Abstract

The invention discloses a database encryption and complete matching retrieval system, and relates to the technical field of data encryption and matching retrieval. The system comprises a data encryption and storage module and an encrypted data query module, the data encryption and storage module comprises an encryption algorithm initialization unit, a data encryption execution unit, a ciphertext data visualization unit and an encrypted data storage unit; and the encrypted data query module comprises a query receiving unit, a query analysis unit, a data encryption and decryption unit, an encrypted data visualization unit and a query result return unit. According to the method, the existing symmetric encryption algorithm is combined with the own visualization algorithm, so that the high security of data storage can be ensured, and the ciphertext data can be ensured to be quickly matched by using the database index during complete matching query; according to the method, the retrieval efficiency of the ciphertext data in a business scene with complete matching query as a main part is improved, and particularly, the user experience can be greatly improved under the condition of mass data.

Description

technical field [0001] The invention belongs to the technical field of data encryption and matching retrieval, in particular to a database encryption and complete matching retrieval system and method. Background technique [0002] There are three most commonly used methods for personal information protection: encrypting and storing personal information in databases; implementing data leakage prevention through database firewalls; and covering up personal information through data desensitization. Among them, the first method can ensure that the data before encryption cannot be parsed even if the database data is stolen, so it is widely used. [0003] Major data security vendors on the market have launched database encryption products. These products not only ensure the security of data storage, but also change some attributes of the data in the database (comparability, order, similarity), which makes encrypted It is difficult for existing databases to meet the complex and di...
