Description

Technical Field

[0001] The present disclosure relates to a digital asset management device, a digital asset management system, a digital asset management method, and a non-transitory computer-readable medium.

Background Art

[0002] In recent years, transactions using digital assets in which the economic value of assets is expressed digitally have been conducted. Examples of digital assets include electronic money, Internet bank accounts, cryptocurrency, and accounts on social networking services (SNS).

[0003] Such digital assets have information stored in a digital format in a predetermined management server or the like. Therefore, when the owner of a digital asset dies or when it becomes difficult for the owner to manage it, the digital asset may not be managed. In the case of a paid membership service, the fee will continue to be charged until the cancellation procedure is completed. Further, even if the owner's family members or the like are aware of the existence of the digital asset, they may not be able to promptly take over the management of the asset because they do not know the ID or password.

[0004] In response to such problems, as a related technique, Patent Document 1 discloses an information processing apparatus including receiving means for transmitting confirmation information for confirming whether a user is alive to a user terminal and receiving response information to the confirmation information from the user terminal. When the information processing apparatus determines that no response information has been received within a certain period of time, it reads asset information and heir identification information from a storage unit based on the user's identification information, and includes control means for associating the asset information and the heir identification information and storing them in the storage unit. With such a configuration, the information processing apparatus disclosed in Patent Document 1 can read the location information of the heir and inquire whether to approve or abandon the inheritance. Further, when approval information indicating approval of the inquiry is received, processing related to the inheritance of the asset is executed for the heir.

Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted as necessary for clarity of explanation.

[0015] <Embodiment 1> Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a digital asset management apparatus 10 according to the present embodiment. The digital asset management apparatus 10 includes a registration unit 11, a first transmission unit 12, a second transmission unit 13, an authentication control unit 14, and an authorization unit 15.

[0016] The registration unit 11 registers the agent information of the agent with respect to the member information of the member having the account. If there is no access to the account for a period set by the member or longer, the first transmission unit 12 transmits a confirmation notice to the member. If there is no member response from the member to the confirmation notice, the second transmission unit 13 transmits an agent notice to the agent. When there is an agent response from the agent to the agent notice, the authentication control unit 14 controls the authentication of the agent. When the authentication is successful, the authorization unit 15 grants the agent the authority regarding the digital assets of the member.

[0017] FIG. 2 is a flowchart showing the flow of the digital asset management process performed by the digital asset management apparatus 10 according to the present embodiment. The registration unit 11 registers the agent information of the agent with respect to the member information of the member having the account (S11). The first transmission unit 12 determines whether there has been access to the account within the period set by the member (S12). If there has been access (YES in S12), the process ends. If there has been no access (NO in S12), the first transmission unit 12 transmits a confirmation notice to the member (S13).

[0018] The second transmission unit 13 determines whether there is a member response from the member to the confirmation notice (S14). If there is a member response (YES in S14), the process ends. If there is no member response (NO in S14), the second transmission unit 13 transmits an agent notice to the agent (S15).

[0019] The authentication control unit 14 determines whether there is an agent response from the agent to the agent notice (S16). If there is no agent response from the agent (NO in S16), the process ends. If there is an agent response (YES in S16), the authentication control unit 14 controls the authentication of the agent (S17). For example, the authentication control unit 14 requests an external authentication device to perform authentication using biometric authentication or a password and receives the authentication result.

[0020] The authority granting unit 15 determines whether the authentication of the agent is successful (S18). If the authentication fails (NO in S18), the process ends. If the authentication is successful (YES in S18), the authority granting unit 15 grants the agent the authority regarding the member's digital assets (S19).

[0021] As described above, in the digital asset management apparatus 10 according to the present embodiment, when there is no access to the account within the set period set by the member, a confirmation notice is sent to the member. If there is no response from the member, the digital asset management apparatus 10 sends an agent notice to the agent. When there is a response from the agent, the digital asset management apparatus 10 authenticates the agent, and when the agent succeeds in the authentication, the digital asset management apparatus 10 grants the agent the authority regarding the member's digital assets.

[0022] By doing so, even when the member has not accessed the account for more than the set period, the digital assets can be appropriately managed by granting the agent the authority.

[0023] <Embodiment 2> Subsequently, a configuration example of the digital asset management system 1000 according to Embodiment 2 will be described. This embodiment is a specific example of Embodiment 1 described above.

[0024] (Digital Asset Management System 1000) FIG. 3 is a block diagram showing the configuration of the digital asset management system 1000 according to the present embodiment. The digital asset management system 1000 includes an authentication device 100, a digital asset management device 200, a communication terminal 300, a communication terminal 301, and a communication terminal 302.

[0025] Each of the authentication device 100, the digital asset management device 200, the communication terminal 300, the communication terminal 301, and the communication terminal 302 is connected via a network N. The network N may be wired or wireless and may be of any communication protocol type.

[0026] The digital asset management system 1000 registers the agent information of an agent with respect to the member information of a member having an account, performs a predetermined determination process when there is no access by the member for a set period or more, and gives the agent the authority regarding digital assets. Digital assets can include, for example, electronic money, deposits in an Internet banking account, securities of online securities, or digital data such as characters, images, videos, music, etc. posted on SNS. Further, digital assets can include management information for managing these assets. The management information is, for example, an ID and password for logging in to a service for using digital assets. Therefore, for example, an ID and password for accessing an account such as an EC (Electronic Commerce) site used by a member can be included in the digital assets.

