Semi-Transparent Encryption to Prevent Leakage of Sensitive Information

With the continuous progress and development of science and technology, the application of computers has been popularized in all aspects of human life, providing great flexibility for human work and study. But at the same time, computer data security is also a big problem for this booming industry. The purpose of this paper is to study semi-transparent encryption to prevent the leakage of sensitive information. A database storage encryption mechanism is discussed, and the data security storage method at the bottom of the database management system is analyzed in detail. The encryption algorithm information used by objects encrypted by the proposed semi-transparent database storage encryption (SSE) method is stored by the database management system, and the key is provided by the user connecting to the database. The storage encryption method introduced in this article allows each user to easily encrypt sensitive data, and provides users with a safe and easy-to-use database storage encryption method. In the test, semi-transparent storage encryption has basically no effect on system function and performance.
