Abstract

The invention provides a format-reserved data encryption method and system. The method comprises a limiting configuration step: setting encryption limiting configuration for reserving an original format of data for the data; and a data encryption step: encrypting the data according to the encryption limit configuration; wherein the limiting configuration step comprises a position limiting step ofdetermining an encryption position in the data so as to encrypt the data at the encryption position. According to the invention, detailed definition is carried out on the required encryption effect, including the specific change range of the data, the changeable digit of the data and other information, so that the encrypted data is kept consistent with the original data in both the data format andthe data range.

Description

technical field [0001] The invention belongs to the field of data encryption, in particular to a data encryption method and system with format preservation. Background technique [0002] At present, frequent data security leaks have created legal risks and credit crises for enterprises. Countries are also constantly improving and promulgating corresponding laws and regulations related to data security, requiring and restricting enterprises to protect data in the process of data collection, storage, and use. Security, which requires enterprises to encrypt or desensitize the collected and stored sensitive data. However, in application scenarios such as data verification and data analysis, if the data format is changed, program errors or related data analysis cannot be performed. It is necessary for the data to retain the original format after being encrypted or desensitized, which not only ensures the security of the data but also avoids the problem of program bugs caused by d...
