Method and system for changing operation authority of outgoing file

Abstract

The invention provides a method and a system for changing operation authority of an outgoing file. The method comprises the steps of firstly, obtaining a claimant message of the outgoing file and an authority changing message of the outgoing file, wherein the authority changing message comprises at least one authority message after the changing is requested; secondly, comparing each obtained authority message with the corresponding maximum authorization message that a claimant can process the outgoing file, generating authorization messages based on comparison results, and sending authorization messages; finally, changing the operation authority of the claimant according to obtained authorization messages, so that the claimant can operate the outgoing file. Thus, the operation authority of the outgoing file can be controlled flexibly, and the problem that the operation authority of the outgoing file can not be changed anymore once the operation authority of the outgoing file is set.

Description

technical field [0001] The invention relates to an authority control scheme for outgoing files, in particular to a method and system for changing the operating authority of outgoing files. Background technique [0002] With the development of informatization, most of the documents between enterprises or within enterprises are stored and transmitted in the form of electronic files. Prevent outgoing electronic documents from being leaked. At present, the method of setting the operation authority of the external file is mainly to convert the external file into a preset format, and embed the operation authority into the header of the corresponding format through an encryption algorithm, so as to monitor the operation of the external file. [0003] However, in the above approach, once the outgoing file is issued, the operating authority of the outgoing file cannot be changed. In practical applications, the operating authority of the outgoing file may not be able to meet the oper...
