Embodiment 1

[0034] Step 1, as shown in Table 1, is the digital field of the user code selected from the statistical database of the enterprise unit within the jurisdiction of a certain place:

[0035] Table 1

[0036]

[0037] At the same time, the data was shared among multiple functional units such as Bureau A, Bureau B, and Bureau C during the sharing process. During the sharing process, the database will automatically record the process information as shown in Table 2:

[0038] Table 2

[0039]

[0040] Step 2: Extract the recorded information from the system database on the whole process of delivery, transfer, and operation of data sharing, such as: extract the data of Bureau C of the delivery department15, extract the data of the operator Li XX, and extract the data of the operation date October 2021 On the 27th, extract the operation time data at 9:15;

[0041] Step 3: Transform the data in step 2 into class structures, unify the data types, convert the information of deliv...

Abstract

The invention relates to a digital confusion marking algorithm and belongs to the technical field of data leakage prevention. The digital obfuscation mark algorithm extracts the digital fields in the database and the information of data delivery, transfer, and operation, generates a confused non-image digital watermark after class structure transformation, array reconstruction change, elliptic curve operation, and static data conversion, and Write it back to the database, and in the event of a data leak, extract the digital watermark from the leaked data, trace the source of the data through reverse operations, and find out the point of the data leak. The digital obfuscation algorithm designed by the present invention is applied to the data leak prevention system when data is shared across departments and units, and can effectively trace the source and generate a leak evidence chain after a leak occurs.

Description

technical field [0001] The invention relates to the technical field of data leakage prevention, in particular to a digital confusion marking algorithm. Background technique [0002] In recent years, all provinces and cities across the country have approved the establishment of big data bureaus. The main responsibility of big data bureaus is to complete data sharing and data mining among various departments such as governments at all levels, enterprises and institutions, and provide a basis for management decisions. Cross-departmental data sharing is a new thing. For this new form of data sharing, it is urgent to invent a method for the data leakage prevention system to trace the source of data. [0003] Existing data leak prevention methods still mainly rely on traditional firewall products at the network layer and hardware layer. In addition to hardware products, there is no technical means based on the underlying software or algorithm level of the database to prevent data...
