Fernando Figueira Filho, João Porto de Albuquerque, Paulo Lício de Geus, Heiko Krumm · 2007
Through the past years, several digital rights man- agement (DRM) solutions for controlled dissemination of dig- ital information have been developed using cryptography and other technologies. Within so many different solutions, however, interoperability problems arise, which increase the interest on integrated design and management of these technologies. Pursu- ing these goals, this paper presents a framework which aims at promoting interoperability among DRM systems, using a service- oriented architecture (SOA) and a high-level policy modeling approach.
