Description

[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and a program. [Background technology]

[0002] Currently, systems using biometric authentication are widely used. Known biometric authentication methods include one-to-one authentication, which requires the input of a user ID, and one-to-N authentication, which does not require the input of a user ID and identifies the user ID on the server side based on biometric authentication. For example, Patent Document 1 discloses a one-to-N authentication system and method that are fast and have few errors. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-244511 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when performing biometric authentication, it is necessary to have the user enter a user ID or to identify the user ID based on biometric information. Also, since the user uses the user ID consciously, it is necessary to limit the number of digits to a certain extent while considering the balance with convenience. Therefore, there is an issue that the number of users that can be registered in the system is limited by the number of possible user IDs.

[0005] Therefore, an object of the present invention is to provide a technique that can prevent user registration and authentication from becoming complicated. [Means for solving the problem]

[0006] An information processing device according to one aspect of the present invention includes a memory unit that stores management information in which user identification information generated from a user's biometric information is associated with the user information of the user; an acquisition unit that acquires the biometric information of a first user; a generation unit that generates first user identification information from the biometric information of the first user; a matching unit that checks whether the first user identification information corresponds to the user identification information included in the management information; and a processing unit that, if the first user identification information corresponds to the user identification information, acquires the user information associated with the user identification information from the management information and performs processing based on the user information. [Effects of the Invention]

[0007] According to the present invention, it is possible to prevent user registration and authentication from becoming complicated. [Brief explanation of the drawings]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings, in which the same reference numerals denote the same or similar components.

[0010] <System configuration> Fig. 1 is a diagram showing an example of the configuration of an information processing system according to this embodiment. As shown in Fig. 1, the information processing system 1 includes an information processing device 10, one or more user terminals 20, one or more service reception devices 30, and one or more service providing devices 40. The information processing device 10 provides an authentication infrastructure using biometric information for various services provided by the service providing device 40.

[0011] The information processing device 10 calculates user identification information from the user's biometric information and uses the calculated user identification information as a user ID (Identifier). It also identifies the service used by the user and stores the information necessary for using the service (hereinafter referred to as "service usage information") in association with the service in a database. The user identification information may be called a template. The information processing device 10 may be configured using one or more physical servers, or may be configured using a virtual server operating on a hypervisor, or may be configured using a cloud server.

[0012] The user terminal 20 is a device used by a user, such as a smartphone, a tablet terminal, or a personal computer.

[0013] The service reception device 30 is a device that accepts use of a service provided by the service providing device 40. Examples of the service reception device 30 include, but are not limited to, a POS (Point Of Sales) terminal installed in a store or the like, a parking fee collection system, a public power supply spot, a fee collection system for a toll road or the like, an information terminal in a city or facility, etc. Any device may be used as long as it accepts use of a service provided by the service providing device 40.

[0014] The service providing device 40 is a device that provides a service to a user. The services provided by the service providing device 40 include any services, such as a payment service, a point service, a parking service, a charging service, and an information providing service.

[0015] When the information processing device 10 acquires biometric information of a user from the user terminal 20 or the service reception device 30, it generates user identification information from the acquired biometric information and compares the generated user identification information with one or more pieces of user identification information registered in a database. If the result of the comparison is that one piece of matching user identification information exists, the information processing device 10 provides the user with a service associated with the user identification information.

[0016] In conventional technology, it is common to associate and manage user IDs and templates used for biometric authentication, and then have the user input the user ID before biometric authentication, or identify the user ID from biometric information acquired from the user before providing a service. On the other hand, in this embodiment, the information processing device 10 uses the user identification information as the user ID as is, so there is no need to have the user input the user ID or identify the user ID when verifying (authenticating) the biometric information. This makes it possible to prevent user registration and authentication from becoming complicated.

