摘要:

At present, most mobile terminals do not have any functions of rights management, and the cryptology-based method cannot resolve all the copyright problems in the mobile digital distribution service. With the urgent demand of digital rights management in digital distribution service, a scheme independent of terminals is proposed in this article. It integrates the watermark and signature techniques. In this article the scheme theory, architecture, service process, and performance are mainly discussed. In the end, the functional relationship between the proposed digital rights management (DRM) and the cryptology-based open mobile alliance digital rights management (OMA-DRM) is given. The analysis shows that the scheme is feasible and secure.
