[0014] (Embodiment 1) <Configuration> The configuration of an information processing device 10 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the information processing device 10 according to an embodiment. The information processing device 10 has an acquisition unit 11, an authentication unit 12, and a provision unit 13. Each of these units may be realized by cooperation between one or more programs installed in the information processing device 10 and hardware such as a processor 101 and a memory 102 of the information processing device 10.

[0015] The acquisition unit 11 acquires a face image of a second user accompanying a first user using a means of transportation (e.g., an airplane, a train, a bus, etc.) captured by an imaging device. The authentication unit 12 authenticates the first user based on the face image of the second user acquired by the acquisition unit 11. If the authentication by the authentication unit 12 is successful, the provision unit 13 provides a service on the means of transportation appropriate to the first user.

[0016] (Embodiment 2) Next, the configuration of the information processing system 1 according to the embodiment will be described with reference to FIG. <System configuration> 2 is a diagram showing an example of the configuration of an information processing system 1 according to an embodiment. In the example of FIG. The information processing system 1 also has providing devices 30A and 30B (hereinafter, when there is no need to distinguish between them, they will also be simply referred to as "providing device 30"). The information processing system 1 also has photographing devices 40A, 40B, and 40C (hereinafter, when there is no need to distinguish between them, they will also be simply referred to as "photographing device 40"). In the example of FIG. 2, the information processing device 10, the user terminal 20, the providing device 30, and the photographing device 40 are connected so as to be able to communicate with each other via a network N. Note that the numbers of the information processing devices 10, the user terminals 20, the providing devices 30, and the photographing devices 40 are not limited to the example of FIG. 2.

[0017] Examples of the network N include, for example, the Internet, a mobile communication system, a wireless LAN (Local Area Network), a LAN, and a bus, etc. Examples of the mobile communication system include, for example, a fifth generation mobile communication system (5G), a sixth generation mobile communication system (6G, Beyond 5G), a fourth generation mobile communication system (4G), a third generation mobile communication system (3G), etc.

[0018] The information processing device 10 is, for example, a device such as a server, a cloud server, or a personal computer. For example, the information processing device 10 performs authentication based on a face image of a second user who is an accompanying person of a first user who uses a means of transport, and if the authentication is successful, provides a service on the means of transport appropriate for the first user. The first user may be, for example, a person who requires assistance.

[0019] The user terminal 20 is, for example, a terminal such as a smartphone or a tablet that is owned by the first user. The user terminal 20 registers, in the information processing device 10, information on a second user who will accompany the first user, for example, in response to an operation by the first user.

[0020] The providing device 30 is a device that provides a service to a user based on an instruction from the information processing device 10. The providing device 30 may be, for example, a ticket gate or an automatic ticket issuing device in a transportation facility.

[0021] The photographing device 40 is, for example, a camera provided near the providing device 30. The photographing device 40 may be provided so as to be able to photograph a face of a user when the user uses the providing device 30, for example.

[0022] <Hardware configuration> Fig. 3 is a diagram showing an example of a hardware configuration of an information processing device 10 according to an embodiment. In the example of Fig. 3, the information processing device 10 (computer 100) includes a processor 101, a memory 102, and a communication interface 103.

The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire or an optical fiber, or via a wireless communication path.

[0028] <Processing> Next, an example of processing of the information processing device 10 according to the embodiment will be described with reference to Fig. 4 and Fig. 5. Fig. 4 is a flowchart showing an example of processing of the information processing device 10 according to the embodiment. Fig. 5 is a diagram showing an example of information stored in a companion DB (database) 501 according to the embodiment. Fig. 6 is a diagram showing an example of information stored in a user DB 601 according to the embodiment. Note that the processing of Fig. 4 may be executed, for example, when the face of a person is photographed by the photographing device 40 from approximately the front.

[0029] In step S1, the acquisition unit 11 acquires a facial image or the like of a second user accompanying a first user using public transport, captured by the image capture device 40. As a result, even if it is difficult to position the face of the first user, who is a person requiring assistance using a wheelchair, in front of the image capture device 40, for example, an image can be acquired in which the face of the accompanying second user is positioned in front of the image capture device 40.

[0030] Next, the authentication unit 12 authenticates the first user based on the face image of the second user acquired by the acquisition unit 11 (step S2). Here, the authentication unit 12 may refer to the companion DB 501 and identify the second user who is an accompaniment by comparing information on face features for face authentication recorded in the companion DB 501 with information on face features detected from the face image of the second user. The companion DB 501 may be recorded in a storage device inside the information processing device 10 or in a storage device outside the information processing device 10. The information in the companion DB 501 may be stored in advance, for example, by an administrator (operator) of the information processing device 10 or an operation by the second user from a terminal.

