A New System Model of ERDRM Based on Tamper-resistant Technology

摘要

Although the Digital Rights Management of Education Resources (ERDRM) has developed greatly these years, there are still many problems, such as the conflict of the rights-protected and the resources-shared, especially under the network environment. And by now there is still no good method to solve the problem. So in this thesis, we design a new system model, and introduce the performing flow of the system. With the system, the education resource can be used freely and not be modified arbitrary in the network environment. The system is based on the technology of the core embedded tamper-resistant and the digital watermark, which both play an important part in the information safety.
