The identity management system according to claim 9, wherein the feature word processing unit processes a result of the scoring of the feature words such that the result of the scoring is shown in a predetermined mode in the feature-word relationship display information.
The identity management system according to any one of claims 7 to 10, wherein the feature word processing unit generates, for each identity, a plurality of pieces of feature-word relationship information corresponding to characteristics of the respective identities which are different from each other.
The identity management system according to any one of claims 7 to 11, wherein the feature word processing unit generates integrated feature-word relationship information which is made by integrating a plurality of pieces of feature-word relationship information.
The identity management system according to claim 12, wherein the feature word processing unit reconstructs an integrated feature-word relationship information from a plurality of pieces of feature-word relationship information which is partly selected from the plurality of pieces of feature-word relationship information which are used to generate the integrated feature-word relationship information.
The identity management system according to any one of claims 7 to 13, further comprising a matching unit which determines matching of the plurality of identities, based on a similarity condition provided by the feature-word relationship information assigned to every plurality of identities that have been matched.
The identity management system according to claim 14, wherein the feature word processing unit generates the integrated feature-word relationship information which is provided by integrating the feature-word relationship information, for every identity matched by the matching unit.
An identity management method performed in an identity management system, wherein a feature word processing unit comprises a feature word processing step, wherein the feature word processing unit performs, for each identity, extraction of feature words and determination of a relationship between the feature words and generates feature-word relationship information indicating the determined relationship, based on a content of an identity-specific information stored in a memory unit, the identity-specific information corresponding and being specific to the identities which correspond to both an identity serving as a real user who exists in a physical space and an identity serving as an avatar which is allowed to exist in a metaverse.
A program enabling a computer installed in an identity management system as a feature word processing unit, wherein the feature word processing unit performs, for each identity, extraction of feature words and determination of a relationship between the feature words and generates feature-word relationship information indicating the determined relationship, based on a content of an identity-specific information stored in a memory unit, the identity-specific information corresponding and being specific to the identities which correspond to both an identity serving as a real user who exists in a physical space and an identity serving as an avatar which is allowed to exist in a metaverse.

Description

[Technical Field] The present invention relates to an identity management system, an identity management method, and program. The present application is based on and claims the benefits of priorities from Japanese Patent Application Nos. 2023-107259 and 2023-135662 respectively filed in Japan on June 29, 2023 and Aug. 23, 2023, the contents of which are incorporated herein by reference. [Background Art] There is known technology in which avatars in a digital space can perform actions such as purchasing digital objects in response to user operations (see, for example, PTL 1). [Citation List] [Patent Literature] [PTL 1] JP 2022-117111 A [Summary of the Invention] [Problem to be Solved by the Invention] When real users act in the physical space or when avatars representing those real users or other users act in the digital space, various types of authentication (i.e., proof of identity, proof of meeting certain requirements, proof of authority, etc.) are required in various situations, and the type of such required authentication may vary. Considering such situations, it is desirable to efficiently manage qualifications related to the existence (identity) of real users, avatars, etc. Each real user existing in the physical space has a different personality. In addition, avatars existing in digital spaces (metaverse) that correspond to real users will also differ in personality depending on the personality of the corresponding real users and their previous actions in the digital space. With consideration of such differences, if information about the characteristics of identities such as real users and avatars can be effectively utilized in the identity activity space, it will be desirable to improve interest and convenience. The purpose of the present invention is to enable efficient management of qualifications related to identities and to enable effective utilization of the characteristics of identities in the identity activity space. [Solution to Problem] A first mode of the present invention which is to realize the foregoing object relates to an identity management system, including a qualification management unit that stores a predetermined plurality of pieces of qualification information into a memory unit such that the predetermined plurality of pieces of qualification information are made to correspond to a single information storage medium owned by a real user existing in a physical space, the predetermined plurality of pieces of qualification information being among: one or more pieces of qualification information being assigned to an identity serving as the real user, the user having a predetermined qualification; and one or more pieces of qualification information being assigned to an identity serving as an avatar which is allowed to exist in a metaverse and corresponds to the real user. A second mode of the present invention relates to the identity management system according to the first mode, wherein the qualification information includes identification information that proves a status of the identity. A third mode of the present invention relates to the identity management system according to the first mode or the second mode, wherein the qualification information includes authenticity proof information that proves authenticity of the identity. A fourth mode of the present invention relates to the identity management system according to any one of the first to third modes, wherein the qualification management unit outputs qualification information serving as information for confirming an identity to be confirmed, the qualification information being selected from the qualification information stored in the memory unit, based on an operation performed by the real user on a corresponding user terminal. A fifth mode of the present invention relates to an identity management method, the method comprising: a qualification management step, wherein a qualification management unit stores a predetermined plurality of pieces of qualification information into a memory unit such that the predetermined plurality of pieces of qualification information are made to correspond to a single information storage medium owned by a real user existing in a physical space, the predetermined plurality of pieces of qualification information being among: one or more pieces of qualification information being assigned to an identity serving as the real user, the user having a predetermined qualification; and one or more pieces of qualification information being assigned to an identity serving as an avatar which is allowed to exist in a metaverse and corresponds to the real user. A sixth mode of the present invention relates to a program performed by a computer installed in an identity management system, wherein the computer is worked as a qualification management unit that stores a predetermined plurality of pieces of qualification information into a memory unit such that the predetermined plurality of pieces of qualification
