[0013] In a first embodiment of the present disclosure, an information management system 100 that manages NFT biometric information in which any biometric information is associated with an NFT (non-fungible token) will be described. As will be described later, the information management system 100 in this embodiment stores the NFT biometric information in association with attribute information including a plurality of attributes. Furthermore, when the information management system 100 receives a usage request requesting the use of the NFT biometric information from an external device, it selects an attribute to be transmitted depending on the sender of the usage request, etc. Thereafter, the information management system 100 transmits the selected attribute and the NFT biometric information to the sender of the usage request.

[0014] In this embodiment, biometric information refers to information corresponding to a person's physical characteristics, behavioral characteristics, etc. For example, the biometric information can include at least one of facial features calculated based on a person's face image, fingerprint features corresponding to minutiae extracted from a finger image, iris features corresponding to iris patterns, and vein features corresponding to vein patterns on the palm or fingers. The biometric information may also include features corresponding to behavioral characteristics such as walking habits.

[0015] NFTs are non-fungible tokens that are issued and traded on a blockchain. Documents describing NFTs include, for example, Patent Document 2.

[0016] The attribute information includes multiple pieces of information indicating attributes of individuals and groups to which individuals belong. Here, the attribute in this embodiment refers to identification information such as numbers privately or publicly assigned to individuals or groups to which individuals belong, such as My Number, pension number, employee number, credit card number, or various membership card numbers. The attribute may include information other than the above examples.

[0017] Fig. 1 shows an example configuration of an information management system 100. Referring to Fig. 1, the information management system 100 includes, for example, an information management device 200, a user device 300, an NFT market 400, and a personal terminal 500. For example, as shown in Fig. 1, the information management system 100 includes a plurality of user devices 300 and a plurality of personal terminals 500. The information management system 100 may also include a plurality of information management devices 200 and a plurality of NFT markets 400.

[0018] As shown in FIG. 1, the information management device 200 and the user device 300 can be connected to each other via any network or the like so that they can communicate with each other. Furthermore, the information management device 200 and the NFT market 400 can be connected to each other via any network or the like so that they can communicate with each other. Furthermore, the information management device 200 and the personal terminal 500 can be connected to each other via any network or the like so that they can communicate with each other. Furthermore, the NFT market 400 and the personal terminal 500 can be connected to each other via any network or the like so that they can communicate with each other.

[0019] The information management device 200 is an information processing device that manages NFT biometric information and attribute information in association with each other. Fig. 2 shows an example configuration of the information management device 200. Referring to Fig. 2, the information management device 200 has, as main components, for example, an operation input unit 210, a screen display unit 220, a communication I / F unit 230, a storage unit 240, and an arithmetic processing unit 250.

[0020] 2 illustrates an example in which the functions of the information management device 200 are realized using one information processing device. However, the information management device 200 may be realized using a plurality of information processing devices, for example, on the cloud. For example, the information management device 200 may be realized by a plurality of information processing devices having some of the functions illustrated in FIG. 2. Furthermore, the information management device 200 may not have some of the configurations illustrated above, such as not having the operation input unit 210, or may have a configuration other than those illustrated above.

[0021] The operation input unit 210 is made up of operation input devices such as a keyboard, a mouse, etc. The operation input unit 210 detects the operation of the person operating the information management device 200 and outputs the operation to the arithmetic processing unit 250.

[0022] The screen display unit 220 is composed of a screen display device such as an LCD (Liquid Crystal Display). The screen display unit 220 can display various information stored in the storage unit 240 on the screen in response to instructions from the arithmetic processing unit 250.

[0023] The communication I / F unit 230 is made up of a data communication circuit and performs data communication with an external device connected via a communication line.

[0024] The storage unit 240 is a storage device such as a hard disk or memory. The storage unit 240 stores processing information and programs 242 required for various processes in the arithmetic processing unit 250. The programs 242 are read into the arithmetic processing unit 250 and executed to realize various processing units. The programs 242 are read in advance from an external device or recording medium via a data input / output function such as the communication I / F unit 230, and are stored in the storage unit 240. Main information stored in the storage unit 240 includes, for example, management information 241.