[0027] For example, assume that a member is regularly purchasing goods (such as supplements and cosmetics) on an EC site. If there is no access by the member to the EC site for a set period or more, authority is given to the agent according to a predetermined determination process. When the agent obtains the authority to acquire the ID and password for logging in to the EC site, the agent can use these to access the member's account. The agent stops the regular purchase of goods as necessary. By doing so, even in a case where payment is automatically made by bank account debit or the like, the use of the service can be stopped promptly. Note that the content of digital assets is not limited to these.

[0028] In this embodiment, the case where the agent information of agents B1 and B2 is registered with respect to the member information of member A1, who is a member of a service using digital assets, will be used for explanation. Here, the example where agents B1 and B2 are the spouse and child of member A1 respectively is used, but the relationship between the member and the agent is not limited. For example, a person without a blood relationship can be the agent. In the following, there are cases where agents B1 and B2 are collectively referred to simply as "agent" for explanation. Also, there are cases where member A1 is simply referred to as "member" for explanation.

[0029] (Communication terminals 300 to 302) The communication terminal 300 is a communication terminal owned by member A1. The communication terminal 300 is, for example, an information processing device such as a personal computer, a smartphone, or a tablet terminal. Without being limited thereto, various information processing devices capable of communicating via the network N may be used as the communication terminal 300. The communication terminal 300 includes a display unit 310. The display unit 310 is at least a display device. Further, the display unit 310 may be an input / output unit including a display device and an input device, for example, a touch panel. Member A1 registers member information and agent information in the digital asset management device 200 using the communication terminal 300 according to the registration screen 310a displayed on the display unit 310. The communication terminal 300 receives a confirmation notice or the like transmitted from the digital asset management device 200. Further, the communication terminal 300 makes a member response or the like to the confirmation notice to the digital asset management device 200.

[0030] The communication terminals 301 and 302 are communication terminals respectively owned by agents B1 and B2. The communication terminals 301 and 302 respectively include display units 311 and 312. Since the configurations of the communication terminals 301 and 302 are the same as those of the communication terminal 300, the description thereof is omitted. The communication terminals 301 and 302 receive agent notices or the like transmitted from the digital asset management device 200. Further, the communication terminals 301 and 302 make an agent response or the like to the agent notice to the digital asset management device 200. Furthermore, the communication terminals 301 and 302 receive an agent confirmation notice transmitted from the digital asset management device 200 and make a response thereto.

[0031] (Authentication device 100) The authentication device 100 is an information processing device that performs user authentication in response to an authentication request from the digital asset management device 200. Here, the user indicates member A1, agent B1, or agent B2. The authentication device 100 may perform authentication using an ID, password, etc., or may perform biometric authentication using biometric information such as a face or iris. The authentication device 100 returns the authentication result to the digital asset management device 200. Also, biometric authentication may be performed for some users. For example, password authentication may be performed for member A1, and biometric authentication may be performed for agents B1 or B2.

[0032] Hereinafter, taking the case where the authentication device 100 performs biometric authentication as an example, the configuration of the authentication device 100 will be specifically described. The authentication device 100 is an information processing device that, in response to a biometric authentication request received from the outside, collates the biometric information included in the request with the biometric information of each user stored in advance, and returns the collation result (authentication result) to the requester. Biometric information is the characteristic information of the biometric information used for biometric authentication. Biometric information is, for example, a face, voiceprint, fingerprint, iris, or vein, etc. Biometric information may use data (feature quantities) calculated from individual-specific physical characteristics such as a face or voiceprint as the characteristic information.

[0033] In this embodiment, it is assumed that the authentication device 100 performs face authentication of the user using the face characteristic information of the user as biometric information. The authentication device 100 receives a face authentication request together with the user's face image from the digital asset management device 200, and performs face authentication of the user. The authentication device 100 returns the authentication result to the digital asset management device 200 that is the requester.

[0034] FIG. 4 is a block diagram showing the configuration of the authentication device 100 according to this embodiment. The authentication device 100 includes a biometric information DB (DataBase) 110, a detection unit 120, a feature point extraction unit 130, a registration unit 140, and an authentication unit 150.

[0035] The biometric information DB 110 stores the user ID 111, the biometric characteristic information 112 of the user ID, and the biometric authentication method 113 in association with each other. User ID 111 is identification information for identifying a user. Biometric information 112 is a feature quantity calculated from physical characteristics unique to an individual user. In the present embodiment, the biometric information 112 is a set of feature points extracted from a face image of the user. Hereinafter, the biometric information 112 may be referred to as face feature information for explanation.

[0036] The biometric authentication method 113 is an authentication method such as face authentication, voiceprint authentication, and fingerprint authentication. In the present embodiment, the biometric authentication method 113 is face authentication. When the authentication device 100 performs biometric authentication of a plurality of authentication methods, the biometric authentication method 113 may include a plurality of different authentication methods. The authentication device 100 may perform biometric authentication using the biometric information 112 corresponding to the requested authentication method. Further, the authentication device 100 may perform authentication using a plurality of authentication methods according to a request.

[0037] The detection unit 120 detects a face area included in a registration image for registering face feature information and outputs it to the feature point extraction unit 130. The feature point extraction unit 130 extracts feature points from the face area detected by the detection unit 120 and outputs face feature information to the registration unit 140. Further, the feature point extraction unit 130 extracts feature points included in a face image or the like received from the digital asset management device 200 and outputs face feature information to the authentication unit 150.

[0038] When registering biometric information, the registration unit 140 newly issues a user ID 111. The registration unit 140 associates the issued user ID 111 with the biometric information 112 extracted from the registration image and registers it in the biometric information DB 110.

