Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with specific embodiments.

[0015] Such as figure 1 As shown, the structure diagram of the document security system based on the micro-filter drive model of the present invention includes a micro-filter drive module (transparent encryption kernel) and a management control module. The management control module configures operating information for the micro filter drive module, performs document key management, LAN sharing management, and mobile disk access control. The management control module includes a micro filter drive control unit, a LAN sharing management unit, a USB Key management unit, and mobile Disk access control unit. The micro filter drive control unit and the micro filter drive module communicate through a port communication mechanism, and the local area network sharing management unit, the USB Key management unit, and the mobile disk access control unit communicate with the micro filter ...

Abstract

The invention discloses a document security system based on a microfiltration drive model, which comprises a microfiltration drive module and a management control module, the management control module comprises a microfiltration drive control unit, a local area network sharing management unit, a USB (Universal Serial Bus) Key management unit and a mobile disk access control unit; and the microfiltration drive control unit is communicated with the microfiltration drive module through a port communication mechanism, the local area network sharing management unit, the USB, the Key management unit and the mobile disc access control unit are communicated with the microfiltration drive module through the microfiltration drive control unit. The system provides document protection for Microsoft office software on a Windows NT platform, and prevents documents from leaking.

Description

Technical field [0001] The invention relates to a computer electronic document protection system, in particular to a document security system based on a micro-filter driving model, which mainly provides protection for Microsoft Office 2003 / 2007 documents. Background technique [0002] At present, the mainstream document protection system is implemented based on the traditional filter driver model. The main structure of the system is to load a filter driver at the kernel layer and design the control program at the application layer. The filter driver at the kernel layer can provide transparent encryption and transparent decryption functions for data upon request. The user-level control program controls the transparent encryption and decryption kernel according to the system settings. The kernel driver and the upper-level control program cooperate with each other to provide protection for the document. The transparent encryption kernel based on the traditional filter driver has pr...
