Design of encryption and decryption system of heterogeneous database based on Data Mining

Abstract

In view of the problem that the error rate is too high in the use of the original heterogeneous database encryption and decryption system, the original encryption and decryption system is optimized by data mining calculation, and the heterogeneous database encryption and decryption system based on data mining is designed. Through the data acquisition equipment, data storage equipment and system data transmission equipment to complete the hardware design of the system; according to the database user rights to design the database encryption dictionary, using data mining technology to complete the data preprocessing, using the form of homomorphic encryption to complete the encryption and decryption process of the database. At this point, the implementation of heterogeneous database encryption and decryption system design based on data mining. In the system test link comparing with the traditional database encryption and decryption system, by comparing the bit error rate, it is verified that the designed system can effectively reduce the bit error rate and improve the database security.