[0039] The authentication unit 150 performs biometric authentication using the biometric information 112. Specifically, the authentication unit 150 collates the face feature information extracted from the face image with the biometric information 112 in the biometric information DB 110. When the collation is successful, the authentication unit 150 identifies the user ID 111 associated with the collated biometric information 112.

[0040] The authentication unit 150 returns to the digital asset management device 200, as the result of biometric authentication, whether or not the biometric information matches. Whether or not the biometric information matches corresponds to the success or failure of the authentication. Note that the case where the biometric information matches (match exists) means that the degree of match is equal to or greater than a predetermined value. Also, the biometric authentication result shall include the specified user ID 111 when the biometric authentication is successful.

[0041] (Registration process of face information) Next, the registration process of face information according to this embodiment will be described. FIG. 5 is a flowchart showing the flow of the face information registration process according to this embodiment. First, the authentication device 100 acquires the registration image included in the face information registration request (S21). For example, the authentication device 100 receives a face information registration request from the digital asset management device 200, a registration web site, etc. via the network N.

[0042] Next, the detection unit 120 detects the face area included in the registration image (S22). Next, the feature point extraction unit 130 extracts feature points from the face area detected in step S22, and outputs biometric information (face feature information) 112 to the registration unit 140 (S23). Finally, the registration unit 140 issues a user ID 111, associates the user ID 111 with the biometric information 112, and registers them in the biometric information DB 110 (S24). The authentication device 100 may receive the biometric information 112 from a communication terminal or the like owned by the user, associate the biometric information 112 with the user ID 111, and register them in the biometric information DB 110.

[0043] (Face authentication process) Next, the flow of the face authentication process will be described. FIG. 6 is a flowchart showing the flow of the face authentication process by the authentication device 100 according to this embodiment.

[0044] First, the feature point extraction unit 130 acquires the face feature information included in the biometric authentication request (S31). For example, the authentication device 100 receives a face authentication request from the digital asset management device 200 via the network N, and extracts the face feature information from the face image included in the face authentication request as in steps S21 to S23.

[0045] Next, the authentication unit 150 collates the acquired face feature information with the biometric feature information 112 in the biometric information DB 110 (S32). When the face feature information matches, that is, when the degree of match of the face feature information is equal to or greater than a predetermined value (YES in S33), the authentication unit 150 identifies the user ID 111 of the user whose face feature information matches (S34). Then, the authentication unit 150 returns to the digital asset management device 200 a message indicating that the face authentication has succeeded and the identified user ID 111 (S35). When there is no matching face feature information (NO in S33), the authentication unit 150 returns to the digital asset management device 200 a message indicating that the biometric authentication has failed (S36).

[0046] (Digital Asset Management Device 200) Subsequently, the digital asset management device 200 will be described. The digital asset management device 200 is an information processing device that performs information processing for managing a user's digital assets. FIG. 7 is a block diagram showing the configuration of the digital asset management device 200. The digital asset management device 200 includes a storage unit 210, a memory 220, a communication unit 230, and a control unit 240.

[0047] The storage unit 210 is a storage device such as a hard disk or a flash memory. The storage unit 210 stores a program 211 and asset management information 212. The program 211 is a computer program in which the processing of the digital asset management method according to the present embodiment is implemented.

[0048] The asset management information 212 is information for managing a member's digital assets. The asset management information 212 is information that associates member information 2121, agent information 2122, asset information 2123, a set period 2124, and an authority scope 2125. The asset management information 212 is registered, for example, by receiving a member's input via a registration screen 310a described later.

[0049] Hereinafter, in addition to FIG. 7, the asset management information 212 will be described with reference to FIGS. 8 to 10. FIG. 8 is a diagram showing an example of the member information 2121. FIG. 9 is a diagram showing an example of the agent information 2122. FIG. 10 is a diagram showing an example of the asset management information 212.

[0050] The member information 2121 is information regarding a member. The member information 2121 will be described with reference to FIG. 8. The member information 2121 is information that associates, for example, a member ID 2121a that identifies a member and personal information of the member. The member ID 2121a is information corresponding to the user ID 111. The personal information of the member includes information for transmitting a confirmation notice from the digital asset management device 200 to the communication terminal 300. The personal information of the member is, for example, the member's name 2121b, address 2121c, telephone number 2121d, email address 2121e, and face image 2121f. Details of each piece of information will be described later.

[0051] Further, the member information 2121 may include biometric authentication information used for biometric authentication of the member. The biometric authentication information may include a biometric authentication method and biometric feature information. In the present embodiment, the biometric authentication information includes the member's face feature information as biometric feature information. Note that, in the present embodiment, the face feature information is stored as biometric feature information 112 in the biometric information DB 110. The digital asset management device 200 can refer to and manage the member's face feature information stored in the biometric information DB 110 via the member ID 2121a corresponding to the user ID 111 of the authentication device 100. Therefore, it can be said that the member information 2121 substantially includes the member's face feature information.

[0052] The agent information 2122 is information about the agent. The agent information 2122 is registered in association with the member information 2121. For the member information 2121 of one member, a plurality of agent information 2122 of agents may be registered.

[0053] Referring to FIG. 9, the agent information 2122 will be described. The agent information 2122 is information that associates, for example, an agent ID 2122a that identifies an agent with the personal information of the agent. The agent ID 2122a is information corresponding to the user ID 111. The personal information of the agent includes information for transmitting an agent contact from the digital asset management device 200 to the communication terminal 301 or 302. The personal information of the agent is, for example, the name 2122b of the agent, the address 2122c, the phone number 2122d, the email address 2122e, and the face image 2122f. The agent information 2122 may include a relationship 2122g with the member. The relationship 2122g with the member is information indicating, for example, a spouse, child, parent, sibling, or friend.

