Abstract
With the rapid development of information technology, data security and privacy protection have become one of the core issues urgently needing resolution in the digital era. Blockchain technology, characterized by its decentralization, immutability, and transparency, offers a novel solution to this domain. This study aims to explore the application potential and practical effects of blockchain technology in data security and privacy protection. By integrating literature analysis with case studies, it systematically reviews the fundamental principles of blockchain technology and its specific application scenarios in identity authentication, data storage and sharing, as well as privacy computation. The findings indicate that blockchain technology can effectively enhance data security and privacy protection levels, particularly demonstrating significant advantages in data management within distributed environments. Furthermore, this research proposes a privacy-protection fr amework based on consortium blockchain, which combines zero-knowledge proof and homomorphic encryption technologies. This innovative fr amework ensures data availability while achieving effective protection of private information, showing broad application prospects in fields such as healthcare and financial transactions. Ultimately, it is concluded that blockchain technology provides a reliable technical support for data security and privacy protection; however, further exploration is required for performance optimization and standardization construction. Future research should focus on issues such as cross-chain interoperability and legal regulatory alignment to facilitate the comprehensive implementation of the technology.
