题目： Digital Forensics: General Concepts and Some New Results

报告人：Dr. Yun Q. Shi, IEEE Fellow

Professor, New Jersey Institute of Technology, USA

时间： 2009年3月18日 (周三)， 下午4.10

地点：东校区教学楼 B－103

Abstract:

In the first part of this talk, the concept of digital forensics is discussed. Some current research subjects in the field of forensics, including image tampering detection, computer graphics classification, and camera identification are introduced. The urgent needs for forensics are justified by demonstrating that the data hiding, cryptography, and combination of both have been shown not sufficient in many applications. In the second part of the talk, two different approaches to forensics are discussed. One is more on specific side, another is more on universal side. Some new research results in forensics are presented. One is on camera brand and model identification, another is on computer graphics classification from photographic images.

题目： Fast and Robust Video Copy Detection Techniques

报告人：DDr. C.-C. Jay Kuo, IEEE Fellow

Abstract:

The rapid development of digital video processing technologies and the increasing bandwidth enable easy access, editing, and distribution of digital video contents. Copyright protection becomes a growing concern for content creators/owners nowadays. One of the key problems is duplicate video detection. For example, there are many illegal video copies upload to the YouTube website every day. It is important for YouTube to identify these illegal copies fast. In this work, we propose a novel video detection system that can identify duplicate video copies very efficiently. We propose a compact signature based on the underlying video structure, which is discriminative yet insensitive to various attacks. In addition, we propose to use an extremely efficient matching technique, which is originated from fast symbol string search. Unlike images and audio, the size of videos is usually very large, which makes it computationally expensive to match two very long video sequences. Our system can perform the matching in linear time while the computational cost usually grows at least quadratically as the length of the video for other existing solutions.

Dr. C.-C. Jay Kuo received the Ph.D. degrees from the Massachusetts Institute of Technology in 1987. He is now with the University of Southern California (USC) as Director of Signal and Image Processing Institute and Professor of EE, CS and Mathematics. His research interests are in the areas of digital media processing, multimedia compression, communication and networking technologies, and embedded multimedia system design. Dr. Kuo is a Fellow of IEEE and SPIE. Dr. Kuo has guided about 90 students to their Ph.D. degrees and supervised 20 postdoctoral research fellows. Currently, his research group at USC consists of around 35 Ph.D. students (see website http://viola.usc.edu), which is one of the largest academic research groups in multimedia technologies. He is a co-author of about 150 journal papers, 770 conference papers and 9 books. Dr. Kuo is Editor-in-Chief for the Journal of Visual Communication and Image Representation, and Editor for the Journal of Information Science and Engineering, LNCS Transactions on Data Hiding and Multimedia Security (a Springer journal), the Journal of Advances in Multimedia (a Hindawi journal) and the EURASIP Journal of Applied Signal Processing (a Hindawi journal). He was on the Editorial Board of the IEEE Signal Processing Magazine in 2003-2004. He served as Associate Editor for IEEE Transactions on Image Processing in 1995-98, IEEE Transactions on Circuits and Systems for Video Technology in 1995-1997 and IEEE Transactions on Speech and Audio Processing in 2001-2003.
