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...

Embodiment Construction

[0079] The present invention is described in detail below in conjunction with accompanying drawing:

[0080] The present invention provides an electronic document output management and control system based on one-way transmission. The core idea includes the following points:

[0081] (1) Centralized output path: Centralize the terminal electronic document output channels to a unified output isolation device for output, which is convenient for centralized monitoring and control, and avoids the risk of discrete output of each terminal;

[0082] (2) Controllable data output: conduct security checks and audits on the content of all output electronic documents to avoid the output of non-compliant electronic documents;

[0083] (3) Safe output path: Through the special design based on one-way transmission, the internal network and the peripheral output device are effectively isolated through the outgoing isolation device;

[0084] (4) Output behavior audit: provide full audit of th...
