Research And Implementation Of Document Digital Rights Management(DRM) Technology Based On RMS

Paper documents have been replaced by Electronic documents gradually. The efficiency improved, but the risk of information misuse and leakage also has increased. Electronic information needs to be properly protected. It should be used with proper authorization. There are more and more people pay attention to digital rights management (DRM) technology. And general DRM solutions have the lack that their access control is not fine-grained. This paper researched and actualized digital rights management system based on RMS technology against this background. The main works is showed as follows.Firstly, it researched RMS technology. It explained the basis technology in RMS and the function of RMS system. And it focuses on the role that a variety of digital certificates played in RMS. It explained the process and realization of RMS technology. It analyzed the advantages and disadvantages of RMS technology, and gave solutions to the disadvantages. It discussed the encryption algorithm used in the system.Secondly, A DRM system based on RMS technology is proposed in this paper. This paper designed the system architecture. It designed the function architecture, the logical architecture, the composing and the network architecture of the system. And it described the orchestration of the system in details.At last, the system is actualized. A test environment is built. The functional testing and performance testing of the system are done. At last, this paper analyzed the advantages and disadvantages of the system.
