Abstract: The recent growth of networked multimedia systems has demanded the need for better protection of the digital rights of multimedia. Traditional protection alone, such as encryption and authentication, is no longer sufficient after the content is delivered to an authorized user. To address such an information assurance issue, a new field of information forensics is emerging to conduct forensic modeling and analysis to reconstruct events: Who have done what, when, where, and how?

Due to the global nature of Internet, ensuring the appropriate use of media content, however, is no longer a traditional security issue with a single threat or adversary. Rather, new threats are posed by coalitions of users who can combine their contents to undermine the fingerprints. Such multi-user attacks, known as collusion attacks, provide a cost-effective method for removing an identifying fingerprint, and thus pose a strong threat to protecting the digital rights of multimedia. To mitigate the serious threat posed by collusion, theories and algorithms are being investigated and developed for constructing forensic fingerprints that can resist collusion, identify colluders, and corroborate their guilt. Therefore multimedia forensics has become an emerging field built upon the synergies between signal processing, cryptology, coding theory, communication theory, information theory, game theory, and the psychology of human behavior and social networks.

This talk will provide audience with a broad overview of the recent advances in multimedia forensics with a focus on traitor tracing forensics, behavior forensics, and non-intrusive component forensics, all posting different technical issues with different applications to highlight the excitement of Sherlock Holmes when examining evidences for multimedia forensics via the tools of signal processing.

About the Distinguished Scholar-Teacher program:

The Distinguished Scholar-Teacher program recognizes faculty members who have demonstrated outstanding scholarly achievement along with equally outstanding accomplishments as teachers. Liu is one of six Maryland professors to receive the honor this year. Nominees for the award are selected by their peers; the six winners are chosen by a panel of former Distinguished Scholar-Teachers. Winners receive a cash award to support instructional and scholarly activities, and make a public presentation in the fall semester on a topic of scholarly interest.

Biography:

Dr. Liu received the B.S. degree from the National Taiwan University in 1983, and the Ph.D. degree from UCLA in 1990, both in electrical engineering. He is Professor and Associate Chair of Graduate Studies and Research of Electrical and Computer Engineering Department, University of Maryland, College Park. Dr. Liu is Director of Communications and Signal Processing Laboratories and leads the Maryland Signals and Information Group (SIG) with research contributions that encompass broad aspects of wireless communications and networking; multimedia communications and signal processing; information forensics and security; biomedical imaging and bioinformatics; and signal processing algorithms and architectures, in which he has published over 450 refereed papers, books, and book chapters.

Dr. Liu is the recipient of numerous honors and awards including the National Science Foundation 1993 Research Initiation Award (RIA) and 1994 National Young Investigator (NYI) Award, the IEEE Signal Processing Society Best Paper Award in 1993 and 2005, EURASIP Best Paper Award in 2004, IEEE 50th Vehicular Technology Conference Best Paper Award in 1999, IEEE Signal Processing Society 2004 Distinguished Lecturer, and EURASIP 2004 Meritorious Service Award. Dr. Liu is a Fellow of the IEEE.

He also received various research and teaching recognitions from the University of Maryland, including the 2007-08 Distinguished Scholar-Teacher Award from Office of the Provost, election as Fellow of Academy for Excellence in Teaching and Learning in 2007, 2005 Poole and Kent Company Senior Faculty Teaching Award from A. James Clark School of Engineering, 2004 Invention of the Year Award from Office of Technology Commercialization, as well as the George Corcoran Award in 1994 for outstanding contributions to electrical engineering education from Electrical and Computer Engineering Department, and the Outstanding Systems Engineering Faculty Award in 1996 in recognition of outstanding contributions in interdisciplinary research from Institute for Systems Research.

Dr. Liu was the Editor-in-Chief of IEEE Signal Processing Magazine, the founding Editor-in-Chief of EURASIP Journal on Applied Signal Processing, and the prime architect and proposer of IEEE Trans. on Information Forensics and Security and IEEE Journal on Selected Topics of Signal Processing. He has been an Associate Editor of IEEE Transactions on Signal Processing and has been a Guest Editor of special issues on Multimedia Signal Processing of Proceedings of the IEEE, special issue on Signal Processing for Wireless Communications of IEEE Journal of Selected Areas in Communications, special issue on Multimedia Communications over Networks of IEEE Signal Processing Magazine, special issue on Multimedia over IP of IEEE Trans. on Multimedia, and special issue on cooperative communications and networking of IEEE Journal of Selected Areas in Communications.

Dr. Liu is Vice President-Publications and on the Board of Governor of IEEE Signal Processing Society. He has served as the General Chair of IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP), Hawaii, 2007, the Chair of Multimedia Signal Processing Technical Committee, Technical Program Chair of IEEE International Conference on Multimedia and Expo, a panelist for various events of National Science Foundation, DARPA, and international conferences, and various capacities in organizing international conferences and workshops.

He is a co-author of Resource Allocation for Wireless Networks: Basics, Techniques, and Applications, Cambridge University Press, 2007; Network-Aware Security for Group Communications, Springer, 2007; Ultra-Wideband Communication Systems: The Multiband OFDM Approach, Wiley, 2007; Cooperative Communications and Networking, Cambridge University Press, 2008; Multimedia Fingerprinting Forensics for Traitor Tracing, EURASIP Book Series on Signal Processing and Communication (Hindawi), 2005; Design of Digital Video Coding Systems: A Complete Compressed Domain Approach, Marcel Dekker, 2001; and a co-editor of High Performance VLSI Signal Processing: Volume I: System Design and Methodology; Vol. II: Algorithms, Architectures, and Applications, IEEE Press, 1998.