[0017] <Hardware configuration> 2 is a diagram illustrating an example of the hardware configuration of the information processing device 10, the user terminal 20, the service reception device 30, and the service providing device 40. The information processing device 10, the user terminal 20, the service reception device 30, and the service providing device 40 each include a processor 11 such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), a memory (e.g., RAM (Random Access Memory) or ROM (Read Only Memory)), a storage device 12 such as an HDD (Hard Disk Drive) and / or an SSD (Solid State Drive), a communication IF (Interface) 13 for wired or wireless communication, an input device 14 for accepting input operations, and an output device 15 for outputting information. The input device 14 is, for example, a keyboard, a touch panel, a mouse, and / or a microphone. The output device 15 is, for example, a display, a touch panel, and / or a speaker.

[0018] <Function block configuration> (Information processing device) FIG. 3 is a diagram illustrating an example of a functional block configuration of the information processing device 10. The information processing device 10 includes a storage unit 100, an acquisition unit 101, a generation unit 102, a management unit 103, a collation unit 104, and a processing unit 105. The storage unit 100 can be implemented using a storage device 12 included in the information processing device 10. The acquisition unit 101, the generation unit 102, the management unit 103, the collation unit 104, and the processing unit 105 can be implemented by the processor 11 of the information processing device 10 executing a program stored in the storage device 12. The program can be stored in a storage medium. The storage medium storing the program may be a non-transitory computer-readable medium. The non-transitory storage medium is not particularly limited, and may be, for example, a storage medium such as a universal serial bus (USB) memory or a compact disc read-only memory (CD-ROM).

[0019] The storage unit 100 stores management information 100a in which user information is associated with user identification information generated from the user's biometric information. The user information may include service usage information related to services used by the user.

[0020] FIG. 4 is a diagram illustrating an example of management information 100a. Management information 100a manages user identification information and user information in association with each other. The user information includes "user-specific information," which is the user's name, address, age, and / or various data related to the user, and "service usage information," which is information that uniquely identifies the service used by the user and is necessary for using the service. The service usage information may include, for example, the service name, information necessary for accessing the service providing device 40 (address information, protocol information, etc.), and information used by the service providing device 40 to provide the service (e.g., the user's account number, etc.). Furthermore, the user information may include multiple pieces of service usage information. For example, in the example of FIG. 4, the service usage information of Ichiro Sato includes service usage information for service A and service usage information for service B. Returning to FIG. 3, the explanation will be continued.

[0021] The acquisition unit 101 acquires biometric information and user information of a user who performs user registration. The acquisition unit 101 also acquires biometric information of the user (first user). For example, the acquisition unit 101 may acquire biometric information of the user to be matched (first user) from another information processing device (e.g., the user terminal 20 or the service reception device 30) that requests matching of user identification information.

[0022] The generating unit 102 generates user identification information from the biometric information of the user who performs user registration. The generating unit 102 also generates user identification information (first user identification information) from the biometric information of the user to be matched.

[0023] The management unit 103 associates the user identification information of the user who is performing user registration and the user information generated by the generation unit 102 and stores them in the management information 100a.

[0024] The verification unit 104 verifies whether the user identification information of the user to be verified, generated by the generation unit 102, corresponds to the user identification information included in the management information 100a.

[0025] When the user identification information of the user to be matched corresponds to the user identification information included in the management information 100a, the processing unit 105 acquires user information associated with the user identification information from the management information 100a and performs various processes based on the acquired user information. Also, when the user identification information of the user to be matched corresponds to the user identification information included in the management information 100a, the processing unit 105 performs processes related to various services used by the user based on service usage information associated with the user identification information.

[0026] (user terminal) FIG. 5 is a diagram showing an example of a functional block configuration of the user terminal 20. The user terminal 20 includes a storage unit 200, an acquisition unit 201, a transmission unit 202, and a reception unit 203. The storage unit 200 can be realized using the storage unit 12 provided in the user terminal 20. The acquisition unit 201, the transmission unit 202, and the reception unit 203 can be realized by the processor 11 of the user terminal 20 executing a program stored in the storage unit 12. The program can be stored in a storage medium. The storage medium storing the program may be a computer-readable non-transitory storage medium. The non-transitory storage medium is not particularly limited, and may be, for example, a storage medium such as a USB memory or a CD-ROM.

