Abstract

Digital Rights Management (DRM) is a technology to protect digital rights from unauthorized access and to control the content throughout its entire life cycle. In mobile environment, besides of the traditional demands of persistent copyright protection, some characteristics such as easier to access and low computing energy of mobile devices should be considered. There have been many previous sophisticated solutions for this issue. In this paper, we concentrate on how to efficiently solve the inconvenient problem faced by customers, which is caused by lack of interoperability between DRM systems. We propose a scheme to realize exchanging digital right information between diverse DRM systems by ahead establishing trust relationships among Right Issuers (RI) so that to provide an more efficient, convenient and uniform contents interface for customers, based on secure technical consideration.
