Embodiment 1
[0061] A watermark traceability method for identity card data desensitization, such as figure 1 shown, including the following steps:
[0062] S1: Extract data from the data source, compare the data with ID card rules, find the ID card rule field in the data source, and desensitize according to the data desensitization rules.
[0063] Discover specified ID card information through the automatic discovery function of data desensitization, or specify the source of ID card information by adding a specific data desensitization source.
[0064] S11: Connect to the corresponding data source according to the data source information, obtain data from the data source and put it into a set, compare the ID card rules for each piece of data in the set, and obtain the ID card rule field.
[0065] S12: Desensitize the data that conforms to the ID card rules according to the data desensitization rules, perform data desensitization error processing on the non-compliant data, and exclude dirt...
Embodiment 2
[0101] A watermark traceability method for ID card data desensitization, using Chinese Unicode codes to correspond to a data source. The watermark information can be extracted with less data, and the data source can be found.
[0102] This embodiment is the same as the first embodiment except that the four watermark numbers are replaced by Chinese Unicode codes.