[0027] The storage unit 200 stores various types of information required for the user terminal 20 to perform the processing according to this embodiment.

[0028] The acquiring unit 201 acquires biometric information and user information from a user who is to perform user registration, and also acquires biometric information from a user to be matched.

[0029] The transmission unit 202 transmits the biometric information of the user who is to perform user registration and the user information to the information processing device 10. The transmission unit 202 also transmits the biometric information of the user to be verified to the information processing device 10.

[0030] The receiving unit 203 receives various data from the information processing device 10. For example, the receiving unit 203 receives from the information processing device 10 the result of matching the biometric information of the user, information on whether or not the service can be used, and the like.

[0031] The generating unit 204 generates user identification information from the biometric information of the user. Note that if the user identification information is generated on the information processing device 10 side, the user terminal 20 does not need to include the generating unit 204.

[0032] (Service reception device) FIG. 6 is a diagram showing an example of a functional block configuration of the service reception device 30. The service reception device 30 includes a storage unit 300, an acquisition unit 301, a transmission unit 302, and a reception unit 303. The storage unit 300 can be realized using the storage device 12 included in the service reception device 30. The acquisition unit 301, the transmission unit 302, and the reception unit 303 can be realized by the processor 11 of the user terminal 20 executing a program stored in the storage device 12. The program can be stored in a storage medium. The storage medium storing the program may be a computer-readable non-transitory storage medium. The non-transitory storage medium is not particularly limited, and may be, for example, a storage medium such as a USB memory or a CD-ROM.

[0033] The storage unit 300 stores various types of information required for the service reception device 30 to perform the processing according to this embodiment.

[0034] The acquiring unit 301 acquires biometric information and user information from a user who is to perform user registration, and also acquires biometric information from a user to be matched.

[0035] The transmission unit 302 transmits the biometric information of the user who is to perform user registration and the user information to the information processing device 10. The transmission unit 302 also transmits the biometric information of the user to be verified to the information processing device 10.

[0036] The receiving unit 303 receives various data from the information processing device 10. For example, the receiving unit 303 receives from the information processing device 10 the result of matching the user's biometric information, information regarding whether or not the service can be used, and the like.

[0037] The generating unit 304 generates user identification information from the biometric information of the user. Note that if the user identification information is generated on the information processing device 10 side, the service reception device 30 does not need to include the generating unit 304.

[0038] <Processing Procedure> (User registration) FIG. 7 is a sequence diagram showing an example of a processing procedure for performing user registration. In step S10, the acquisition unit 201 of the user terminal 20 acquires biometric information of the user who is to perform user registration. Examples of the biometric information include the user's appearance, face image, fingerprints, palm print, veins, voice, behavior, iris, eye blood vessels, ear shape, and DNA. The acquisition unit 201 also acquires user-specific information (such as name, age, address, and gender) from the user. The acquisition unit 201 also acquires service usage information for the service the user wishes to use, such as the service name, information required to access the service providing device 40 (such as address information and protocol information), and information used by the service providing device 40 to provide the service (such as the user's account number). Note that it is not essential to input the information required to access the service providing device 40. The information may be set in advance for each service in the information processing device 10.

[0039] In step S11, the transmitting unit 202 of the user terminal 20 transmits a registration request message to the information processing device 10. The registration request message includes the user's biometric information, user specific information, and service usage information input in the processing procedure of step S10.

[0040] In step S12, the acquisition unit 101 of the information processing device 10 receives a registration request message from the user terminal 20. The generation unit 102 generates user identification information from the biometric information included in the registration request message. The user identification information (the same applies to the first user identification information) may be, for example, a feature generated from the biometric information itself, or data obtained by processing the generated feature according to a predetermined method. The generation unit 102 may generate the user identification information using an API (Application Programming Interface) provided by a third party. The user identification information may be expressed as numerical data or text data. The user identification information may be all or a part of data obtained by converting the text data or binary data according to a predetermined method (for example, encryption or hashing).

