Embodiment Construction

[0015] The invention performs mark operation on the document by combining various technical means, and the marked document can be read and written transparently under the invocation of a legal process.

[0016] The present invention is divided into a three-layer structure: a driver layer, an intermediate layer, and an application layer.

[0017] The driver layer provides the underlying file filtering process, including the file filtering driver.

[0018] The middle layer provides information acquisition interface, file capture, policy configuration and middleware interface required for identification, including file operation hook module, identification middleware module, and identification information interface module.

[0019] The application layer realizes specific logo operation and display through functional programs, embedding Explorer and document editing software, including icon processing module, right-click menu module, document embedded logo module, and window suspe...

Abstract

The invention discloses a file transparent identification method based on an application program file operation hook. When a file filter driver implements an identification applying operation and an identification removing operation, all file operations must pass the file filter driver; therefore a loophole that illegal courses break documents is effectively avoided; moreover, by applying the method, all file creation operations can be processed by Hook, so that the forced identification is implemented; as a result, all newly-created documents in a computer which is provided with the system are identification documents; a user cannot process common documents; real document contents and identification information can be viewed only through a legal course.

Description

technical field [0001] The invention relates to the technical field of document transparent identification, in particular to a file transparent identification method based on an application program file operation hook, through which the document is marked and read and written transparently. Background technique [0002] Document identification technology is currently generally used in special field markets for document identification control, such as documents issued by party and government agencies, enterprises and institutions involving commercial confidential documents, etc., but there is no standard definition of specific rules for document identification in the market. There is also no mature solution for its implementation. [0003] At present, the existing document identification products on the market only identify documents at the application layer, that is, the operations of labeling and de-identification of documents are performed at the application layer. As long...
