Abstract

The invention relates to a data desensitization method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring digital sensitive data; according to a preset segmentation rule corresponding to the digital sensitive data, performing segmentation processing on the digital sensitive data; based on a preset round operation function, performing round operation of a Feistel structure on the segmented digital sensitive data to obtain a round operation result; and acquiring ciphertext data corresponding to the digital sensitive data according to a roundoperation result. According to the data desensitization method, a round function is constructed through SM4 encryption; round operation is carried out based on a round function to carry out data desensitization; the format consistency of the digital characteristic data before and after desensitization is effectively ensured; the data length, the data type and the like are not changed, so that theoriginal database storage unit can directly store the ciphertext result, the utilization rate of the encryption result is effectively improved, meanwhile, the SM4 algorithm is expanded to a reserved format encryption algorithm, and the applicability of SM4 is enhanced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data desensitization method, device, computer equipment and storage medium. Background technique [0002] With the development of computer and other technologies, people pay more and more attention to the security maintenance of network data. Data desensitization is one of the data security technologies. Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive private data. In the case of customer security data or some commercially sensitive data, the real data is transformed and provided for testing without violating system rules, such as ID number, mobile phone number, card number, customer number and other personal information. Data desensitization. [0003] At present, there is a method of desensitizing data using symmetric encryption of cryptography, but the tr...