[0041] In step S13, the management unit 103 sends a message to the user terminal 20 requesting personal identification data.

[0042] In step S14, the acquisition unit 201 of the user terminal 20 acquires personal identification data from the user. The transmission unit 202 transmits the acquired personal identification data to the information processing device 10. The personal identification data may be, for example, an image of a driver's license, student ID card, employee ID card, or the like, which contains the user's facial photograph and user-specific information (such as name and address).

[0043] In step S15, the management unit 103 performs identity verification of the user based on the identity verification data received from the user terminal 20. When the user registration shown in FIG. 7 is performed in a store, the processing procedures of steps S14 and S15 may be performed by a store clerk or the like at the store using a driver's license or the like. When the user registration shown in FIG. 7 is performed online, the processing procedures of steps S14 and S15 may be performed automatically or by an administrator or the like according to a method called eKYC (electronic Know Your Customer). The identity verification of the user may also be performed by using public personal authentication, verifying a certificate using a digital identity wallet (DIW), electronic certificate data, a digital driver's license, a digital student ID, a digital employee ID, or the like, or by verifying user attribute information or user employment status with a financial institution or other institution.

[0044] In step S16, if the user identity verification is completed, the management unit 103 stores the user identification information, user specific information, and service usage information in the management information 100a. On the other hand, if the user identity verification is not completed, the management unit 103 ends the process without storing the user identification information, etc. in the management information 100a.

[0045] In step S17, the management unit 103 transmits a registration completion message to the user terminal 20.

[0046] When user registration is performed at a store or the like, the above-described processing procedure may be executed by the service reception device 30 instead of the user terminal 20.

[0047] Furthermore, the process of generating user identification information from the user's biometric information may be executed by the generation unit 204 of the user terminal 20. The method of generating the user identification information may be the same as the method described in the processing procedure of step S12. In this case, the transmission unit 202 may transmit the user identification information to the information processing device 10 instead of the biometric information in the processing procedure of step S11.

[0048] Furthermore, if the user's identity verification data includes biometric information, in the processing procedure of step S11, the user terminal 20 may transmit identity verification data including the biometric information (or the biometric information and the user-specific information). Furthermore, the acquisition unit 101 of the information processing device 10 may acquire the user's biometric information (or the biometric information and the user-specific information) included in the identity verification data. Furthermore, in the processing procedure of step S12, the generation unit 102 may generate user identification information from the biometric information included in the identity verification data. Furthermore, in the processing procedure of step S16, the management unit 103 may store the user identification information, the user-specific information, and the service usage information generated from the biometric information included in the identity verification data in the management information 100a. Furthermore, the processing procedures of steps S13 and S14 may be omitted. The generated information included in the identity verification data is arbitrary, and examples thereof include a facial photograph on an official document (such as a driver's license or a My Number card), biometric information recorded on an IC chip, and biometric information obtainable from a DIW.

[0049] Furthermore, in this embodiment, in addition to matching biometric information, user possession authentication, knowledge authentication, etc. may be performed. In this case, the acquisition unit 101 of the user terminal 20 may acquire information about the device used for possession authentication (for example, the telephone number and email address of the user terminal 20) and information used for knowledge authentication (such as a personal identification number and password) from the user, and transmit these to the information processing device 10. Furthermore, the management unit 103 of the information processing device 10 may register the acquired information about the device used for possession authentication and information used for knowledge authentication in "user information" of the management information 100a.

[0050] (Service Use) Fig. 8 is a sequence diagram showing an example of a processing procedure when using a registered service. The processing procedure shown in Fig. 8 is assumed to be a case where a user uses a service registered at the time of user registration at a store or the like, but is not necessarily limited to this. For example, it can also be applied to a case where a service is used remotely using a user terminal 20. In this case, it can be realized by replacing the service reception device 30 with the user terminal 20 in the sequence of Fig. 8.

