Data label traceability technology for Web layer

Abstract

The invention discloses a data label traceability technology for a Web layer, which comprises the following steps of: extracting basic data from HTTP (S) format data, and judging whether the type of the basic data is a character string type or a document type; if the data is in the character string format, automatically adding an identity feature tag into the data, encrypting the feature, processing by using an invisible feature technology, and sending the feature to a third-party service system; if the format category of the document is determined, deeply analyzing the format of the document, adding an identity feature tag to document data after successful analysis, encrypting the feature, and processing by using an invisible feature technology; leaked data is imported into matched traceability software, and the traceability software can extract identity feature label information in the data and perform decryption and visible processing on the label so as to determine the identity feature information of a specific leaked person and the time of data leakage, so that the traceability effect is realized; by means of the technical means, the data leakage risk can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of network information security, and in particular relates to a data tag traceability technology for the Web layer. Background technique [0002] Many of the current computer business systems are based on the Web, and have gradually become the mainstream. Data communication and business interaction between Web systems are basically completed in the form of calling Web interfaces. Especially for database systems and core business systems, the server web interface needs to provide various types of data for external use, such as basic data used by external third-party business systems, such as Figure 5 , Figure 6 shown. The basic data provided to external or third parties in the form of web interfaces are often of the same kind, that is, there is almost no difference in the underlying data received by different third parties. After this kind of data based on the interface level is given to multiple third-p...

Problems solved by technology

[0004] At present, there are also some means to trace the source of data identification, such as adding metadata for identification during the data storage link. On the one hand, this type of data identification needs to change the database structure and add metadata identification. On the other hand, it can only trace the data source and cannot Trace the source of the leaker

Such management and technical means can guarantee data security to a certain extent, but there are still large loopholes or chances that the basic data will be disseminated and leaked by third-party users. The main reason is that there is no difference between the basic data and the third party.

That is, the basic data obtained by third party A is exactly the same as the basic data obtained by third party B, and there is no difference in the data, which means that after any party leaks the data, it will be difficult for the data source manager to determine the specific source of the leak. Therefore, we propose a data label traceability technology for the Web layer