[0025] The management information 241 includes NFT biometric information, attribute information, etc. For example, the management information 241 is generated and updated when the registration acceptance unit 251 accepts registration of NFT biometric information, etc. The management information 241 may also be updated at any other timing, such as in response to an instruction from the personal terminal 500. For example, part of the information included in the management information 241 may be acquired and updated from the NFT market 400, etc., when transmitting NFT biometric information, attribute information, etc. to the user device 300, etc., in response to a usage request.

[0026] FIG. 3 shows an example of information included in the management information 241. Referring to FIG. 3, the management information 241 includes, for example, NFT biometric information and attribute information. Here, the NFT biometric information can include identification information for identifying the NFT and biometric information. For example, the identification information is information for identifying the NFT, such as the address of the corresponding NFT on the blockchain or the NFT's ID (identification). Furthermore, the biometric information includes, for example, at least one of facial features, fingerprint features, iris features, and vein features. The identification information and biometric information included in the NFT biometric information may be other than those exemplified. Furthermore, the attribute information includes multiple attributes. For example, the attributes may be identification information such as numbers privately or publicly assigned to individuals or groups to which individuals belong, such as My Number, pension number, employee number, credit card number, or various membership card numbers. The attributes may be other than those exemplified.

[0027] FIG. 3 shows an example of information included in the management information 241. The management information 241 may include some of the information exemplified in FIG. 3, or may include information other than that exemplified in FIG. 3. For example, FIG. 4 shows another example of information included in the management information 241. Referring to FIG. 4, the management information 241 may include license information in addition to the NFT biometric information and attribute information. Here, the license information is information indicating the scope of permission for use of the NFT biometric information. For example, the license information may include information indicating the scope of permission, such as licensee information indicating the licensee who grants permission to use the NFT biometric information and use information indicating the purpose for which use of the NFT biometric information is permitted. The license information may also include information indicating the scope of permission other than that exemplified above. The management information 241 may also include information other than that exemplified in this embodiment, such as expiration information indicating the expiration date of the NFT biometric information or the license information, and specific information for identifying the person who owns the NFT biometric information, such as their address or age.

[0028] The arithmetic processing unit 250 has an arithmetic device such as a CPU (Central Processing Unit) and its peripheral circuits. The arithmetic processing unit 250 reads and executes a program 242 from the storage unit 240, thereby realizing various processing functions by causing the above hardware and the program 242 to work together. Major processing units realized by the arithmetic processing unit 250 include, for example, a registration receiving unit 251, a request receiving unit 252, a selection unit 253, a data transmission unit 254, and a fee management unit 255.

[0029] The registration reception unit 251 accepts registration of NFT biometric information and attribute information. For example, the registration reception unit 251 accepts registration of NFT biometric information, attribute information, etc. from the personal terminal 500, etc., via the communication I / F unit 230. In addition, the registration reception unit 251 stores the accepted NFT biometric information, attribute information, etc. in the storage unit 240 as management information 241.

[0030] The registration acceptance unit 251 may receive other information such as permission information, expiration date information, and specific information from the personal terminal 500 or the like when accepting registration or after accepting registration. The registration acceptance unit 251 can store the accepted various information in the storage unit 240 as management information 241. Furthermore, the registration acceptance unit 251 may acquire part of the information included in the NFT biometric information from the NFT market 400 or the like when accepting registration, after accepting registration, or when receiving a usage request. Furthermore, the registration acceptance unit 251 may be configured to notify the NFT market 400 or the like that the registration of the NFT biometric information has been accepted when accepting registration from the personal terminal 500 or the like.

[0031] The request receiving unit 252 receives a usage request requesting the use of NFT biometric information, etc. For example, the request receiving unit 252 receives a usage request from the user device 300, etc., via the communication I / F unit 230. The usage request received by the request receiving unit 252 may include information for identifying the sender of the usage request, such as identification information predetermined for each user device 300, information indicating the use of the NFT biometric information, information for specifying the range of requested transmission, such as age and address, and information indicating attributes requested to be transmitted. The usage request may include information other than the above examples.

[0032] The selection unit 253 selects an attribute to be transmitted in response to a usage request from among the attributes included in the attribute information. For example, the selection unit 253 selects an attribute to be transmitted in response to the received usage request when the request reception unit 252 receives the usage request. The selection unit 253 may select an attribute at a timing other than the above example, such as when the fee management unit 255, which will be described later, receives payment of a usage fee.

