Abstract: Today’s technology is raising important challenges in the Intellectual Property (IP) field in general and to Copyright in particular [Arkenbout et al., 2004]. The same technology that has made possible the access to content in a ubiquitous manner, available to everyone in a simple and fast way, is also the main responsible for the challenges affecting the digital content IP of our days [Chiariglione, 2000]. Technological solutions and legal frameworks were created to meet these new challenges. From the technological point of view, Rights Management Systems (RMS) and Copy Protection Systems (CPS) have been developed and deployed to try to cope with them. At first, they seemed to work however, their closed and non-interoperable nature and a growing number of wrong strategic business decisions, soon lead to a strong opposition. One of the strongest negative points is the lack of rights management interoperability [Geer, 2004]. The work presented on this thesis primarily addresses the RMS interoperability problems. The objective of the thesis is to present some possible mechanisms to improve the interoperability between the different existing and emerging rights management platforms [Guth, 2003a]. Several different possible directions to rights management interoperability are pointed in this thesis. One of the most important is openness. Interoperability between different rights management mechanisms can only be achieved if they are open up to a certain level. Based on this concept, an open rights management platform is designed and presented in this thesis. Also, some of the interoperability mechanisms are presented and explained. This platform makes usage of the emerging service-oriented architectures to provide a set of distributed rights management services. Rights management solutions rely heavily on the establishment of authenticated and trust environments between its different elements. While considering different RMS, the establishment of such trust environments can be somehow complex. This thesis provides a contribution to the establishment of interoperable RMS trust environments through the usage of Public-Key Infrastructure (PKI) mechanisms. Modern rights management systems have to handle with both keying material and licenses which are used mostly to define how content is governed by the system. Managing this is a complex and hard task when different rights management solutions are considered. This thesis presents and describes a generic model to handle the key and license management life cycle, that can be used to establish a global interoperable management solution between different RMS.
