K. J. Ray Liu, University of Maryland
Every technology has its time: in the past decades, we have witnessed advances in communication and networking infrastructure, followed by the development of multimedia compression and coding standards, and then the demands of content search and retrieval. This path of technological evolution has naturally led to an unsolved critical issue, that is, information assurance and forensics. Multimedia forensics is to reconstruct what have happened to the content to answer who has done what, when and how. It is an emerging new filed seeing its horizon rising via the interdisciplinary interactions of signal processing, cryptology, communication and information theory, game theory, and the psychology of human visual/auditory perception.
In this talk, three exemplary multimedia forensic cases - namely traitor tracing forensics, behavior forensics, and non-intrusive component forensics, all posting different technical issues with different applications, will be illustrated with details to highlight the excitement of Sherlock Holmes when examining evidences for multimedia forensics via the tools of signal processing.
Dr. Liu is Professor and Associate Chair of Graduate Studies and Research, Electrical and Computer Engineering Department, University of Maryland, College Park. Dr. Liu leads the Maryland Signals and Information Group (SIG) with research contributions encompass broad aspects of information forensics and security; multimedia communications and signal processing; wireless communications and networking; biomedical imaging and bioinformatics; and signal processing algorithms and architectures, in which he has published over 400 refereed papers. He is a co-author of Multimedia Fingerprinting Forensics for Traitor Tracing, EURASIP Book Series on Signal Processing and Communication (Hindawi), 2005.
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, IEEE 50th Vehicular Technology Conference Best Paper Award in 1999, EURASIP Best Paper Award in 2004, IEEE Signal Processing Society 2004 Distinguished Lecturer, and EURASIP 2004 Meritorious Service Award. Dr. Liu is a Fellow of the IEEE. He also received the 2005 Poole and Kent Company Senior Faculty Teaching Award from A. James Clark School of Engineering, University of Maryland, as well as the George Corcoran Award in 1994 for outstanding contributions to electrical engineering education, and the Outstanding Systems Engineering Faculty Award in 1996 in recognition of outstanding contributions in interdisciplinary research from Institute for Systems Research. He also received the 2004 Invention of the Year Award from University of Maryland.
