Research on the Application of Blockchain Technology in the Construction of User Privacy Information Security Model
Ji Lai, Shijun Zhang, Shuo Li · 2023
User privacy security issues not only threaten the personal information security of blockchain technology, but also become the biggest bottleneck and obstacle restricting the development of big data technology. When there is big data leakage about personal privacy, it is not only a leakage of privacy, but also a prediction based on big data on the behavior status of the leaked privacy individuals. This article further studies the security of user privacy information through blockchain technology. The research results indicate that cloud identity authentication systems based on global variables exhibit significant fluctuations in data variance values, resulting in poor data integration performance; The data fluctuation of cloud identity authentication system based on virtual stack is relatively small, and its data integration performance is average; The cloud identity authentication system based on blockchain technology has the smallest data fluctuation, indicating that the method proposed in this article performs the best in data integration performance among three experimental systems. Decentralization of blockchain technology to coordinate related tasks. In distributed systems with low trust, it can be reflected, which can to some extent ensure the security of the network space.
