Embodiment 1

[0047] Based on the above ideas, see figure 1 As shown, Embodiment 1 of the method for desensitizing sensitive data of the present invention includes the following steps:

[0048] Step 101: Select N data records from the M data records, and record the data positions of the N data records, where N and M are integers greater than 0, and N is smaller than M.

[0049] Assuming that the total amount of original data is M data records, the M data records can be saved in the database or in a database export file.

[0050] In some embodiments of the present invention, the specific realization of selecting wherein N data records from the M data records may include:

[0051] Sequentially select the 1st to the Nth data records among the M data records.

[0052] When the first to Nth data records among the M data records are sequentially selected, the data positions of the N data records are recorded, and the first N data records can be marked by directly recording the value of N.

Abstract

The invention discloses a method for removing sensitivity of sensitive data, and the method is used for improving efficiency of removing the sensitivity of the sensitive data and for reducing required additional storage expenses. The method includes the steps of selecting N data records from M data records, recording data positions of the N data records, storing sensitive data contained in the N data records into a set linear memory cache, exchanging sensitive data contained in each unselected data record of the M data records with sensitive data contained in a random data record in the linear memory cache, enabling sensitive data contained in N data records in the linear memory cache to replace the sensitive data contained in the original N data records in the recorded data positions after exchange is conducted, wherein both N and M are integers larger than 0, and N is smaller than M. The invention further discloses a device for removing the sensitivity of the sensitive data.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for desensitizing sensitive data. Background technique [0002] With the development of informatization, a large amount of sensitive raw data is often stored in the databases of some industries, such as names, addresses, telephone numbers, ID numbers, amounts, etc. If these data are leaked, it will cause serious harm to enterprises or individuals. Bad influence. At the same time, testing data is the basis of testing database work. Since a large amount of sensitive data is stored in the database, when constructing the test environment, these data need to be "desensitized" to make the data in the test environment lose sensitivity. , to avoid leakage of sensitive data during data testing. [0003] In the prior art, desensitization of sensitive data can be performed by obfuscation, that is, all sensitive data is disrupted and stored in the original locat...
