Problems solved by technology

However, the desensitized data obtained through traditional encryption is completely different from the original data, and maintenance personnel have no way of diagnosing data problems
Even if the format-preserving encryption method only achieves the same length before and after data encryption, it still cannot guarantee that maintenance personnel can efficiently determine data problems

Abstract

The invention provides a data desensitization and restoration method and device.The data desensitization method comprises the steps that alternative character sets are matched with characters to be desensitized in data to be desensitized, the successfully matched character sets are determined as target character sets, and each alternative character set corresponds to one or more types of characters; and according to the target character set, performing format preserving encryption FPE processing on the to-be-desensitized characters to obtain desensitized data corresponding to the to-be-desensitized data.

Description

technical field [0001] This specification relates to the field of information security, in particular to a data desensitization and restoration method and device. Background technique [0002] With the rapid development of the Internet and the advent of the era of big data, the information security of every citizen is becoming more and more important. How to carefully design information privacy protection methods to achieve a balance between information freedom and privacy protection has gradually become a problem that all major enterprises need to face together. [0003] In related technologies, before accessing a document containing user sensitive information in order to troubleshoot user data problems, maintenance personnel usually encrypt the document data, so as to achieve the purpose of data desensitization. However, the desensitized data obtained through traditional encryption methods is completely different from the original data, and maintenance personnel have no w...
