Secure domain architecture for interoperable content distribution

Abstract

Authorized domains are used to share digital content among multiple devices without violating the copyright issues. However, if a domain is composed of multiple devices supporting different DRM technology, sharing and accessing of contents among the multiple devices in a domain may not be possible. To address this issue, in this paper we propose a new secure domain architecture which uses a Local Domain Manager (LDM) and T-licenses for achieving interoperability. The LDM serves as a middle entity that handles the distribution of interoperable domain content to all the registered domains according to the T-Licenses provided by the respective content providers. Thus, the proposed domain architecture enables secure sharing and accessing of digital content in an authorized domain. © 2009 Springer-Verlag Berlin Heidelberg.
