Abstract:

In the last few years we have witnessed a paradigm shift in the design of Digital Rights Managemet (DRM) schemes. The first DRM schemes were characterized by the desire to limit unauthorized re-distribution of content as much as posible by restricting the actions a user can perform on DRM-enabled devices. As this forced users to change their viewing habits, early DRM schemes suffered from limited consumer acceptance. To overcome these problems, alternative DRM architectures, which focus on deterrence rather than prevention, are increasingly gaining attention from the research community: Instead of preventing every potentially infringing operation, they deter large-scale infringements by monitoring viewer habits and providing tracing facilities for content owners. This talk gives an overview of technologies required and research challenges encountered when designing 'consumer-friendly' DRM architectures.

Dr. Stefan Katzenbeisser was born in Austria in 1978, and obtained his Ph.D. degree from the Vienna University of Technology. After working as a research scientist at the Technical University in Munich, he joined Philips Research in 2006. His current research interests include Digital Rights Management, security aspects of digital watermarking technology and cryptographic protocol design.

He has authored over 30 scientific publications and served in the program committees of several workshops and conferences devoted to watermarking and applied cryptography. Among others, he was the program chair of the Information Hiding Workshop (2005) and the International Workshop on Digital Watermarking (2007). Currently he is an associate editor of the EURASIP Journal on Information Security.