[0031] 5, the companion DB 501 stores companion information in association with a companion ID. The companion ID is identification information of the companion. The companion information is personal information of the companion. The companion information may include, for example, facial feature information for face recognition, the name, address, date of birth, and account ID for granting benefits of the companion.

[0032] Then, the authentication unit 12 may refer to the user DB 601 and identify a first user who is accompanied by the second user and requires assistance. The user DB 601 may be recorded in a storage device inside the information processing device 10, or may be recorded in a storage device outside the information processing device 10. Information in the user DB 601 may be stored in advance, for example, by an administrator (operator) of the information processing device 10 or an operation by the first user from the user terminal 20.

[0033] In the example of FIG. 6, the user DB 601 records user information in association with a user ID. In addition, a combination of an accompanying person ID, an accompanying time period, and an accompanying place (an example of a "specific place") is recorded in association with the user ID. The user ID is identification information of a user who requires care. The user information is personal information of the user. The user information may include, for example, information on a face feature amount for face recognition, a name, an address, a date of birth, an account ID for granting benefits, and information indicating a degree of physical disability (a level of necessary assistance, a degree of disability), etc. The accompanying time period is information indicating a time period when the first user uses a means of transportation accompanied by the second user. The accompanying place is information indicating a place where the first user uses a means of transportation accompanied by the second user (for example, an airport name or a station name). The degree of physical disability may be, for example, a value based on a degree of care required determined by a public institution that provides nursing care insurance, etc. The degree of physical disability may be, for example, a value based on the grade of disability listed in the disability certificate issued to the first user.

[0034] Here, the authentication unit 12 may refer to the user DB 601 and identify a user ID of a record (one line of data) associated with the companion ID identified based on the face image of the second user, in which the current time is within the companion time zone and the current location of the second user is within a specific range of the companion location (for example, within a radius of 200 m). The current location of the second user may be, for example, information on the location (place) where the photographing device 40 is installed, which is registered in advance in the information processing device 10. The current location of the second user may be, for example, location information measured by the terminal of the second user using a satellite positioning system such as GPS (Global Positioning System). Thereby, the accompanied person requiring assistance can be identified based on the face image of the companion, etc.

[0035] Then, if the authentication is successful, the authentication unit 12 may output information indicating that the authentication was successful and the identified user ID to the provision unit 13. On the other hand, if the authentication is unsuccessful, the authentication unit 12 may output information indicating that the authentication was unsuccessful and information indicating the cause of the failure to the provision unit 13. Here, the authentication unit 12 may determine that the authentication has failed, for example, when it is unable to identify the companion ID based on the face image or the like of the second user. Also, the authentication unit 12 may determine that the authentication has failed, for example, when it is unable to identify a user ID that matches the identified companion ID or the like.

[0036] (Example of authenticating the first user based on his / her physical disability) The authentication unit 12 may further perform authentication based on the degree of physical disability of the first user. In this case, the authentication unit 12 may acquire information indicating the degree of physical disability included in the user information recorded in the user DB 601, for example. Then, the authentication unit 12 may refuse authentication using the face image of the second user, for example, when the degree of physical disability of the first user is less than a threshold value. Thereby, for example, when the degree of physical disability of the first user is relatively low and it is considered possible to move the face to a position in front of the image capture device 40, the first user can be authenticated using his / her own face image. Therefore, for example, fraudulent use by the second user can be reduced.

[0037] (Example of authenticating based on the first user's current location) The authentication unit 12 may further perform authentication based on the current location of the first user. In this case, the authentication unit 12 may acquire, from the user terminal 20, location information and a user ID measured by the user terminal 20 of the first user using, for example, a satellite positioning system. In addition, when the authentication unit 12 receives a user ID from the user terminal 20 of the first user via the providing device 30 or the photographing device 40 by short-range wireless communication such as BLE (Bluetooth (registered trademark) Low Energy), for example, the authentication unit 12 may acquire location information of the providing device 30 or the photographing device 40 as the current location of the first user.

[0038] Then, it may be determined that the authentication has failed if the current location of the first user is not within a predetermined range of the accompanying location registered in the user DB 601. This can reduce, for example, unauthorized use by the second user when the second user is not accompanying a person requiring assistance.

