Document safety control method, device and system

Abstract

The invention provides a document safety control method, a document safety control device and a document safety control system. The method comprises the following steps that: an application proxy acquires a document to be encrypted and generates an encrypted document according to the document to be encrypted; and the application proxy saves the key of the encrypted document to a document safety server and transfers the encrypted document to an application system. The application proxy automatically encrypts the document when acquiring the document to be encrypted, so that the encryption process can be automated and transparentized; meanwhile, users do not need to modify every process of the application system, the method is simple and practicable and has high universality, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of security control, in particular to a document security control method, device and system. Background technique [0002] The popularity of the Internet has made it easier to obtain, share and disseminate information, but it also increases the risk of important information leakage. There are two main types of existing document security protection technologies: encrypted storage and fine-grained authority control. For encrypted storage, after the document is encrypted, unauthorized persons cannot use it even if they get it; for fine-grained authority control, because it can set the user's access authority to the document in advance, such as read-only, modify, copy, print, screen copy , screen recording, etc., so on the basis of ensuring the normal use of the document, it can prevent the document from being illegally leaked. The above two electronic document security protection technologies are mainly composed of a d...
