Electric document anti-disclosure system and its implementing method

Abstract

The invention discloses an electronic document divulgence prevention system and a realizing method. The system essentially comprises a server and a client. The server implements an information communication with the client through a computer network. A user interface module I in the server is respectively connected with an encryption division module I, a loading key generation module and a communication module I which is connected with an encryption module I. A user interface module II in the client is respectively connected with an encryption division module II, a process monitoring module, a file monitoring module and a communication module II which is connected with an encryption module II. The realizing method of the system includes the following steps: (1) the server is initialized; (2) the client is initialized; (3) an encryption division is used for the client. The electronic document divulgence prevention system and the realizing method of the invention not only facilitate free communication of electronic documents on the network, but also effectively avoid the divulgence of the electronic documents, thus having good application prospect.

Description

Technical field: [0001] The invention relates to a system and method for preventing electronic documents from leaking, in particular to a system and method for preventing electronic files from leaking in computer networks. Background technique: [0002] With the popularization and deepening of computer applications, as well as the continuous development of government and enterprise informatization, more and more important materials are stored in the form of electronic documents, and information interaction is gradually using electronic documents. Finish. The development of the computer Internet and various portable storage devices provides convenient means for the exchange and circulation of electronic documents. How to ensure the safety of confidential electronic documents containing important information in terms of use, transmission, and storage has gradually become a key issue in the process of informatization in various departments. [0003] However, due to the conven...

Problems solved by technology

It is not suitable for occasions that require a large number of file processing locally on the client, such as local compilation of software, etc.

Furthermore, it does not prevent active disclosure by authorized users and active disclosure by document authors

[0008] There are still the following disadvantages in the existing anti-leakage technology: convert the electronic file into a specific file format and then encrypt it, and then use it through authorization control. This method has too strict restrictions on the format of the protected document. If the file format cannot be converted, it cannot It is not suitable for the protection of general files; the method of using a special reader for encrypted files, due to the restrictions of the reader, not only the supported file formats will be limited, but also the flexibility of using encrypted files will be affected; although in some methods File rights management is also applied in , but the function of rights management is relatively simple; the use of encrypted files does not fully support encrypted editing, that is, when editing encrypted files, the operation of the file cannot be controlled, and the content of the file is easily leaked

[0012] In addition to monitoring file operations and process operations, the transparent encryption system also needs to prevent leaks caused by operations such as clipboard, screen recording, and screenshots. Completing a complete system requires a lot of work and is very easy to crack

[0013] In short, there are certain limitations in the existing various electronic document anti-leakage methods.
