A DID-based Avatar Bill of Materials Verification Methodfor SW Package Management of Digital Human Components

The 3D avatar used in the metaverse environment is used as a main medium for expressing the user's personality within the virtual space. These avatars are not just appearance data, but are composed of various components, so systematic management is needed to prevent them from being used for cybercrime such as impersonation and theft. However, security issues are emerging as cybercrime cases increase in a metaverse environment that centrally manages user personal information and avatar-related information. Accordingly, this paper proposes a way for avatar owners to safely manage personal information and avatar information using distributed identity verification technology and verify it in a reliable way in a metaverse environment. The avatar specification used in the proposed technique provides 3D avatar file information in the form of a bill of materials (BoM) to verify the commercial use of avatars and whether they can be redistributed or modified without permission, and the service provider, the metaverse platform, can verify the identity consistency of the avatar owner.
