Embodiment Construction

[0058] The present invention is an electronic document security management system and method. The core technology of the system is the driver management on the client side, running in the core state of the Windows operating system, and called by the I / O manager to meet the system's requirements for the file system; the system The data encryption platform will take over the file system of the entire Windows operating system, and is responsible for providing real-time transparent data encryption and decryption services for the file system.

[0059] When an application that needs to be controlled is running, the driver will monitor the I / O actions of the program. When the application performs a file write operation, the system will automatically encrypt it and then hand it over to the lower device driver to complete Actual disk write action.

[0060] When a read action is detected, it first identifies whether the file is an encrypted file, and if it is an encrypted file, it autom...

Abstract

The invention discloses an electronic document safety management system and method. The electronic document safety management system comprises a driving layer transparent encryption and decryption module, an application layer safety control and transparent encryption and decryption module, an intelligent file and process characteristic identification module, a file outside issuing off-line control module, a file screen watermark and printing watermark control module, a safety strategy management module and a secret key management module. The core technology of the system is managed in the driver of a client terminal, is operated in the core of the Windows operating system, and is called by an I/O manager to meet the demand of a file system. A data encryption platform of the system will take over the file system of the whole Windows operating system, and is responsible for providing the transparent encryption and decryption data services for the file system in real time. According to the electronic document safety management system and method, due to the fact that the electronic file safety protection measures are improved and the transparent encryption and decryption methods are imported, the off-line high safety and user friendliness of the electronic files are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of digital content security, in particular to an electronic document security management system and method. 【Background technique】 [0002] With the rapid development of modern technology, it has brought many fundamental changes to all aspects of social life. With the development of computer technology and office automation technology, electronic documents have emerged as the times require. [0003] The so-called electronic documents refer to files and files generated in digital equipment and environment, stored in digital form on tapes, disks, CDs and other carriers, relying on digital equipment such as computers to read, process, and transmit on communication networks. The advent of electronic documents has transformed documents and archives from "tangible" to "intangible", bringing vigor and vigor to archives work, but at the same time it also poses new challenges to archives work. Among them, the sec...