[0054] Also, similar to the member information 2121, the agent information 2122 may include biometric information used for biometric authentication of the agent. In the present embodiment, the biometric information includes the face feature information of the agent as biometric feature information. The digital asset management device 200 can refer to and manage the face feature information of the agent stored in the biometric information DB 110 via the agent ID 2122a corresponding to the user ID 111 of the authentication device 100. Therefore, it can be said that the agent information 2122 substantially includes the face feature information of the agent.

[0055] Returning to FIG. 7, the description will be continued. The asset information 2123, the set period 2124, and the authority scope 2125 are information associated with the above-described member information 2121 and agent information 2122 for asset management. Referring to FIG. 10, the asset management information 212 will be specifically described. FIG. 10 is a diagram showing an example of the asset management information 212 including the asset information 2123, the set period 2124, and the authority scope 2125.

[0056] The asset information 2123 is information regarding the member's digital assets. The asset information 2123 is information that associates, for example, an asset ID 2123a for identifying an asset with an asset name 2123b indicating the content of the digital asset.

[0057] The set period 2124 is information indicating the period until a confirmation notice is sent to the member. The set period 2124 is associated with the member ID 2121a and the asset ID 2123a. The set period 2124 accepts the member's input and an arbitrary period is set. The set period 2124 may indicate the number of days (for example, 30 days) or months (for example, 2 months) from the date and time of the last access to the digital asset account. Further, the set period 2124 may indicate a specific date and time (for example, XXXX year X month X day XX hour).

[0058] For each digital asset, a different set period 2124 may be set. For example, the member sets the set period 2124 according to the importance of the digital asset. As the importance of the asset increases, by setting the set period 2124 shorter, the period until the digital asset management device 200 sends a confirmation notice becomes shorter. Therefore, when it becomes difficult for the member to respond to the confirmation notice, the agent can quickly grasp the situation. Also, the member may set the set period 2124 according to the access frequency to the account. By setting the set period 2124 shorter for assets with a high access frequency, the same effect can be obtained.

[0059] The authority scope 2125 is information indicating the scope of authority given to the agent. The scope of authority indicates, for example, all or part of the authority regarding the digital asset. The authority scope 2125 is associated with the member ID 2121a, the asset ID 2123a, and the agent ID 2122a. The authority scope 2125 is set within an arbitrary range upon receiving input from the member. The authority scope 2125 may be set for each agent. For example, even for the same asset, different authority scopes 2125 may be set according to the agent. Also, the authority scope 2125 may be set for each asset. For example, even for the same agent, different authority scopes 2125 may be set according to the asset.

[0060] A specific explanation will be given using the example shown in FIG. 10. Let the member with the member ID 2121a being "A1" be member A1, and the agents with the agent IDs 2122a being "B1" and "B2" be agent B1 and agent B2 respectively. Regarding the digital assets of member A1, for the "Internet bank" with the asset ID 2123a being "101", agents B1 and B2 are set. For agent B1, the authority scope 2125 of "All" is set, and for agent B2, the authority scope 2125 of "Notification only" is set. If member A1 does not access the "Internet bank" for a period longer than the set period and does not respond to the confirmation notice, an agent confirmation is sent to agents B1 and B2. If agents B1 and B2 respond and succeed in authentication, agent B1 is given the authority of "All" and B2 is given the authority of "Notification only".

[0061] When the authority scope 2125 is "All" as in the case of agent B1, the digital asset management device 200 gives all the authorities that member A1 has to agent B1. For example, the digital asset management device 200 gives agent B1 all the authorities including the right to use the ID and password for accessing the bank account and the right to manage the account balance. Also, when the authority scope 2125 is "Notification only" as in the case of agent B2, the digital asset management device 200 notifies agent B2 that the digital asset exists. In this case, the digital asset management device 200 notifies agent B2 that member A1 has an Internet bank account, but does not give agent B2 the right to use the ID, password, etc.

[0062] Note that in the above, "all" or "only notifications" are used as an example for the authority scope 2125, but the setting of the authority scope 2125 is not limited to these. For example, the scope of authority may be set for each more detailed item, such as "only login" for "SNS".

[0063] Returning to FIG. 7, the description will continue. The memory 220 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information during the operation of the control unit 240. The communication unit 230 is a communication interface with the network N.

[0064] The control unit 240 is a processor that controls each component of the digital asset management device 200, that is, a control device. The control unit 240 causes the memory 220 to read the program 211 from the storage unit 210 and execute the program 211. Thereby, the control unit 240 realizes the functions of the registration unit 241, the first transmission unit 242, the second transmission unit 243, the authentication control unit 244, and the authorization unit 245.

[0065] The registration unit 241 corresponds to the registration unit 11 in the first embodiment. The registration unit 241 associates the member information 2121 of the member A1 having an account with the agent information 2122 of the agents B1 and B2 and registers it in the asset management information 212. In addition, the registration unit 241 associates these information with the asset information 2123, the set period 2124, and the authority scope 2125 and registers it in the asset management information 212. That is, the registration unit 241 associates a plurality of information used for managing the digital assets of the member A1 and registers the asset management information 212.

[0066] The registration unit 241 can receive an input from the communication terminal 300 via a registration web site or the like and register the asset management information 212. For example, the member A1 inputs necessary items according to the registration screen 310a displayed on the display unit 310. The registration unit 241 receives the input content from the member A1 and registers the asset management information 212.

