Rights and trust in multimedia information management

Abstract

Multimedia information management, which implies all steps from creation and production to distribution and consumption, is a complex and challenging research area. To have a secure and trusted system we need to take into account aspects such as digital rights management (DRM), certification, control and security. As current solutions rely on proprietary architectures and tools, we propose an open architecture, as general as possible and not restricted to a specific standard, which provides trust and rights management in multimedia information systems. We analyse how the elements of the architecture provide trust to the whole value chain by managing multimedia content and digital rights represented using current standards, such as MPEG-21 and OMA DRM, and we compare it with an alternative approach. Then, we illustrate the system operation through a content composition use case, and finally, we present the software tools that we have already developed and the future work. © IFIP International Federation for Information Processing 2005.
