Welcome to my home in cyberspace 

I joined the faculty of the Electrical & Computer Engineering Department (ECE) and the Institute of Advanced Computer Studies (UMIACS)  at the University of Maryland, College Park in Fall 2001, where I am currently an Associate Professor.  I am also affiliated with the Institute of Systems Research (ISR) at UMCP.

My research addresses issues related to security, forensics, processing, and communication of multimedia.  I hope that my research, joining those by other researchers in the field, can make the wonderful world of Multimedia reachable for more people.

Recent Activities

A recent book "Multimedia Fingerprinting Forensics for Traitor Tracing " in Fall 2005 (EURASIP Book Series, by Hindawi Publishing Co.)

A tutorial on "Digital Fingerprinting for Multimedia Forensics" given at ICASSP'05 conference on March 19, 2005 in Philadelphia;

Co-editor of Special Issue on Multimedia Security and Rights Management in EURASIP JASP Journal (published Oct. 2004)

Digital Fingerprinting Fingerprinting is a general way to combat unauthorized re-distribution of valuable data by putting a unique ID in the data to identify each recipient.  Several users may come together to erase the fingerprints.  We proposed a new anti-collusion fingerprinting that can trace illegal distributors and colluders, and studied a few related research issues such as the interplay between encoding and embedding of fingerprints. This activity is  sponsored in part by Air Force Research Laboratories and Office of Naval Research's Young Investigator Program.
My book,  "Multimedia Data Hiding", (co-authored with Prof. Bede Liu, Springer-Verlag, 2002), addresses both fundamental and practical issues, and tackles both design and attack problems. [Available at Amazon.com and Barnes&Nobles]
TR100 I was selected by MIT Technology Review Magazine in 2004 as one of the 100 top young innovators under age of 35 whose contribution to emerging technologies will profoundly influence our world, shaping how we live and work in the future. Also in 2004, Washingtonian Magazine named me as one of the “20 young people to watch” in the special issue on “The Best of the Washington”.

My research on "Signal Processing Approaches for Multimedia Security and Information Protection" is sponsored by NSF through a 5-year CAREER award program ('02-'07).  [E@M Magazine news]