[0067] FIG. 11 is a diagram showing an example of a registration screen 310a for registering asset management information 212. For example, the registration screen 310a includes a "member information" column for registering member information 2121 and a "registered asset" column for registering agent information 2122, asset information 2123, a set period 2124, and an authority scope 2125.

[0068] The "member information" column includes a member ID 2121a, a name 2121b, an address 2121c, a phone number 2121d, an email address 2121e, and a face image 2121f. Member A1 uses the communication terminal 300 to input necessary items in each column. Note that the member ID 2121a may be automatically numbered.

[0069] The email address 2121e is, for example, an email address capable of receiving confirmation notifications transmitted from the digital asset management device 200 on the communication terminal 300. Also, a plurality of email addresses 2121e may be registered. Not limited to this, for example, when confirmation notifications are made by notifications of a predetermined application or when confirmation notifications are made by automatic voice to the phone number 2121d, the email address 2121e may not be required.

[0070] The face image 2121f may be taken using a camera connected to the communication terminal 300 or a camera built into the communication terminal 300, or a pre-taken image file may be registered. When member A1 uses face authentication, the authentication device 100 may extract face feature information from the face image 2121f and register the face feature information in the biometric information DB 110.

[0071] The "registered asset" column includes an asset ID 2123a, an asset name 2123b, a set period 2124, the name 2122b of the agent, a relationship 2122g, and an authority scope 2125. Similar to the "member information" column, member A1 inputs necessary items in the "registered asset" column. Note that the asset ID 2123a may be automatically numbered. As described above, member A1 can set the agent information 2122, the set period 2124, and the authority scope 2125 for each asset with different contents.

[0072] Regarding the agent information 2122, since it can be input by using a display screen similar to the "member information" column on the registration screen 310a, the illustration and detailed description are omitted. Member A1 may input the name 2122b, address 2122c, phone number 2122d, email address 2122e, face image 2122f, and relationship 2122g of the agent in the same manner as the member information 2121. Note that the agent B1 or B2 may input the agent information 2122.

[0073] Regarding the registration of an agent, an approval confirmation may be performed to confirm with the agent whether to approve the registration as an agent. For example, the registration unit 241 sends an approval confirmation email to the email addresses 2122e of the agents B1 and B2, and registers the agent information 2122 of the agents B1 and B2 when a reply indicating approval is received.

[0074] Note that the content of the registration screen 310a is not limited to that shown in FIG. 11. For example, the "member information" column and the "registered assets" column may not be displayed on the same screen. Also, only a part of the display content shown in FIG. 11 may be displayed, or other elements may be further displayed.

[0075] FIG. 12 is a diagram showing an example of another registration screen 310b for registering the asset management information 212. For example, the registration screen 310b includes input fields for the asset name 2123b, setting period 2124, agent name 2122b, relationship 2122g, and authority scope 2125.

[0076] Each input field may be configured to allow input not only by direct input but also in the form of a pull-down menu or radio buttons. Members can easily input by selecting the desired input content from multiple input candidates. As an example, in the same figure, a setting period selection area 2124a for inputting the setting period 2124 in the form of radio buttons is shown. The setting period selection area 2124a displays options of "30 days", "2 months", and "6 months" and accepts any selection from the member. The setting period selection area 2124a may also accept input of the setting period 2124 by calendar display.

[0077] The setting period selection area 2124a may display different input candidates according to the digital asset, member, or agent. For example, as the value of the digital asset increases, the setting period selection area 2124a displays shorter periods as candidates. As a result, the higher the asset value, the easier it is to set a shorter setting period 2124. The value of the digital asset may be determined based on the amount, or may be determined based on the importance of the digital asset set by the member.

[0078] Also, on the registration screen 310b, when inputting the agent's name 2122b, the biometric information of the agent or a certificate proving that the person is an agent may be registered. Also, the biometric information of the agent may be notified to the agent to that effect when the principal sets the agent, and registered on the communication terminal of the agent. At this time, the agent may be asked for consent to act as an agent.

[0079] (Registration process of asset management information) The registration process of the asset management information 212 performed by the digital asset management device 200 will be described using a flowchart. The registration process of the asset management information 212 is a process of registering by associating member information 2121, agent information 2122, asset information 2123, setting period 2124, and scope of authority 2125. The digital asset management device 200 accepts the input of member A1 on the communication terminal 300 and registers the asset management information 212.

[0080] Figure 13 is a flowchart showing the registration process of the asset management information 212. First, the registration unit 241 registers the member information 2121 (S41). The member information 2121 may include a face image 2121f used for biometric authentication of member A1, etc. Next, the registration unit 241 registers the asset information 2123 in association with the member information 2121 (S42). Subsequently, the registration unit 241 registers the set period 2124 until confirmation contact is sent for each asset (S43). The set period 2124 may be set to different periods depending on the digital asset. Then, the registration unit 241 registers the agent information 2122 for each asset (S44). The agent information 2122 may include a face image 2122f used for biometric authentication of the agent, etc. Also, for the member information 2121 of one member, the agent information 2122 of multiple agents may be registered. Finally, the registration unit 241 registers the scope of authority given to the agent for each agent (S45). Depending on the agent, the scope of authority given may be different. Also, even for the same agent, the scope of authority given may be different depending on the asset.

[0081] Note that the order of processing is not limited to the order described above. It may be processed in a different order as appropriate. Also, when there are multiple agents or assets, the processing in steps S42 to S45 is repeated as appropriate.

