 10 respectively collates the time information and the position information on the mobile body 30 that have been received with the time information and position information included in an operation plan regarding the received remote identification information 321. Further, the terminal apparatus 20 may transmit the position information and the time information of the terminal apparatus 20 to the mobile body authentication apparatus 10 in advance, and collate the position information and the time information on the mobile body 30 that have been received by the mobile body authentication apparatus 10 with the position information and the time information on the terminal apparatus 20 that have been received. This case means that checking by comparing the position and the time of the terminal apparatus 20 in the terminal apparatus 20 with the position and the time of the mobile body 30 is executed by the mobile body authentication apparatus 10. As a matter of course, this checking may be executed by the terminal apparatus 20. For example, the terminal apparatus 20 may collate at least one of the time information, the position information, and the authentication information received from the mobile body 30 with the time information on itself, the position information on itself, and the authentication information held by itself (bidirectional thin broken arrows in
Further, the mobile body authentication apparatus 10 is also able to access the remote identification information management system 40 to collate the remote identification information 321 received from the terminal apparatus 20 with the remote identification information 44 of the target mobile body 30 stored in the remote identification information management system 40. That is, the mobile body authentication apparatus 10 is also able to collate the acquired remote identification information 321 with the available remote identification information managed by the remote identification information management system 40.
The mobile body authentication apparatus 10 may execute collation of each information item (or receive the result of the collation regarding a part of the information), determine that the collation has been successful when the collation of each of all the information items has been successful, and determine that collation has been failed otherwise. Further, if it is impossible to execute collation, it can be determined that collation has failed in a case where all the necessary information items cannot be received from the mobile body 30, including a case where the mobile body 30 is modified in such a way that it cannot transmit information. Then, the mobile body authentication apparatus 10 outputs the result of the determination (the result of the collation) by replying to the terminal apparatus 20 which is instruction source, or the like. Note that the result of the collation may be output only when the collation has failed. Further, the mobile body authentication apparatus 10 may be configured to transmit the result of the collation to at least one of a system (not shown) of a police that cracks down on suspicious mobile bodies or a system (not shown) in Ministry of Land, Infrastructure, Transport and Tourism.
According to the aforementioned processing, the mobile body authentication apparatus 10 is able to execute body authentication of the mobile body 30 and detection of spoofing regarding the remote identification information, the time, and the position, and output the result of the body authentication and the detection of spoofing. Further, while the above description has been given based on the assumption that all the remote identification information, the position, and the time are collated, this system may be constructed to collate any one or two of the information items.
Further, when authentication has failed (that is, when spoofing or the like has been detected), the mobile body authentication apparatus 10 preferably notifies various destinations as follows that the authentication has failed. The destinations may include one or more of the terminal apparatus 20 used by the administrator P2 or the like, the mobile body 30, or an administrator or a user of the mobile body 30 (a registered person who is a victim of spoofing), an operator of the mobile body authentication apparatus 10, police, Ministry of Land, Infrastructure, Transport and Tourism, and the like.
Further, when the collation has failed, the mobile body authentication apparatus 10 preferably transmits alert information to the mobile body 30 that is a transmission source of the authentication information via the communication unit 13. While this transmission may be executed directly from the mobile body authentication apparatus 10, it may be executed via the terminal apparatus 20 as well. As a matter of course, because the mobile body 30 may be modified in such a way that the alert information cannot be received from the terminal apparatus 20 or that the alert information will be ignored, the mobile body 30 transmits such alert information only when it can perform communication.
Further, the mobile body authentication apparatus 10 may also transmit an instruction for causing the mobile body 30 to be forced to land (a forced-landing signal) via the terminal apparatus 20. In this case as well, this transmission can be executed when the terminal apparatus 20 can communicate with the mobile body 30 and the mobile body 30 is able to receive this instruction without ignoring this instruction.
Further, in this system, the mobile body authentication apparatus 10 accesses the remote identification information management system 40, whereby a configuration in which visual observation by the administrator P2 is not necessary may be employed. In this case as well, as a processing example after the collation, processing similar to that performed with the configuration which requires visual observation may be employed.
It is assumed that the mobile body authentication apparatus 10 acquires position information indicating the current position of the mobile body 30 via the terminal apparatus 20 (or directly) in order to eliminate the need for the visual observation by the administrator P2. Then, at the time of a collation, the mobile body authentication apparatus 10 may further execute collation with the time information and the position information set in the storage unit 42 in advance as an operation plan (a moving plan) for operating the mobile body 30 regarding the time information, the position information, and the remote identification information 321 on the mobile body 30. This operation plan may be the one requested in advance. Note that such a collation with the operation plan may be executed also when visual observation is required.
