Abstract
With the rapid development of information technology, data security and privacy protection have become critical challenges for distributed systems. Blockchain technology, characterized by its decentralized nature and immutability, offers novel approaches to enhancing security and privacy in distributed databases. This study aims to explore security and privacy protection mechanisms for distributed databases based on blockchain technology, addressing the inadequacies of traditional distributed databases in data integrity, access control, and privacy protection. By thoroughly analyzing the principles of blockchain technology and its applicability to distributed databases, this research proposes an integrated blockchain-based distributed database architecture. This architecture leverages smart contracts for fine-grained access control, employs encryption algorithms to ensure secure data transmission and storage, and incorporates zero-knowledge proof technology to safeguard user privacy. Experimental results demonstrate that the proposed solution effectively resists various types of attacks while maintaining efficient data processing, significantly improving the security and privacy of distributed databases. Innovatively combining blockchain technology with the security requirements of distributed databases, this study not only resolves existing technical challenges but also provides theoretical foundations and technical support for future developments in related fields, highlighting its significance in promoting the application of blockchain technology in the domain of distributed database security.
