Unidirectional transmission based electronic document output management and control system and method

Abstract

The invention provides a unidirectional transmission based electronic document output management and control system and method. The system comprises a terminal proxy module, a centralized management center module and an outgoing isolation module, wherein both-way communication is performed between the terminal proxy module and the centralized management center module and between the centralized management center module and the outgoing isolation module. The system has the following advantages: (1) through the unidirectional transmission technology, an in-house network is connected with peripheral output device through the outgoing isolation module, so that unidirectional output of an electronic document can be ensured, and effective isolation between peripheral output risk devices such as a printer and the sensitive in-house network is realized; (2) safe identity authentication ensures credibility of an outgoing source of the electronic document, security check ensures content controllability and manageability of the outgoing electronic document, and execution of a security policy ensures that only authorized electronic document can be sent outward; (3) multiple output modes such as printing output, optical disk burning output, storage medium output and the like are supported, and the system can be widely applied to various security output occasions of the electronic document.

Description

technical field [0001] The invention belongs to the technical field of network information security, and in particular relates to an electronic document output management and control system and method based on one-way transmission. Background technique [0002] In the modern enterprise office environment, there are a large number and various types of electronic documents. Among them, electronic documents refer to documents that rely on computer systems to access and can be transmitted on communication networks, including: electronic documents, electronic letters, electronic reports, and electronic drawings. , electronic versions of paper text documents, etc. Due to work needs, the demand for outputting electronic documents is very common. Here, electronic document output includes two types: (1) printing electronic documents as paper documents by printers: for example, printing electronic documents as paper documents, and then, Hand over the printed paper documents to the le...

Problems solved by technology

[0003] The existing electronic document output method is mainly: each employee is equipped with a terminal computer for office use, and the employee directly outputs electronic documents through various peripheral interfaces configured on the terminal computer. The main problems of this output method are: (1) output Behavior is uncontrollable: the output behavior of employees outputting electronic documents cannot be monitored, and once a leak occurs, it cannot be tracked and traced; (2) output content is uncontrollable: the content of electronic documents output by employees cannot be monitored, which may easily cause information leakage; (3 ) output devices are uncontrollable: printers and other output devices on the market have independent chips, and there is a risk of actively accessing and attacking the internal network of the enterprise, thereby stealing corporate information; And send it out through the built-in wireless module of the printer settings, resulting in information leakage