[0033] For example, the selection unit 253 can select an attribute to be transmitted depending on the sender of the usage request, etc. As an example, the selection unit 253 accepts registration in advance of information indicating the attribute to be used for each user device 300. Based on the information, the selection unit 253 can select an attribute corresponding to the user device 300 that is the sender of the usage request. For example, when the sender of the usage request is a government agency, the selection unit 253 can be configured to select a predetermined attribute depending on the sender, such as a pension number or My Number.

[0034] The selection unit 253 may also select attributes using a method other than those exemplified above. For example, the selection unit 253 may select attributes based on information indicating the attributes requested to be transmitted, received along with the usage request. The selection unit 253 may also select attributes according to the intended use, for example, based on information indicating the intended use. The attributes for each intended use may be predetermined, for example, or may be configured to be determined by any method. The selection unit 253 may select attributes by combining the methods exemplified above, for example, by narrowing down the attributes to be selected based on the sender and then specifying the attributes according to the intended use. The selection unit 253 may also be configured to select only one attribute from the attributes included in the attribute information, or may be configured to be able to select multiple attributes.

[0035] In response to the usage request, the data transmission unit 254 transmits the NFT biometric information and the attribute selected by the selection unit 253 to the sender of the usage request. In cases where the usage request includes information for specifying the range of the transmission request, the data transmission unit 254 may be configured to transmit the NFT biometric information and attribute specified by the information.

[0036] The data transmission by the data transmission unit 254 may be configured to be performed on the condition that the fee management unit 255, which will be described later, receives payment of the usage fee from the user device 300. Furthermore, if the management information 241 includes permission information, the data transmission unit 254 may be configured to transmit, to the sender of the usage request, only NFT biometric information that has been previously authorized to be transmitted to the sender of the usage request. In this way, the data transmission unit 254 may be configured to transmit at least a portion of the NFT biometric information it manages based on predetermined information.

[0037] Furthermore, the data transmission unit 254 may be configured to notify the NFT market 400 after or before transmitting the data that the data will be transmitted (the data will be used). For example, the data transmission unit 254 may send the above notification together with information for identifying the NFT biometric information transmitted to the user device 300.

[0038] The fee management unit 255 manages the usage fees when using NFT biometric information.

[0039] For example, when the request receiving unit 252 receives a usage request, the fee management unit 255 accepts payment of a usage fee from the sender of the usage request, such as the user device 300. In response to accepting the usage fee, the fee management unit 255 may instruct the data sending unit 254 to send NFT transmission information.

[0040] Furthermore, when the fee management unit 255 receives a usage fee from the user device 300 or the like, it can pay the usage fee for the NFT biometric information to the NFT market 400. At this time, the fee management unit 255 may deduct an optional handling fee from the received usage fee and pay the amount to the NFT market 400 as the usage fee for the NFT biometric information. Note that, as will be described later, the NFT market 400 can pay the usage fee for the NFT biometric information to the personal terminal 500 in response to payment from the fee management unit 255. Therefore, the fee management unit 255 can also pay the usage fee to the personal terminal 500 via the NFT market 400.

[0041] The user device 300 is an information processing device that transmits a usage request requesting the use of NFT biometric information to the information management device 200. The user device 300 is, for example, a personal computer owned by any organization such as a government or a company. The functions of the user device 300 may be realized, for example, on the cloud. The user device 300 may be owned by a user other than those exemplified above.

[0042] Fig. 5 shows an example of a configuration characteristic of this embodiment that the user device 300 has. Referring to Fig. 5, for example, the user device 300 has a transmitting unit 310, a receiving unit 320, and a management unit 330. For example, the user device 300 has a calculation device such as a CPU and a storage device. The user device 300 can realize each of the above processing units by having the calculation device execute a program stored in the storage device.

[0043] The transmission unit 310 transmits a usage request to the information management device 200 in response to an operation by an operator or the like operating the user device 300. The transmission unit 310 may transmit at least some of the information for identifying the sender of the usage request, information indicating the use of the NFT biometric information, information for identifying the range of requested transmission such as age and address, information indicating attributes requested to be transmitted, etc., together with the usage request. The transmission unit 310 may also transmit information other than the above examples together with the usage request.

