The Research And Application Of Digital Documents Right Management System

With the trend that more and more documents are saved as digital style in computers, the information security is becoming more and more serious because that digital documents are not easily controlled and hard to trace. Improving management system is not enough for solving the problem totally. As we know, the encrypting technology can make documents safe and protect the important documents, however, the traditional encrypting technology is not efficient and cannot be finished automatically, also it cannot control its using in details.This topic is to prevent the unauthorized users use and deliver the documents. According to the above analysis, this topic put forward a kind of solution to use the transparent encryption and decryption to protect documents while we use Office plug-in to control the right of usage, these two kinds of technology are all automatic and without users’ notification. So it can not only protect documents but also can guarantee the users’ working efficiency.This system are Client/Server Structure, the client uses the transparent encryption and decryption technology while the server uses GSOAP to realize the communication and build the Web Service, the server uses SQL Server database.The combination of transparent encryption and office plug-in can strengthen the controlling and solve some problems exist in some common DRM systems such as the control of documents’circulation and record the trace of documents’using.