[0082] Returning to FIG. 7, the description of the control unit 240 continues. The first transmission unit 242 corresponds to the first transmission unit 12 of Embodiment 1. The first transmission unit 242 sends a confirmation notice to the member when there has been no access to the account for a set period or longer set by the member.

[0083] For example, in the example shown in FIG. 10, member A1 has set the set period 2124 to "30 days" for the "Internet bank" with asset ID "101". Therefore, the first transmission unit 242 sends a confirmation notice to member A1 when there has been no access from member A1 to the account of this Internet bank for 30 days or longer.

[0084] The first transmission unit 242 determines whether there has been an access from member A1 to the account, for example, based on whether there is a login to the web service of the online bank. For example, the first transmission unit 242 obtains the last login date and time to the web service and measures the elapsed period. If 30 days or more have elapsed without a login, the first transmission unit 242 determines that there has been no access from member A1 to the account for the set period or more. If there is a login again within 30 days, the first transmission unit 242 resets the elapsed period and measures the elapsed period again from the last login date and time. Not limited to this, the first transmission unit 242 may determine that there has been an access by member A1 based on an application such as a smartphone corresponding to the web service, or by using the balance of the online bank account or checking the balance at an ATM or the like. The determination of whether there is an access to the account is not limited to the above. The first transmission unit 242 may determine whether there is an access to the account according to the digital assets.

[0085] When the first transmission unit 242 determines that there has been no access for the set period or more, it refers to the member information 2121 and obtains the email address 2121e of member A1 (see FIG. 8). The first transmission unit 242 sends an email for confirmation contact to the obtained email address. The confirmation contact is a contact for checking the status of member A1. The confirmation contact may be an email including a message such as "Dear Mr. Member A1, you have not accessed the account of ○○ Bank for 30 days or more. Please reply to this email for confirmation." The confirmation contact may simply require a reply or may include items for selecting the status of member A1. The status of member A1 may indicate contents such as "busy" or "not feeling well". Also, the confirmation contact may include a response deadline.

[0086] Note that the confirmation and notification are not limited to email and can be in any form. For example, the first transmission unit 242 may obtain the phone number 2121d and use SMS (Short Message Service) to send a confirmation and notification, or may perform a confirmation and notification by means of an automated voice or the like. Further, the first transmission unit 242 may perform a confirmation and notification by means of a push notification or the like via a predetermined application installed in the communication terminal 300.

[0087] In the present embodiment, the digital asset management device 200 uses email to perform confirmation and agent notifications. In the following description, sending a confirmation email to the email address 2121e of member A1 may be simply indicated as "sending a confirmation to member A1". Similarly, sending an agent notification email to the email addresses 2122e of agents B1 and B2 may be simply indicated as "sending an agent notification to agents B1 and B2". The same applies to contacts or notifications other than confirmation and agent notifications.

[0088] The first transmission unit 242 may notify agents B1 and B2 that a confirmation has been sent to member A1. Thereby, agents B1 and B2 can grasp that member A1 has not accessed the account for a period longer than the set period. The first transmission unit 242 refers to the agent information 2122 to obtain the email addresses 2122e of agents B1 and B2 and sends an email indicating that a confirmation has been made. The email may include a message such as "Member A1 has not accessed the account of ○○ Bank for more than 30 days. A confirmation email has been sent to member A1."

[0089] The second transmission unit 243 corresponds to the second transmission unit 13 of Embodiment 1. When there is no member response from member A1 to the confirmation notice sent from the first transmission unit 242 to the email address of member A1, the second transmission unit 243 sends an agent notice to agents B1 and B2. The member response indicates the response of member A1 to the confirmation notice. For example, when the second transmission unit 243 receives a reply email from member A1 to the confirmation notice, it determines that there is a member response. The agent notice notifies the agent that there is no response from member A1. The agent notice may be an email containing a message such as "There is no response from member A1. Please reply to this email."

[0090] If there is no member response within a predetermined period (e.g., one day) after the confirmation email is sent, the second transmission unit 243 sends the above-mentioned agent notice. Similar to the set period 2124, the predetermined period may accept input from member A1 and be set for each asset and agent, or an arbitrary period may be automatically set. The second transmission unit 243 refers to the agent information 2122 to obtain the email addresses 2122e of agents B1 and B2, and sends the agent notice to agents B1 and B2.

[0091] Note that the second transmission unit 243 may notify member A1 that it will send an agent notice before sending the agent notice. For example, the second transmission unit 243 sends a message such as "We will notify agents B1 and B2 that there is no response from member A1." to the email address of member A1. This can prevent the agent notice from being sent to agents B1 and B2 when member A1 simply forgets to make a member response.

[0092] In addition, the second transmission unit 243 may notify member A1 that there has been an agent response from agent B1 or B2 in response to the agent contact. The agent response indicates the response of agent B1 or B2 to the agent contact. For example, when the second transmission unit 243 receives a reply email from agent B1 or B2 in response to the agent contact, it determines that there has been an agent response. The second transmission unit 243 transmits an email containing a message such as "There has been a response from Mr. Agent B1" to the email address of member A1. This enables member A1 to be aware that there has been a response from agent B1 or B2 even if member A1 did not notice the notification of sending the confirmation contact and the agent contact.

