Space Authentication in the Metaverse: A Blockchain-Based User-Centric Approach

As the metaverse continues to gain traction, the importance of research into metaverse security becomes increasingly evident. While there has been notable research on authenticating users within the metaverse, there remains a gap in the authentication of specific spaces within this virtual environment. This paper aims to address this gap by introducing a novel user-centric blockchain-based authentication method that incorporates space authentication. The proposed approach utilizes blockchain smart contracts to authenticate users through cosine similarity metrics. This method offers significant advantages by seamlessly integrating metaverse and blockchain technologies, all without the need for a centralized authority. One notable feature of this approach is its ability to establish user-centric authentication, ensuring security while users navigate different spaces within the metaverse.
