With the advancement in computing power and speed, the Internet is being transformed from screen-based information to immersive and extremely low latency communication environments in web 3.0 and the Metaverse. With the emergence of the Metaverse technology, more stringent demands are required in terms of connectivity such as secure access and data privacy. Future technologies such as 6G, Blockchain, and Artificial Intelligence (AI) can mitigate some of these challenges. The Metaverse is now on the verge where security and privacy concerns are crucial for the successful adaptation of such disruptive technology. The Metaverse and web 3.0 are to be decentralized, anonymous, and interoperable. Metaverse is the virtual world of Digital Twins and non-fungible tokens (NFTs). The control and possession of users' data on centralized servers are the cause of numerous security and privacy concerns. This paper proposes a solution for the security and interoperability challenges using Self-Sovereign Identity (SSI) integrated with blockchain. The philosophy of Self-Sovereign Identity, where the users are the only holders and owners of their identity, comes in handy to solve the questions of decentralization, trust, and interoperability in the Metaverse. This work also discusses the vision of a single, open standard, trustworthy, and interoperable Metaverse with initial design and implementation of SSI concepts.

翻译：随着计算能力与速度的提升，互联网正从基于屏幕的信息交互向Web 3.0与元数据中沉浸式、超低延迟通信环境转变。元数据技术的兴起对安全接入、数据隐私等连接性提出了更严苛要求。6G、区块链与人工智能等未来技术可部分缓解这些挑战。当前元数据正处于安全与隐私问题成为其颠覆性技术成功适配关键门槛的发展阶段。元数据与Web 3.0需具备去中心化、匿名性与互操作性特征。作为数字孪生与非同质化代币构成的虚拟世界，中心化服务器上的用户数据控制与持有引发了诸多安全隐私问题。本文提出一种基于区块链的自主主权身份集成方案以应对安全与互操作性挑战。自主主权身份理念——用户是其身份的唯一持有者与所有者——为元数据中的去中心化、信任与互操作性问题提供了解决方案。本研究同时探讨了基于自主主权身份概念初始设计与实现的单一开放标准、可信互操作的元数据愿景。