[0093] In addition, when there is a member response from member A1 in response to the confirmation contact to member A1, the second transmission unit 243 may notify agents B1 and B2 that there has been a member response from member A1. The second transmission unit 243 transmits a message such as "There has been a response from Mr. Member A1" to the email addresses of agents B1 and B2. This enables agents B1 and B2 to confirm that member A1 is in a state where they can respond. Also, since the timing of the confirmation contact and the timing of the confirmation response can be grasped, agents B1 and B2 can grasp the time from when member A1 receives the confirmation contact until they send the confirmation response. This enables them to grasp whether member A1 is responding promptly or taking a long time to respond.

[0094] Note that the first transmission unit 242 and the second transmission unit 243 can confirm the status of the agents by sending an agent confirmation contact to agents B1 and B2 in the same way as the status confirmation of member A1 described above. The agent confirmation contact is for confirming the status of agents B1 and B2. The agent confirmation contact may be sent at any timing. By sending the agent confirmation contact regularly (for example, every three months), the status of the agents can be confirmed.

[0095] Specifically, first, the first transmission unit 242 transmits an agent confirmation notice to the agent. The agent confirmation notice may be, for example, an email containing a message such as "Dear Agent B1, please reply to this email for status confirmation." The second transmission unit 243 notifies the member A1 that there is no response to the agent confirmation notice when there is no response from Agent B1 or B2 to the agent confirmation notice. The notice to the member A1 may be, for example, an email containing a message such as "An agent confirmation notice has been sent to Agent B1, but there has been no response." As a result, the member A1 can grasp the status of Agents B1 and B2, and thus can consider adding or changing agents according to the situation.

[0096] The authentication control unit 244 corresponds to the authentication control unit 14 in Embodiment 1. When there is an agent response from the agent to the agent notice, the authentication control unit 244 controls the authentication of the agent. The authentication control unit 244 controls the authentication to perform the identity authentication of the agent using biometric authentication, two-factor authentication, etc. In this embodiment, the authentication control unit 244 controls the face authentication of the agent. As already explained, the agent information 2122 includes the face feature information of the agent used for the face authentication of the agent. Also, the digital asset management device 200 can refer to and manage the face feature information of the agent stored in the biometric information DB110 via the agent ID 2122a corresponding to the user ID 111.

[0097] The authentication control unit 244 receives a face authentication request including the face image of Agent B1 or B2 via the communication terminal 301 or 302. The authentication control unit 244 transmits the face authentication request including the face image of Agent B1 or B2 to the authentication device 100. The authentication control unit 244 receives the result of the face authentication from the authentication device 100.

[0098] The authorization unit 245 corresponds to the authorization unit 15 in Embodiment 1. When the authentication of Agent B1 or B2 is successful, the authorization unit 245 refers to the asset management information 212 and grants the agent B1 or B2 the authority regarding the digital assets of the member A1.

[0099] In the example of FIG. 10 described above, member A1 sets the authority scope of "all" for the agent B1 who is the spouse, and sets the authority scope of "notification only" for the agent B2 who is the child. Therefore, when the agent B1 successfully authenticates, the authority granting unit 245 grants all authorities regarding the digital asset "Internet banking" to the agent B1. The authority granting unit 245 performs, for example, notification of the existence of an account, disclosure of an ID and a password, disclosure of the content of a digital asset, and guidance on account transfer procedures or continued use to the agent B1. For example, the authority granting unit 245 transmits information regarding these to the email address of the agent B1. Thereby, the agent B1 can access the digital asset "Internet banking" of the member A1 using the disclosed ID and password. The agent B1 can manage the digital assets of the member A1 on behalf of the member A1.

[0100] Also, when the agent B2 successfully authenticates, the authority granting unit 245 grants the authority to receive notification of the existence of an account to the agent B2. For example, the authority granting unit 245 transmits information for notifying the existence of an account to the email address of the agent B2. Thereby, the agent B2 can grasp the existence of the digital asset "Internet banking" of the member A1.

[0101] (Digital Asset Management Process) Subsequently, the process performed by the digital asset management apparatus 200 will be described using the flowcharts shown in FIGS. 14 to 16. FIG. 14 is a flowchart showing a confirmation contact transmission process for transmitting a confirmation contact to the member A1. FIG. 15 is a flowchart showing an agent contact transmission process for transmitting an agent contact to the agents B1 and B2. FIG. 16 is a flowchart showing an authentication control process and an authority granting process for the agents B1 and B2. Note that hereinafter, reference will be made to FIGS. 7 to 10 for the description.

[0102] First, the confirmation contact transmission process will be described with reference to FIG. 14. The first transmission unit 242 refers to the asset management information 212 and acquires the set period 2124 set by member A1 associated with the digital asset. The first transmission unit 242 determines whether there has been access by member A1 to the account for a period equal to or longer than the set period (S51). If there has been access (YES in S51), the process of step S51 is repeated. If there has been no access (NO in S51), the first transmission unit 242 refers to the asset management information 212 and acquires the email address 2121e of member A1. The first transmission unit 242 transmits a confirmation contact to the acquired email address of member A1 (S52). The first transmission unit 242 acquires the email addresses 2122e of agents B1 and B2 and transmits a notice that the confirmation contact has been sent to each of their email addresses (S53). Note that in the following processes as well, each functional unit of the digital asset management device 200 refers to the asset management information 212 to acquire the email addresses of member A1, etc. Redundant explanations will be omitted below.

[0103] Subsequently, the agent contact transmission process will be described with reference to FIG. 15. The second transmission unit 243 determines whether there has been a member response from member A1 within a predetermined period (S61). If there has been a member response from member A1 (YES in S61), the second transmission unit 243 notifies agents B1 and B2 that there has been a member response from member A1 (S64) and ends the process.