Further, while the above description has been given based on the assumption that the collation is basically executed only in the mobile body authentication apparatus 10, a part or whole of the collation may be executed by the terminal apparatus 20, as briefly described above. That is, the terminal apparatus 20 may also be configured to execute collation based on the remote identification information, the time information, the position information, and the authentication information, whereby the terminal apparatus 20 is able to detect spoofing. In the case in which the collation is executed in the terminal apparatus 20, the processing for the result of the collation may be basically the same as that described with regard to the mobile body authentication apparatus 10. However, the mobile body authentication apparatus 10 may be included as the destination to which the result of the collation is sent. That is, when authentication has failed (that is, in a case where spoofing or the like has been detected), the terminal apparatus 20 preferably notifies various destinations as follows that authentication has failed. These notification destinations may include one or more of the mobile body authentication apparatus 10, the mobile body 30, the administrator or the user of the mobile body 30 (a registered person who is a victim of spoofing), the operator of the mobile body authentication apparatus 10, police, Ministry of Land, Infrastructure, Transport and Tourism, and so on.
Accordingly, this system may be configured to execute the following collations (1) in a case where the terminal apparatus 20 has received various kinds of information items from the mobile body 30 and (2) in a case where the mobile body authentication apparatus 10 has received various kinds of information items from the mobile body 30. In the case of (1), the terminal apparatus 20 receives the remote identification information, the position information, and the time information from the mobile body 30, collates these information items with the position information and the time information of the terminal apparatus 20, and checks whether or not unauthorized information is sent or any information item is falsified. Further, the terminal apparatus 20 receives authentication information from the mobile body 30 and checks whether or not the mobile body 30 that has sent information is a legitimate mobile body by executing collation with, for example, information to be authenticated prepared in advance. In the case of (2), the mobile body authentication apparatus 10 receives the remote identification information, the position information, and the time information that have been sent by the mobile body 30 from the mobile body 30 or the terminal apparatus 20, compares these information items with the position information and the time information of the flying plan registered in advance for each of remote identification information items, and checks whether or not they match each other. Further, the mobile body authentication apparatus 10 receives the authentication information sent from the mobile body 30 and authenticates whether or not this mobile body 30 that has sent information is the legitimate mobile body by executing collation with, for example, the information to be authenticated prepared in advance.
Referring next to
In this system, first, the mobile body authentication apparatus 10 acquires various kinds of information items (the remote identification information 321, the time information, the position information, and the authentication information) from the mobile body 30 via the terminal apparatus 20 (Step S11). While it is possible to acquire the position information and the time information of the terminal apparatus 20 in Step S11 as described above, if the mobile body authentication apparatus 10 is disposed in a position close to the terminal apparatus 20, the position information indicating the position of the mobile body authentication apparatus 10 or time information may be used as well.
Next, the mobile body authentication apparatus 10 decrypts (de-conceals), of the received information, information that needs to be decrypted (in this case, authentication information) (Step S12), and collates the information after decryption and information that does not need to be decrypted with information prepared by itself (Step S13).
Next, the mobile body authentication apparatus 10 determines whether or not the collation of the mobile body 30 has been entirely successful from the result of the collation regarding each information item (Step S14). When the collation has been successful, information indicating that the collation has been successful is transmitted (output) to the terminal apparatus 20 (Step S15), and thereby the processing is ended. On the other hand, when the collation has failed (in the case of NO in Step S14), information indicating that the collation has failed is transmitted (output) to the terminal apparatus 20 (Step S16), an instruction for stopping the use of the target remote identification information 321 is transmitted to the remote identification information management system 40 (Step S17), and thereby the processing is ended.
Steps S16 and S17 may be performed in any order. Further, as a matter of course, the content of the instruction transmitted in Step S17 may include information indicating that the collation has failed or may be only information indicating that the collation has failed. In the remote identification information management system 40 that has received this instruction or the information indicating that the collation has failed, the control unit 41 causes the remote identification information 321 to stop using the remote identification information 44 that corresponds to at least the body number, or stores the remote identification information 44 as a target that requires special attention.
The remote identification information of a target whose usage should be stopped may be remote identification information where some of the information items (e.g., only the user, or only the user and the administrator) regarding the remote identification information 321 to which a stop-use instruction is sent match each other. The same holds true for the case in which the remote identification information is stored as the target that requires special attention. In this manner, the remote identification information management system 40 may change the state of the remote identification information to a stop-use state or a state which requires special attention as the target whose usage should be stopped or the target that requires special attention. This can be executed by changing the operation qualification or the management qualification or by changing the associated flag. Further, when there is no remote identification information 321 to which the stop-use instruction is sent, the remote identification information management system 40 may store the remote identification information in the storage unit 42 as a target that requires special attention.
As described above, the remote identification information management system 40 manages the remote identification information on each of a plurality of mobile bodies, and when the remote identification information management system 40 has received an instruction for stopping the usage of the remote identification information from the mobile body authentication apparatus 10, the remote identification information management system 40 preferably sets the state of the remote identification information regarding the mobile body related to this instruction to an unable state. Further, while the example in which the instruction for stopping the use of the target remote identification information 321 is transmitted to the remote identification information management system 40 has been described in Step S17, a configuration in which the mobile body authentication apparatus 10 is included in the remote identification information management system 40 may also be employed. In this case, the usage of the target remote identification information 321 is stopped in accordance with the above instruction.
As described above, according to this example embodiment, it becomes possible to prevent a mobile body such as the mobile body 30 from illegally moving without permission.