[0044] Furthermore, when transmitting the usage request, or before or after the transmission, the transmission unit 310 can pay a predetermined usage fee to the information management device 200. An existing system for paying the fee may be used.

[0045] The receiving unit 320 receives the NFT biometric information and attribute information from the information management device 200. For example, the receiving unit 320 receives from the information management device 200 the NFT biometric information and attribute information that the information management device 200 transmits in response to the usage request transmitted by the transmitting unit 310.

[0046] The management unit 330 stores and manages the NFT biometric information and attribute information received by the receiving unit 320 in a storage device. The management unit 330 can manage the NFT biometric information and attribute information so that the operator operating the user device 300 cannot view at least a portion of the NFT biometric information and attribute information stored in the storage device. In other words, the management unit 330 can make the received NFT biometric information and attribute information available on predetermined software, while managing them as a black box so that they cannot be displayed or output to an external device.

[0047] The NFT market 400 has a blockchain implemented by multiple information processing devices, and issues and trades NFTs on the blockchain. The NFT market 400 may be similar to an existing system for handling NFTs.

[0048] For example, the NFT market 400 issues an NFT corresponding to biometric information in response to a request from the personal terminal 500. The NFT market 400 also manages notifications from the information management device 200, the personal terminal 500, etc. on the blockchain. When the NFT market 400 receives a notification from the information management device 200 that data will be transmitted, the NFT market 400 may send a predetermined notification to the information management device 200 and the personal terminal 500, such as notifying the personal terminal 500 that the biometric information will be used.

[0049] Furthermore, when the NFT market 400 accepts payment of a usage fee from the information management device 200, it can pay a predetermined usage fee to the corresponding personal terminal 500. In this case, the NFT market 400 may pay the amount, minus an arbitrary handling fee, to the personal terminal 500 as the usage fee.

[0050] The personal terminal 500 is an information processing device owned by a person who uses biometric information. For example, the personal terminal 500 may be an existing information processing device such as a personal computer, a tablet, or a smartphone.

[0051] For example, the personal terminal 500 can request the NFT market 400 to issue an NFT corresponding to the biometric information in response to an operation by the operator operating the personal terminal 500. The biometric information may be acquired by any means, such as by an external device or the personal terminal 500 calculating the information based on image data acquired using an imaging device such as a camera included in the personal terminal 500. Furthermore, the personal terminal 500 can request the information management device 200 to register the NFT biometric information and attribute information in response to an operation by the operator operating the personal terminal 500. Furthermore, the personal terminal 500 can receive payment of usage fees and various notifications from the NFT market 400, etc.

[0052] The above is an example of the configuration of the information management system 100. Next, an example of the operation of the information management device 200 will be described with reference to FIGS.

[0053] First, an example of the operation of the information management device 200 at the time of registration will be described with reference to Fig. 6. Referring to Fig. 6, the registration reception unit 251 receives NFT biometric information, attribute information, etc. from the personal terminal 500 or the like via the communication I / F unit 230 (step S101). In response to reception from the personal terminal 500 or the like, the registration reception unit 251 may acquire part of the NFT biometric information, etc. from the NFT market 400 or the like.

[0054] The registration acceptance unit 251 may receive other information such as permission information, time limit information, and specific information from the personal terminal 500 when accepting the registration or after accepting the registration.

[0055] The registration acceptance unit 251 associates the received information and stores it in the storage unit 240 as management information 241 (step S102). Note that when the registration acceptance unit 251 accepts registration from the personal terminal 500 or the like, it may notify the NFT market 400 or the like that it has accepted the registration of the NFT biometric information.

[0056] The above is an example of the operation of the information management device 200 during registration. Next, an example of the operation of the information management device 200 during use will be described with reference to FIG.

[0057] Referring to FIG. 7, the request receiving unit 252 receives a usage request for requesting the use of NFT biometric information or the like from the user device 300 or the like (step S201).

[0058] The selection unit 253 selects an attribute to be transmitted in response to the usage request from among the attributes included in the attribute information (step S202). For example, the selection unit 253 selects an attribute to be transmitted in response to the source of the usage request, etc. The selection unit 253 may select an attribute in a manner other than the above example, such as selecting an attribute in response to information received together with the usage request.

[0059] The fee management unit 255 accepts payment of the usage fee from the sender of the usage request (step S203). Note that the processing of step S203 may be performed at a timing other than that illustrated in FIG. 7, such as before step S202.