[0104] If there has been no member response from member A1 (NO in S61), the second transmission unit 243 notifies member A1 that an agent contact will be transmitted (S62). The second transmission unit 243 transmits an agent contact to agent B1 or B2 (S63). Note that if there has been a response from member A1 before transmitting the agent contact, the process ends without transmitting the agent contact.

[0105] Subsequently, the authentication control process and the authorization process will be described with reference to FIG. 16. The second transmission unit 243 determines whether an agent response has been received from agent B1 or B2 (S71). If no agent response has been received from either agent B1 or B2 (NO in S71), the second transmission unit 243 notifies member A1 to that effect (S77) and ends the process.

[0106] If an agent response has been received from agent B1 or B2 (YES in S71), the second transmission unit 243 notifies member A1 to that effect (S72). Here, it is assumed that agent responses have been received from both agent B1 and B2. The authentication control unit 244 receives an authentication request from agent B1 or B2 via the communication terminal 301 or 302 and controls the authentication of agent B1 or B2 (S73). Here, the authentication control unit 244 receives a face authentication request including the face image of agent B1 or B2 and transmits the face authentication request to the authentication device 100. The authentication control unit 244 receives the result of the face authentication from the authentication device 100.

[0107] The authority granting unit 245 determines whether the authentication of agent B1 or B2 has been successful (S74). If the authentication fails (NO in S74), the authority granting unit 245 does not grant the authority to agent B1 or B2, notifies of the authentication failure (S78), and ends the process. If the authentication is successful (YES in S74), the authority granting unit 245 grants the authority regarding the digital assets of member A1 to agent B1 or B2 (S75). Here, it is assumed that both agent B1 and B2 have succeeded in face authentication. The authority granting unit 245 refers to the asset management information 212 and grants the authority to agent B1 and B2 according to the set authority range 2125. For example, the authority granting unit 245 grants all the authorities to agent B1 and part of the authorities to agent B2. The authority granting unit 245 notifies member A1, agent B1, and agent B2 that the authority to the digital assets has been granted to agent B1 and B2 (S76) and ends the process.

[0108] Note that the digital asset management device 200 may perform an agent confirmation process for checking the status of the agent at any timing. FIG. 17 is a flowchart showing the agent confirmation process. The first transmission unit 242 transmits an agent confirmation notice to agents B1 and B2 (S81). The second transmission unit 243 determines whether there is a response from agent B1 or B2 to the agent confirmation notice (S82). If there is a response (YES in S82), the process ends. If there is no response (NO in S82), the second transmission unit 243 notifies member A1 that there is no response to the agent confirmation notice (S83). Note that the second transmission unit 243 may notify member A1 to that effect when there is a response from agent B1 or B2 in step S82 (YES in S82).

[0109] As described above, in the digital asset management system 1000 according to this embodiment, in the digital asset management device 200, the registration unit 241 registers the agent information of the agent with respect to the member information of the member having the account. The first transmission unit 242 transmits a confirmation notice to the member when there is no access to the account for a set period or longer set by the member. The second transmission unit 243 transmits an agent notice to the agent when there is no member response from the member to the confirmation notice. The authentication control unit 244 controls the authentication of the agent when there is an agent response from the agent to the agent notice. The authorization unit 245 grants the agent the authority regarding the digital assets of the member when the authentication of the agent is successful.

[0110] By doing so, even when it becomes difficult for the member to manage the digital assets, it is possible to prevent the digital assets from being left unattended without a manager. Also, in the digital asset management device 200, the set period until the confirmation notice is transmitted can be set to different periods according to the digital assets. Thereby, it is possible to send a confirmation notice to the member at an appropriate period according to the access frequency and the importance of the assets.

[0111] In the digital asset management device 200, since multiple agents can be set for a single member, different permissions can be set according to the agents. Thus, asset transfer can be performed according to the relationship between the member and the agent. For example, the scope of permissions can be set to gradually decrease in the order of spouse, child, and friend.

[0112] Furthermore, in the digital asset management device 200, since the fact that a confirmation notice has been sent to the member and the fact that there has been a member response from the member are notified to the agent, even when the member is in a situation where they can respond, the agent can be appropriately contacted. By doing so, the agent can grasp the situation of the member not only when the member becomes unable to respond, but also in advance. Therefore, for example, changes such as a delay in the member's response can be quickly grasped. This makes it easier to perform asset transfer that reflects the member's intention between the member and the agent.

[0113] Also, in the digital asset management device 200, by sending an agent confirmation notice to the agent, the member can grasp whether the agent is in a situation where they can respond. Thus, even when it becomes difficult to transfer assets to the agent, the member can respond promptly. Also, in the digital asset management system 1000, biometric authentication can be performed in the authentication device 100, so strict authentication of the agent can be performed before granting authority to the agent.

[0114] Note that the configuration of the digital asset management system 1000 shown using FIG. 3 is merely an example. Each of the authentication device 100, the digital asset management device 200, the communication terminal 300, the communication terminal 301, and the communication terminal 302 may be configured using a device that integrates a plurality of components, or the respective functional units may be distributed and processed using a plurality of devices. For example, the functions of the authentication device 100 and the digital asset management device 200 may be integrated into the same device.

[0115] <Example of Hardware Configuration> Each functional component of the authentication device 100, the digital asset management device 200, the communication terminal 300, the communication terminal 301, and the communication terminal 302 may be implemented by hardware (e.g., hard-wired electronic circuits, etc.) that implements each functional component, or may be implemented by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls it, etc.). Hereinafter, the case where each functional component of the authentication device 100, etc. is implemented by a combination of hardware and software will be further described.
