Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of and claims the benefit of priority to International Application No. PCT/JP2024/023581, filed Jun. 28, 2024, which is based upon and claims the benefit of priority to Japanese Patent Application Nos. 2023-107259 and 2023-135662 respectively filed in Japan on Jun. 29, 2023 and Aug. 23, 2023, the entire contents of each of which are incorporated herein by reference. BACKGROUND OF THE INVENTION There are known technologies in which avatars in a digital space can perform actions such as purchasing digital objects in response to user operations. See, for example JP 2022-117111 A. The entire contents of this publication are incorporated herein by reference. SUMMARY OF 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. A first mode of the present invention 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 plura
