Secure Decentralized Identity Management using Blockchain

Digital Identity Management system is important component of security infrastructure for internet applications. However, existing digital identity management systems encounter various challenges, including difficulties in cross-domain authentication and interoperation, lack of credibility in identity authentication, and vulnerabilities in the security of identity data. Despite the attention blockchain technology has garnered in the field of digital identity management and the development of blockchain-based systems, these systems have not fully resolved the aforementioned problems. To address these issues and establish a secure and trustworthy digital identity management system, this paper proposes an effective model that integrates self-sovereign identity, oracle technology, and blockchain. This model aims to provide solutions and lay the groundwork for overcoming the challenges and ensuring the construction of a secure and reliable digital identity management system.
