Abstract

The invention discloses a system and a method for on-line separation and recovery of electronic documents, and aims to realize automatic separation storage and recovery of electronic documents during the editing and using processes without any influence on thespecific document editing system. The method comprises the steps of binding a part storage area of a management terminal and a part storage area of a special key board (customized by the system) to form a logic storage space, namely, ''separation storage area''; when preserving the file in the separation storage area, effectively separating and storing information to two different mediums, namely, the management terminal and the special key board; when reading the file in the separation storage area, acquiring recovered original document by document fragment information on two mediums. Compared with the traditional encryption management, the method is more safe, convenient and reliable, so that the method can provide a safety management tool with super strength for terminal-level electronic documents.

Description

technical field [0001] The invention relates to a security management system for electronic documents, in particular to a system for online separation and recovery of electronic documents, and belongs to the technical field of information security management; the invention also relates to the method for online separation and recovery of electronic documents. Background technique [0002] The security protection of electronic documents is one of the core issues of information security. There are a series of software and hardware systems and methods for its security management, but the technical means used mainly include the following methods. [0003] (1) Access control based on identity authentication. Typically, the server centralized storage method is adopted. After the client has the server to authenticate the user identity, the client is granted corresponding permissions, such as reading, writing, copying, and deleting. [0004] ⑵Encrypted storage method. Files are enc...
