초록
디지털휴먼은 디지털 신원 인증 대상인 사용자의 개성과 신원을 메타버스 내에서 시각화하여 사용자 간의상호작용을 통해 경제활동 및 사회참여를 구현한다. 이 같은 디지털휴먼은 사칭 및 도용 문제를 방지하기 위해 사용자에 대한 신원 인증 과정이 필수적이다. 하지만 대부분의 메타버스 플랫폼은 중앙 서버 의존에서 비롯된 보안 취약점이 존재하거나, 분산화된 블록체인 환경에서 신원과 관련된 정보가 공개될 수 있다는 잠재적인 문제가 발생한다. 따라서 본 논문에서는 메타버스환경에서 디지털휴먼의 신원 인증 및 소유권 증명 문제를 해결하기 위해SBT와 NFT를 활용한 통합 인증 시스템을 제안한다. 제안 시스템에서 사용자는 KYC인증을 통해 플랫폼으로부터 SBT를 발급받으며, 디지털휴먼에 대한 신원 인증은 스마트컨트랙트를 통해 이루어진다. 이는 한 번의스마트컨트랙트를 통해 소유권과 신원 인증을 처리함으로써 인증 과정의 효율성을 높인다. 제안 시스템을 통해 안전하고 효율적인 디지털 신원 관리 시스템의 구축할 수 있을 것으로 기대한다.
Abstract
Digital Human visualizes the personality and identity of users subject to digital identity authentication within the metaverse and realizes economic activities and social participation through interaction between users. For these digital humans, an identity authentication process for users is essential to prevent impersonation and theft issues. However, most Metaverse platforms have security vulnerabilities resulting from reliance on central servers, or potential problems arise in which identity-related information may be disclosed in a decentralized blockchain environment. Therefore, in this paper, we propose an integrated authentication system using SBT and NFT to solve the problems of identity authentication and ownership proof of digital humans in the metaverse environment. In the proposed system, users receive SBT from the platform through KYC authentication, and identity authentication for digital humans is performed through smart contracts. This increases the efficiency of the authentication process by processing ownership and identity authentication through a single smart contract. We expect that the proposed system will allow us to build a safe and efficient digital identity management system.
