Description

[Technical field]

[0001] The present invention relates to an inheritance system in a virtual space using blockchain technology. [Background technology]

[0002] In recent years, the virtual space (metaverse) has developed rapidly, and users can now freely act within it and acquire and use various digital assets. Blockchain technology is often used to distribute these digital assets. In addition, users act as avatars within the virtual space, and the management of digital assets is also linked to user information.

[0003] Incidentally, it is rare for user information to disappear in a virtual space, such as when an avatar disappears. However, in current Internet services, a user can set an expiration date for an account registered by the user, and when the expiration date arrives, the account is automatically invalidated. In addition, there are systems in which an expiration date is set as a pre-defined rule, even if the user does not set an expiration date. For example, the self-destructing data distribution system described in Patent Document 1 has a function of destructing itself or the entire system including itself. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2002-196984 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, such a system has a problem in that it is unclear what to do with the digital assets owned by a user when the account is invalidated. In other words, when a user's account is deleted, the digital assets owned by the user are not properly managed or moved, and the assets may be lost or left abandoned.

[0006] Therefore, the present invention provides a rule (inheritance rule) for appropriately transferring digital assets owned by a user when the user's account is terminated, preventing the loss or abandonment of assets. This makes it possible to make the distribution and management of digital assets in virtual space safer and more reliable.

[0007] (1) The virtual space inheritance system of the present invention is characterized in that, in a virtual space in which user information registered by a user is set to be erased, a memory unit stores asset information contained in the user information and inheritance regulation information to which the asset information is moved when the user information is erased, and the asset information is moved in accordance with the inheritance regulation information due to the erasure of the user information.

[0008] In this virtual space inheritance system, when user information disappears within the virtual space, it is possible to properly transfer asset information, including digital assets owned by the user. This makes it possible to prevent digital assets from being lost or left abandoned due to the disappearance of an account. In addition, this virtual space inheritance system makes it possible to transfer digital assets transparently and traceably by utilizing blockchain technology. This ensures the reliability of the transfer of asset information, including digital assets, and maintains the safety and reliability of the assets even after the transfer.

[0009] (2) A virtual space inheritance system according to claim 1, wherein, when the asset information is transferred, a portion of the asset value is collected at a predetermined interest rate for a portion of the asset information.

[0010] In this virtual inheritance system, when asset information is transferred, a portion of the asset value is collected at a set interest rate, which makes it possible to cover the costs required for maintaining and operating the system.

[0011] (3) In the virtual space inheritance system, the inheritance provision information is registered by the user, including the recipient of the transfer and the asset value to be transferred.

[0012] In this virtual space inheritance system, users can set the inheritance rules themselves, so it is possible to directly reflect the user's wishes. This allows users to freely register who their assets will be transferred to and how much value they will be transferred to when they die. Effect of the Invention

[0013] This virtual space inheritance system can prevent the loss or abandonment of digital assets due to the deletion of accounts, guarantee the reliability of the transfer of asset information, including digital assets, and maintain the safety and reliability of the assets even after the transfer.

[Diagram 2] FIG. 1 is a functional block diagram of a virtual space inheritance system according to an embodiment of the present invention. [Diagram 3] FIG. 2 is a flow diagram of the operation of the virtual space inheritance system according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A virtual space inheritance system S according to an embodiment of the present invention will be described with reference to the drawings.

[0016] As shown in Fig. 1, the virtual space inheritance system S is connected to multiple blockchains via a network (not shown) such as the Internet. In this embodiment, the virtual space inheritance system S cooperates with a real estate management blockchain B2B1, a real estate management blockchain, a securities management blockchain B3, an insurance contract management blockchain B4, and an intellectual property blockchain B5.

[0017] The virtual space inheritance system S is operated by an information processing device such as a well-known server, and is composed of functional blocks that execute the transfer of assets within the virtual space according to predetermined conditions.

[0018] The virtual space inheritance system S comprises a virtual space generation unit 21, a user information registration unit 22, an asset information management unit 23, a user information disappearance monitoring unit 24, a mobile asset collection unit 25, a blockchain collaboration unit 2626, a memory unit 27, and a control unit 28.

[0019] As is well known in the art, the virtual space generating unit 21 generates a virtual space that a user can experience. The user's actions, interactions, transactions, etc. are carried out in this virtual space.

[0020] The user information registration unit 22 allows a user to register user information such as his / her own asset information, inheritance regulation information, and extinction conditions using a unique avatar or digital ID in the virtual space. The user information is recorded in the corresponding blockchain by the blockchain linking unit 26, and can be tamper-proofed and transparent.

