Abstract

The invention is applicable to the technical field of information security, and particularly relates to a data encryption method and device based on information security, terminal equipment and a medium. According to the method, to-be-encrypted data is subjected to desensitization processing and differential privacy processing, so that local desensitization and local differential privacy of the to-be-encrypted data are realized, and the desensitized data and the differential privacy processed data are two different data obtained by using different privacy processing methods. Because the two kinds of different data are not associated, even if the original data of the two kinds of different data are obtained through corresponding reverse engineering, the original data of the two kinds of different data are not associated, so that the to-be-encrypted data cannot be accurately obtained according to the original data of the two kinds of different data; therefore, the secrecy effect of the to-be-encrypted data is improved, and leakage of the to-be-encrypted data is avoided.

Description

technical field [0001] The present application belongs to the technical field of information security, and in particular relates to a data encryption method, device, terminal equipment and medium based on information security. Background technique [0002] At present, cloud computing and mobile Internet technology and applications are becoming more and more mature, and data sharing is also the general trend. At the same time, data security issues are becoming increasingly serious, especially the most confidential or sensitive information, such as ID numbers, mobile phone numbers, bank card numbers and other financial information. , facing the risk of privacy leakage, and the existing technology uses the method of hiding part of the information to achieve secrecy, the logic of this method is simple and easy to be cracked, therefore, the secrecy effect is poor. Contents of the invention [0003] The embodiments of the present application provide a data encryption method, dev...