[0039] (Example of loose authentication of the first user) The providing unit 13 may provide a service in a transportation facility according to the first user when the first authentication based on an image of the face region of the first user with a first image quality (e.g., resolution, number of pixels) and the second authentication based on an image of the face region of the second user with a second image quality higher than the first image quality are successful. This allows for authentication by combining, for example, a relatively low-accuracy authentication based on an image of the face region of the first user who is a person requiring assistance, etc., captured by a surveillance camera, etc., and a relatively high-accuracy authentication based on a face image of the second user who is an accompanying person, etc., captured by a face camera. This can reduce, for example, fraudulent use by the second user when the second user is not accompanying the person requiring assistance, etc.

[0040] Next, the providing unit 13 judges whether the authentication by the authenticating unit 12 has been successful (step S3). If the authentication has failed (NO in step S3), the providing unit 13 transmits (notifies) information indicating the authentication failure to the providing device 30 (step S4), and ends the process. In this case, the providing device 30 may notify the user of the fact that the authentication has failed.

[0041] On the other hand, if the authentication is successful (YES in step S3), the providing unit 13 provides a service in the transportation facility according to the first user (step S5) and ends the process. Here, the providing unit 13 may provide a specific service based on the user information of the first user stored in the user DB 601, for example. The specific service may include, for example, discounts on various fees, opening of the entrance gate, etc.

[0042] (Example of giving a special benefit to a second user according to a first user) When the authentication by the authentication unit 12 is successful, the provision unit 13 may grant a benefit to the second user according to the first user. In this case, the provision unit 13 may determine that the greater the benefit to be granted to the second user, the greater the degree of physical disability of the first user. Thereby, for example, the greater the difficulty of assistance by a companion, the more preferential the benefit can be granted to the companion.

[0043] Furthermore, the providing unit 13 may determine, for example, that the higher the importance of the first user is, the greater the privilege to be granted to the second user. In this case, the providing unit 13 may determine, for example, that the higher the importance of the first user is, the higher at least one of the amount of annual membership fee paid by the first user for a specific service such as a means of transportation, the frequency of use, the amount of use within a specific period (e.g., the most recent year), and the amount of payment if the current authentication is successful. This can further motivate the accompanying person to help the person who requires assistance, for example, when the person is an important customer for a company.

[0044] (Example of giving a benefit to a first user according to a second user) When the authentication by the authentication unit 12 is successful, the provision unit 13 may grant a benefit to the first user according to the second user. In this case, the provision unit 13 may determine that the greater the benefit to be granted to the first user, the greater the proficiency of the second user in accompanying a person. It is considered that a more skilled companion can more smoothly perform operations such as deactivating the gate proxy and issuing a ticket on behalf of the person. Therefore, by providing a motivation for the person requiring assistance to select a companion with a higher proficiency, it is expected that the companion can become more skilled.

[0045] In this case, the providing unit 13 may determine the second user's accompaniment proficiency to be higher, for example, the higher the frequency with which the second user accompanies a person requiring assistance, etc. Also, the providing unit 13 may determine the second user's accompaniment proficiency to be higher, for example, the higher the evaluation of the second user in a questionnaire given by the person requiring assistance, etc., accompanied by the second user.

[0046] (Example of using decentralized ID) The information processing system 1 may use a mechanism of a decentralized identity (Decentralized Identity) instead of or in addition to the configuration of recording data on the second user (companion, etc.) in the companion DB 501 and recording data on the first user in the user DB 601. The decentralized identity may be, for example, a decentralized identity positioned in web3 using a block chain technology or the like, or a decentralized identity for reducing information stored in a central database.

[0047] In this case, data of the first user may be recorded in a user terminal 20 such as a smartphone or a blockchain, and data of the second user may be recorded in a terminal of a second user such as a smartphone or a blockchain. The information processing device 10 may then be able to acquire each piece of data as necessary. This allows, for example, the user to control the data provided to the information processing device 10 by himself / herself.

[0048] <Modification> The information processing device 10 may be a device contained in one housing, but the information processing device 10 of the present disclosure is not limited to this. Each unit of the information processing device 10 may be realized by cloud computing configured by one or more computers, for example. In addition, the information processing device 10 and the providing device 30 may be housed in the same housing and configured as an integrated information processing device. In addition, at least a part of the processing of each functional unit of the information processing device 10 may be executed by at least one of the user terminal 20 and the providing device 30. Such information processing devices 10 are also included in examples of the "information processing device" of the present disclosure.

[0049] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above-mentioned embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