[0060] When the fee management unit 255 accepts payment of the usage fee (step S203, Yes), the data transmission unit 254 transmits the NFT biometric information and the attributes selected by the selection unit 253 to the sender of the usage request in response to the usage request (step S204). The data transmission unit 254 may be configured to transmit only a portion of the information it manages, such as transmitting only the NFT biometric information identified based on the information received together with the usage request.

[0061] The fee management unit 255 pays the usage fee for the NFT biometric information to the NFT market 400 (step S205). At this time, the fee management unit 255 may deduct an optional handling fee from the accepted usage fee and pay the amount as the usage fee for the NFT biometric information to the NFT market 400. Note that the processing of step S205 may be performed at any timing after step S203.

[0062] The above is an example of the operation of the information management device 200 during use.

[0063] As described above, the information management device 200 has a request receiving unit 252 and a data transmitting unit 254. With this configuration, the data transmitting unit 254 can transmit at least a portion of the NFT biometric information and attribute information managed by the device itself to the sender of the usage request in response to the usage request received by the request receiving unit 252. This makes it possible to obtain the necessary NFT biometric information and attributes as needed, reducing the effort required when utilizing the biometric information.

[0064] The information management device 200 also has a selection unit 253. With this configuration, the data transmission unit 254 can transmit the attributes selected by the selection unit 253 along with the NFT biometric information. This makes it possible to transmit only appropriate attributes according to the sender of the usage request, etc., to the sender of the usage request, thereby reducing the effort required to more appropriately utilize biometric information.

[0065] The information management device 200 also has a fee management unit 255. With this configuration, the fee management unit 255 can pay a usage fee to the personal terminal 500 via the NFT market 400. As a result, an appropriate usage fee can be paid to the personal terminal 500 when utilizing biometric information, for example. In addition, as explained in this embodiment, because the usage fee is paid to the personal terminal 500 via the NFT market 400, the information management device 200 does not need to have a configuration for directly paying the usage fee to the personal terminal 500.

[0066] In this embodiment, the information management device 200 stores, as biometric information, feature amounts calculated based on image data or the like. That is, the example shows a case where an NFT corresponds to biometric information such as feature amounts. However, the information management device 200 may acquire and store image data such as a face image or a fingerprint image from the personal terminal 500 or the like instead of or together with the feature amounts. That is, an NFT may be associated with biometric information such as image data as NFT biometric information.

[0067] 8 shows an example of the configuration of the information management device 200 when storing image data. Referring to FIG. 8, the storage unit 240 stores image management information 243 instead of management information 241.

[0068] The image management information 243 can include at least a portion of the NFT biometric information, attribute information, etc., similar to the management information 241 illustrated in Fig. 3. The image management information 243 also includes image data such as a facial image as biometric information, along with or instead of the feature amount.

[0069] Also, referring to Figure 8, the calculation processing unit 250 can realize a calculation unit 256 in addition to a registration reception unit 251, a request reception unit 252, a selection unit 253, a data transmission unit 254, a fee management unit 255, etc., by reading and executing the program 242 from the memory unit 240.

[0070] The calculation unit 256 calculates the feature amount based on the image data. The calculation unit 256 can calculate the feature amount using a known method, such as extracting feature points such as eyes and nose from face image data and calculating the feature amount based on the extracted feature points. For example, in response to the request receiving unit 252 receiving a use request, the calculation unit 256 can calculate the feature amount using a method depending on the sender of the use request.

[0071] In this way, the information management device 200 can have a calculation unit 256. With this configuration, the data transmission unit 254 can transmit NFT biometric information including a feature calculated by a method according to the sender of the use request to the sender of the use request. This allows the sender of the use request to reliably use the biometric information, for example, and reduces the risk that the biometric information transmitted by the sender of the use request, etc., cannot be used due to differences in the calculation method of the feature. Note that the information management device 200 may be configured to transmit image data, etc., as is. In this case, the function of the calculation unit 256 may be provided by the user device 300, etc.

[0072] Furthermore, in this embodiment, an example has been given of the case where the information management system 100 has the information management device 200 and the NFT market 400 separately. However, in the information management system 100, the information management device 200 and the NFT market 400 may be configured as an integrated unit, as exemplified in Figure 9. In this way, even when the information management device 200 and the NFT market 400 are configured as an integrated unit, the object of the present invention can be achieved in the same way as in the case described above.

