Data desensitization processing method and device and storage medium

Abstract

The invention discloses a data desensitization processing method and device and a storage medium, and the data desensitization processing method comprises the steps: obtaining a to-be-desensitized character string; traversing each character in the to-be-desensitized character string, and determining a part of continuous characters in the to-be-desensitized character string of which the number of the continuous characters exceeds a preset digit and the character type is a number as a to-be-desensitized array string; in the to-be-desensitized array string, replacing continuous characters with preset digits from a preset initial position with preset digits to generate a desensitized array string, and storing the desensitized array string; replacing non-reserved characters in the non-ASCII characters in the to-be-desensitized character string with preset covering characters, and storing the non-reserved characters, the non-reserved characters being randomly determined; and generating a desensitized character string according to each character stored in the result buffer area. According to the embodiment of the invention, the characters are desensitized by identifying the characters inthe to-be-desensitized character string, and the data format does not need to be defined in advance, and meanwhile, the characters are traversed, so that the desensitization sufficiency and integrityare ensured.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data desensitization processing method, processing device and storage medium. Background technique [0002] Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive private data. Usually, without violating system rules and conditions, real data such as data related to customer security or some commercially sensitive data are transformed and tested, such as ID number, mobile phone number, card number, customer number and other personal information can be tested Data desensitization processing. This allows safe use of masked real-world datasets in development, testing, and other non-production environments, as well as outsourced environments. [0003] In the prior art, sensitive data is mainly processed by defining the data format in advance or based on natu...

AI Technical Summary

Problems solved by technology

Once desensitized, the data cannot be traced back

However, after desensitizing the sensitive data through the existing technology, the original data format changes

For example, after desensitization, the mobile phone number 13812345678 becomes fb9b5908054fb6b5659c85df7151188d, and the type and meaning of the original data cannot be known, which makes it impossible to conduct qualitative analysis on the desensitized data
