Problems solved by technology

[0008] figure 1 Although the offline verification method shown can realize the user's permission restriction by setting the allowed number of prints, but because the user can copy or even spread the document to be printed on the network at will, the actual number of times the user can print becomes " Number of copies × allowable printing factor", which is equivalent to no limit
It can be seen that the existing offline verification method cannot guarantee the security of the document

Embodiment Construction

[0092] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0093] In the embodiment of the present invention, the document is registered in advance, and the printing control information of the document is stored; when the document needs to be printed, the printing control information of the document is obtained, and the authority verification is performed on the document according to the printing control information, and the execution is executed after the verification is passed. print operation.

[0094] To register a document is actually to save the printing control information of the document. The printing control information mentioned here is mainly composed of two parts, namely the document identification as the document identification information, and the number of copies allowed to be printed, the printin...

Abstract

An embodiment of the invention discloses a method of realizing off-line print constraint, comprising: registering documents in advance, storing print control information of the document; obtaining the print control information of the document when being required to print the document, performing right verification according to the print control information, and printing the document after verification. An embodiment of the invention also discloses a system of realizing print constraint. According to the method and the system in the embodiment of the invention, security of printing the document under off-line state is ensured.

Description

technical field [0001] The invention relates to document operation authority control technology, in particular to a method and system for realizing offline printing restriction. Background technique [0002] The current official document or document management systems all have the requirement of restricting the permissions of the documents to be processed by users. For example, if a user obtains a document, even if the document has left the document system, it is still necessary to control the permissions of the document, such as not allowing the user to print at will, and so on. [0003] In the prior art, the document permission limitation method usually adopted is the network verification method, that is, when the user needs to print the document in hand, the printing program first goes to the server to verify online whether the user has the permission to print the document, and if so, prints ; otherwise, refuse to print. Although this method achieves user authority rest...