[0021] In addition to basic personal information such as the user's name, age, gender, address, email address, and telephone number, user information includes avatar information for identifying the user in the virtual space, asset information such as digital currency, tokenized physical assets, securities, insurance policies, and intellectual property held by the user, inheritance policy information that determines how assets will be inherited when a user meets certain extinction conditions, and information on the conditions (extinction conditions) under which a user will cease activities in the virtual space and as a result asset inheritance will occur.

[0022] In particular, the inheritance provision information includes details such as information on the destination (heirs) of the assets to be transferred, and the proportion and type of assets that each heir should receive. The extinction clause includes information set by the user in addition to information set in advance by the virtual space inheritance system S. The inheritance provision information includes cases where the user does not log in for a certain period of time, or where health data or activity data is not reported for a certain period of time, or where a certain period of time has passed since user registration, etc.

[0023] The asset information management unit 23 manages asset information for each user. The asset information includes information such as digital currency, tokenized physical assets, securities, insurance contracts, and intellectual property. Note that tokenized physical assets include real estate, artworks, and precious metals. When the user information is lost, a transaction for transferring assets is executed on each blockchain linked to the virtual space inheritance system S in accordance with the inheritance provision information described later.

[0024] The user information disappearance monitoring unit 24 monitors the user's activity status and leaves a record on each linked blockchain when the set disappearance condition is met. This record is triggered by the disappearance of the user information and instructs the asset information management unit 23 to transfer assets.

[0025] The transferred asset collection unit 25 executes a smart contract to collect a portion of the asset value of the transferred assets when a change in asset information (transfer of assets) occurs triggered by the disappearance of user information on each blockchain linked by the virtual space inheritance system S at the time of transfer of assets.

[0026] The blockchain linking unit 26 links the virtual space inheritance system S with each blockchain. As a result, the blockchain linking unit 26 can execute the functions of each unit, such as registering user information, managing asset information, monitoring the disappearance of user information, and collecting asset value, by linking them with the blockchain.

[0027] The storage unit 27 stores asset information and inheritance regulation information for each user. It also stores and stores system setting information such as the conditions for the disappearance of user information and the interest rate on the asset value collected by the virtual space inheritance system S. All information is also recorded on the blockchain to prevent tampering and maintain transparency.

[0028] The control unit 28 controls each part of the functional block of the virtual space inheritance system S. In particular, when the disappearance of user information is detected, it issues an instruction to transfer asset information according to the inheritance regulation information. It also issues an instruction to collect a part of the asset value accompanying the transfer of assets, and reflects the result in each blockchain and the linking unit.

[0029] Next, the operation of the virtual space inheritance system S will be described.

[0030] First, in order to log in to the virtual space generated by the virtual space generation unit 21, the user information of the user who will log in is registered by the user information registration unit 22. (User registration step T1) After registering the user information, the user performs activities such as actions, interactions, and transactions including the transfer of assets in the virtual space. The asset information management unit 23 manages the user's assets.

[0031] Next, the user information disappearance monitoring unit 24 monitors the user's activity status. When the user's activity meets the set disappearance condition, it is determined that the user's information has disappeared. (User information disappearance process T2) The disappearance condition includes, for example, an disappearance condition set in advance in the virtual space inheritance system S, such as an inability to confirm activity in the virtual space for a certain period of time, as well as an disappearance condition registered by the user when registering the user.

[0032] Next, when the user information disappearance monitoring unit 24 determines that user information has disappeared, the asset information management unit 23, in response to instructions from the user's asset information control unit 28, executes a transaction on each blockchain to transfer the user's assets based on the inheritance regulation information (asset transfer process T3).

[0033] Next, when the transfer asset collecting unit 25 executes a transaction to transfer assets based on the inheritance provision information, the system executes a smart contract to collect a part of the assets to be transferred (transfer asset collecting step T4). The smart contract is specified in advance by the virtual space inheritance system S.

[0034] The asset information management unit 23 and the transfer asset collection unit 25 cooperate with the blockchain cooperation unit 26 to exchange information between the virtual space inheritance system S and various blockchains. The blockchain cooperation unit 26 cooperates with each unit so that the functions of each unit, such as registering user information, managing asset information, monitoring the disappearance of user information, and collecting asset value, are accurately executed on the blockchain.

[0035] In addition, the storage unit 27 stores each user's asset information, inheritance regulation information, system setting information, etc., and provides them to each unit as necessary. This information is also recorded on the blockchain to prevent tampering and maintain transparency.

[0036] As described above, the virtual space inheritance system S operates with each part working together, and inheritance is carried out automatically when a user disappears (dies).

[0037] The above detailed description is intended to provide a specific embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications can be made within the scope of the present invention based on the suggestions of the embodiments. Such changes and modifications are also included within the scope of the present invention. [Industrial Applicability]

[0038] The present invention can be used for the transfer of asset information, such as inheritance, in a virtual space. [Explanation of symbols]