[0051] In step S20, the acquisition unit 301 of the service reception device 30 acquires biometric information of a user (user to be verified) who wishes to use the service. Note that the acquired biometric information is assumed to be the same as the biometric information used by the user to be verified at the time of user registration.

[0052] In step S21, the transmitting unit 302 transmits the acquired biological information to the information processing device 10.

[0053] In step S22, the generation unit 102 of the information processing device 10 generates user identification information from the biometric information acquired from the service reception device 30. The method for generating the user identification information is the same as the processing procedure in step S12 of Fig. 7, and therefore description thereof will be omitted.

[0054] In step S23, the matching unit 104 matches the user identification information of the user to be matched, generated in step S22, with the "user identification information" included in the management information 100a. Specifically, the matching unit 104 sequentially matches whether or not "user identification information" corresponding to the user identification information of the user to be matched is present among one or more pieces of "user identification information" included in the management information 100a. An existing algorithm may be used to match the user identification information. For example, the matching unit 104 may match the user identification information by checking whether or not the range of fluctuation appearing in the user identification information generated from the biometric information is within a predetermined range.

[0055] Furthermore, the matching unit 104 may perform matching using a learning model that has been trained to have the ability to match the user identification information of the user to be matched with the user identification information included in the management information 100a. For example, the matching unit 104 may perform matching by inputting the user identification information of the user to be matched with each piece of user identification information registered in the management information 100a into the learning model. Furthermore, the matching unit 104 may perform matching of the user identification information using an API provided by a third party.

[0056] The matching unit 104 determines that the matching is successful if one or more pieces of "user identification information" included in the management information 100a contain one "user identification information" that corresponds to the user identification information of the user to be matched. On the other hand, if one or more pieces of "user identification information" included in the management information 100a do not contain "user identification information" that corresponds to the user identification information of the user to be matched, or if there are multiple pieces of "user identification information" included in the management information 100a, the matching unit 104 determines that the matching is unsuccessful.

[0057] In step S24, the checking unit 104 transmits the checking result of the user identification information to the service reception device 30.

[0058] If the matching of the user identification information is successful in step S25, the processing unit 105 executes processing related to the service specified by the "service usage information" associated with the matched "user identification information." For example, if the specified service is a payment service, the processing unit 105 may request the service providing device 40 of the payment business operator to confirm the validity of the user's account information and debit the payment amount from the user's account. On the other hand, if the matching of the user identification information fails, the processing related to the service is not executed.

[0059] In the processing procedure described above, if the information processing device 10 has successfully matched the biometric information, it may further perform user possession authentication or knowledge authentication, etc. For example, when performing possession authentication, the matching unit 104 may, after the processing procedure of step S23, use information about the device used for possession authentication to send authentication information (passcode) to the device. Furthermore, if the authentication information input by the user to the service reception device 30 matches the authentication information sent to the device used for possession authentication, the matching unit 104 may consider the matching of the user identification information to have been successful, and proceed to the processing procedure of step S24.

[0060] Furthermore, when knowledge-based authentication is performed, after the processing procedure of step S23, the matching unit 104 may inquire about information to be used for knowledge-based authentication from the user via the service reception device 30. Furthermore, when the information to be used for knowledge-based authentication input by the user to the service reception device 30 matches the information to be used for knowledge-based authentication stored in the management information 100a, the matching unit 104 may determine that matching of the user identification information has been successful, and proceed to the processing procedure of step S24.

[0061] (Variation) When the user identification information of the user to be matched corresponds to the user identification information included in the management information 100a, the processing unit 105 of the information processing device 10 may perform processing to inquire of the service reception device 30 (another information processing device) about selecting a service to process from among multiple pieces of "service usage information" included in the user information acquired from the management information 100a. Furthermore, the processing unit 105 may perform processing related to the service selected by the user in the service reception device 30. This makes it possible to associate multiple services with the user identification information and allow the user to select which service to use.

[0062] <Summary> According to the embodiment described above, the information processing device 10 uses user identification information generated from the user's biometric information as a user ID. This makes it possible to provide a technology that can prevent user registration and authentication from becoming complicated.
