Embodiment Construction

[0033] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] A watermark processing and data traceability method based on original data deformation, such as figure 1 shown, including the following steps:

[0035] Data initialization: extract the specified data set from the original data and generate a data subset;

[0036] Sensitive data identification: identify sensitive field attributes in original data according to sensitive data configuration rules;

[0037] Watermark processing: Transform sensitive data according to the policy configuration rules, and realize the embedding of data watermark information;

[0038] Data traceability: Input sample data for watermark extraction and data deformation, and perform data traceability based on watermark marks.

[0039] The processing procedure of the present invention will be described below by taking the employee's basic information as an example. ...

Abstract

The invention relates to a method for processing watermarks and tracing data on the basis of original data deformation. The method is technically characterized by comprising extracting data from raw data with a plurality of tuples to form data subsets S; identifying sensitive data in the data subsets S to obtain sets C of tables with sensitive attributes; processing the watermarks for the data sets C; inputting sample data, extracting data watermarks and tracing the data according to extracted watermark information. Attributes of tables in the data subsets S contain sensitive information. Themethod has the advantages that the method is reasonable in design, and the safety protection capability in data sharing procedures can be improved; the data watermarks can be embedded on the basis ofthe data deformation, the leaked data can be traced on the basis of the data deformation, and accordingly the method can be used in extensive application scenes.

Description

technical field [0001] The invention belongs to the technical field of database security, in particular to a watermark processing and data traceability method realized based on original data deformation. Background technique [0002] Digital watermarking technology is a kind of information hiding technology. It embeds watermark information directly into the digital carrier, which does not affect the use of the original carrier and is not easy to be noticed. Through these embedded information, the purpose of confirming the copyright owner, proving whether the carrier has been tampered with, and tracking the leaking user can be achieved. Early digital watermarking technology mainly focused on image and audio multimedia watermarking. In recent years, with the increasing prevalence of big data, the research on watermarking technology in relational databases has become more and more important, and the data-based watermarking technology has gradually reflected its application val...
