Encryption document outgoing control system and method on basis of B/S (Browser/Server) framework

Abstract

The invention discloses an encryption document outgoing control system and method on the basis of a B / S (Browser / Server) framework. The system comprises a document encryption system, a user management system, an outgoing control system, and WEB application service. The system adopts the mature B / S framework at present to store encryption documents in a document server, and establishes a small WEB server to provide WEB service. The encryption document outgoing control system and method provided by the invention can reduce troubles in document outgoing due to system instability; and the system can perform concentrated control on the outgoing documents, thereby avoiding the conventional distributed and uncontrollable way. As encryption and decryption of the documents are performed in a company, the controllability and the management on the documents are more effectively ensured, and the safety of the documents is higher, so that the system and method have the inevitable advantage in the aspect of avoiding antivirus software.

Description

technical field [0001] The invention belongs to the technical field of computer network communication security, and in particular relates to a B / S framework-based encrypted document outbound control system, and at the same time, the invention also relates to a B / S framework-based encrypted document outbound control method. Background technique [0002] In the existing intranet document security management, the files are encrypted and protected, which better improves the security of the company's intranet documents; in actual work activities, there are a large number of documents that need to be opened to the outside world to facilitate the company's external activities. Most document exchanges are transmitted through email attachments or peer-to-peer application software. For example, there may be unsafe factors in the transmission of plain text, and the outgoing file may be resent to a third party by the other party, resulting in file misuse and disclosure; Then it may not ...

[0002] In the existing intranet document security management, the files are encrypted and protected, which better improves the security of the company's intranet documents; in actual work activities, there are a large number of documents that need to be opened to the outside world to facilitate the company's external activities. Most document exchanges are transmitted through email attachments or peer-to-peer application software. For example, there may be unsafe factors in the transmission of plain text, and the outgoing file may be resent to a third party by the other party, resulting in file misuse and disclosure; Then it may not be able to read normally; in the prior art, the key and control information are written on the plug-in, and are bundled with the outgoing encrypted document, and sent to a third party, and the other party runs the plug-in normally, and the encrypted file can be opened and read normally. Use, and at the same time effectively control the printing, modification, editing, screen capture, etc. of the document; this method is complicated, inconvenient, and unsafe. The document opened under the download is out of control, etc., which will affect and trouble the normal communication between companies
