About the technology author(s):
Ching-Yung Lin joined IBM T. J. Watson Research Center as a research staff member in October 2000. He received his B.S. and M.S. from National Taiwan University, in 1991 and 1993,
respectively, both in Electrical Engineering. He received his Ph.D. in the Department of Electrical Engineering, Columbia University, in 2000. Dr. Lin was a wireless officer at R.O.C. Air Force, Taiwan, from 1993 to 1995 and an instructor of Network Communication Lab at National Taiwan University from 1995 to 1996. His current research interests include multimedia authentication and watermarking techniques for security; multimedia semantic analysis; indexing and query; multimedia transmission and networking; Human-Computer Interaction; and multi-rate, multidimensional signal processing. Dr. Lin was the primary contributor in the design of the first successful semi-fragile content authentication system (SARI), which distinguishes JPEG/MPEG compression from malicious manipulation; he was also the primary contributor in the design of the first public/oblivious watermarking methods surviving the print-and-scan process.
Belle L. Tseng joined IBM T. J. Watson Research Center in 1997. She received her Ph.D. in Electrical Engineering from Columbia University in 1996 and her M.S. and B.S. in Electrical
Engineering and Mathematics from MIT in 1992. Her research interests include 3-D stereoscopic systems; MPEG video CODECs; multi-viewpoint, 3-D TV applications; and 3-D interactive devices. Dr. Tseng is currently working on multimedia database, semantic understanding, personalization, and summarization projects at the Pervasive Multimedia Management department. Her major contributions include the MPEG-2 stereoscopic CODEC, immersive whiteboard collaboration system, rich media summarization, and personalized content adaptation.
John R. Smith is manager of the Pervasive Media Management Group at IBM T. J. Watson Research Center, where he leads a research team exploring techniques for multimedia content management. He is currently Chair of the MPEG Multimedia Description Schemes (MDS) group and serves as co-Project Editor for MPEG-7 Multimedia Description Schemes. Dr. Smith received his M. Phil and Ph.D. degrees in Electrical Engineering from Columbia University in 1994 and 1997, respectively. His research interests include multimedia databases, multimedia content analysis, compression, indexing, and retrieval. Dr. Smith is an adjunct professor at Columbia University and a member of the Institute of Electrical and Electronics Engineers (IEEE).
