Design of Heterogeneous Database Encryption and Decryption System Based on Data Mining

The main idea behind this method is to build a model to describe the relationship between encrypted data and plaintext data, as well as the relationship between the two models. This information can be used to construct an encryption key. In addition, it will help to find out which parts of plaintext are similar to some parts of encrypted data. When an application has a large amount of sensitive information, you may need to protect this information. In this case, it is necessary to encrypt all or part of the sensitive information so that only authorized users can access them. The second point is how to manage encrypted data.
