ABSTRACT
With the rapid development of information technology, identity authentication faces numerous challenges such as privacy breaches and data silos. Constructing a decentralized identity authentication system based on blockchain technology has emerged as a novel approach to address these issues. This study aims to design and implement a blockchain-based decentralized identity authentication system to enhance the security and privacy protection of identity verification processes. By thoroughly analyzing the characteristics of blockchain technology and integrating cryptographic techniques such as zero-knowledge proofs and homomorphic encryption, this research proposes an identity authentication architecture that combines on-chain and off-chain collaborative mechanisms. This architecture enables users to autonomously manage their identity information, ensuring data authenticity while achieving efficient authentication procedures. Experimental results demonstrate that the proposed system not only maintains high security but also effectively reduces verification latency, thereby improving user experience. Moreover, the system supports cross-platform interoperability, providing unified identity authentication services for various application scenarios, with excellent scalability and compatibility. It offers a new solution for building a secure and trustworthy network environment. The innovation lies in the deep integration of blockchain technology with modern cryptography, pioneering a new model in the field of identity authentication.