[0073] The present invention can be utilized, for example, when providing various services using biometric information, such as when local governments and other administrative bodies use biometric information such as facial recognition to control boarding on buses and other means of transportation. For example, the present invention may also be utilized when companies and other organizations provide services related to the metaverse (virtual world), such as when holding digital concerts. For example, applying the present invention when providing services related to the metaverse makes it possible to reliably prove that a person actually existed in the virtual world. In other words, utilizing the present invention when a provider of a metaverse-related service provides a service by functioning as a user device 300 can appropriately prevent impersonation in the virtual world.

[0074] [Second embodiment] Next, a second embodiment of the present disclosure will be described with reference to Fig. 10 and Fig. 11. In the second embodiment of the present disclosure, an overview of the configuration of an information management device 600, which is an information processing device, will be described.

[0075] Fig. 10 shows an example of the hardware configuration of the information management device 600. Referring to Fig. 10, the information management device 600 has, as an example, the following hardware configuration. ·CPU (Central Processing Unit) 601 (computing unit) ROM (Read Only Memory) 602 (storage device) RAM (Random Access Memory) 603 (storage device) Programs 604 loaded into RAM 603 A storage device 605 for storing the programs 604 A drive device 606 that reads and writes from a recording medium 610 outside the information processing device A communication interface 607 for connecting to a communication network 611 outside the information processing device Input / output interface 608 for inputting and outputting data Bus 609 connecting each component

[0076] 11 by the CPU 601 acquiring and executing the program 604. The program group 604 is stored in advance in, for example, the storage device 605 or the ROM 602, and is loaded into the RAM 603 or the like by the CPU 601 for execution as needed. The program group 604 may be supplied to the CPU 601 via the communication network 611, or may be stored in advance in the recording medium 610, and the drive device 606 may read out the program and supply it to the CPU 601.

[0077] 11 shows an example of the hardware configuration of the information management device 600. The hardware configuration of the information management device 600 is not limited to the above-described case. For example, the information management device 600 may be configured with only a part of the above-described configuration, such as excluding the drive device 606.

[0078] The reception unit 621 receives, from an external device, a usage request requesting the use of NFT biometric information in which biometric information according to a person's characteristics is associated with a non-fungible token. As an example, the information management device 600 stores NFT biometric information in which biometric information is associated with a non-fungible token in a storage device included in the information management device 600. For example, the reception unit 621 receives, from an external device, a usage request requesting the use of NFT biometric information stored in the information management device 600.

[0079] The transmitting unit 622 transmits the NFT biometric information and the attributes of the person to the sender of the usage request based on the usage request received by the receiving unit 621. Note that the attributes are managed in association with the NFT biometric information by, for example, a storage device included in the information management device 600.

[0080] As described above, the information management device 600 has a reception unit 621 and a transmission unit 622. With this configuration, the transmission unit 622 can transmit the NFT biometric information and attributes to the sender of the usage request based on the usage request received by the reception unit 621. As a result, it is possible to transmit the necessary information in response to the usage request, thereby reducing the effort required to utilize the biometric information.

[0081] An information processing device such as the above-described information management device 600 can be realized by incorporating a predetermined program into the information processing device. Specifically, a program according to another aspect of the present invention is a program for realizing a process in which the information processing device receives, from an external device, a usage request requesting the information processing device to use NFT (non-fungible token) biometric information in which biometric information according to a person's characteristics is associated with a non-fungible token, and transmits, based on the received usage request, the NFT biometric information and the person's attributes that are managed in association with the NFT biometric information to the sender of the usage request.

[0082] In addition, the information management method executed by the above-mentioned information processing device is such that the information processing device receives from an external device a usage request requesting the use of NFT (non-fungible token) biometric information that associates biometric information corresponding to a person's characteristics with a non-fungible token, and based on the received usage request, transmits the NFT biometric information and the person's attributes that are managed in association with the NFT biometric information to the sender of the usage request.

[0083] Inventions such as a program (or recording medium) or an information management method having the above-described configuration have the same functions and effects as those described above, and can therefore achieve the above-described object of the present invention.
