Abstract: At present, most mobile terminals haven’t any functions of rights management, and cryptology-based method can’t resolve all the copyright problems in mobile digital distribution service. With the urge demand of digital rights management in digital distribution service, a scheme independent of terminals is proposed in this paper. It integrates watermark and signature techniques. In the paper we mainly discuss the scheme theory, architecture, service process and performance. In the end, the functional relationship between the proposed DRM and cryptology-based OMADRM is given. Analysis shows that the scheme is feasible and secure.
