Research on Electronic Data Security and Privacy Protection Mechanism Based on Blockchain Technology

With the theme of “Research on electronic data security and privacy protection mechanism based on blockchain technology”, this paper explores the innovative application of blockchain in ensuring electronic data security and privacy protection. This paper proposes a novel framework that combines functional encryption and zero-knowledge proof mechanisms to address the current challenges in the field of data protection. Through the carefully designed algorithm, this paper realizes the efficient processing of the data in the encrypted state, and ensures the privacy and integrity of the data. The application of zero-knowledge proof technology allows the verification of data operations without disclosing sensitive information, which further improves the security of the system. In order to verify the effectiveness of the mechanism, this paper builds a model and conducts a detailed simulation test. The results show that the system has stable performance, significant data protection effect, an error rate of less than 0.05%, and an average response time of 0.2 seconds when processing a large amount of data, which proves the feasibility and high efficiency of the framework in practical applications. This study provides a new idea and method for the protection of electronic data privacy, which has important theoretical and practical value.
