Problems solved by technology
In business analysis, development testing, audit supervision and other use cases, sensitive data has extremely high security risks, and once leaked, it will pose a serious threat to the enterprise
The protection against data leakage is generally through data desensitization (also known as data de-privacy or data deformation). In the prior art, data desensitization generally adopts two methods, one is to add noise, but This method will change the statistical specificity of the data, and the other is sequential processing, but it uses real data, and there is still a large risk

The embodiment of the invention provides a data processing method and a data processing device. The method comprises the following steps: acquiring numerical data from a numerical data set one by one;determining a binary value of the currently acquired numerical data according to a set probability by utilizing binary distribution; and according to the binary values, determining a desensitizationmode of the currently acquired numerical data, and carrying out desensitization processing on the currently acquired numerical data in the desensitization mode, the desensitization mode being capableof maintaining the statistical characteristics of the numerical data. After the desensitization processing of the numeric data in the numeric data set is completed through the method, the desensitization data subjected to the desensitization processing can retain the statistical specificity of the original numeric data, the security risk of the leakage of the original numeric data can be reduced,and the use value of the desensitization data is improved.
Description
technical field [0001] The present application relates to the field of data security protection, in particular to a data processing method and a data processing device. Background technique [0002] At present, with the rapid growth of data caused by the convergence of information technology and economic society, enterprises collect more and more data, and the security protection of data is particularly important. In business analysis, development testing, audit supervision and other use cases, sensitive data has extremely high security risks, and once leaked, it will pose a serious threat to the enterprise. The protection against data leakage is generally through data desensitization (also known as data deprivacy or data deformation). In the prior art, data desensitization generally adopts two methods, one is to add noise, but This method will change the statistical specificity of the data, and the other is sequential processing, but it uses real data, and there are still ...
