Technology advancement has made multimedia content widely available and easy to process. These benefits also make it easy for unauthorized duplication, manipulation, and redistribution of multimedia content, prompting the need of multimedia forensics research to facilitate evidence gathering in digital world. Digital fingerprinting is one of the emerging forensics technologies to help identify users who have legitimate access to content but may use it for unintended purposes, such as unauthorized redistribution. Unique imperceptible labels, known as digital fingerprints, are inserted in different copies of the same content before giving to each user. For multimedia data, digital fingerprints can be put into the content using conventional robust embedding techniques, which are typically concerned with surviving attacks mounted by an individual. Advances in communication and networking have also made it easy for adversaries to work together. A group of users with differently marked versions of the same content may collaborate to collectively mount attacks against the fingerprints. These so-called collusion attacks provide adversaries with a cost-effective method to remove the fingerprints and circumvent the traitor-tracing mechanism.
In this talk, I will present our recent research on anti-collusion fingerprinting for multimedia data. Through jointly considering the encoding, embedding, and detection of fingerprints, our techniques can help collect digital-domain evidence and pinpoint to the sources of leak among millions of users. Applications of such multimedia forensic tools range from military and government operations to piracy deterrence in Hollywood and other entertainment industry.Biography:
Dr. Min Wu received the B.E. degree in electrical engineering and the B.A. degree in economics in 1996 from Tsinghua University in Beijing, China (both with the highest honors), and the Ph.D. degree in electrical engineering from Princeton University in 2001. Since 2001, she has been on the faculty of Department of Electrical and Computer Engineering and Institute of Advanced Computing Studies at University of Maryland, College Park, where she is currently an Associate Professor. Dr. Wu's research interests include information forensics and security, multimedia signal processing, and multimedia communications. She co-authored two books and holds five U.S. patents on multimedia security and communications. She is a co-recipient of two Best Paper Awards from the IEEE Signal Processing Society and EURASIP, respectively. She also received a U.S. National Science Foundation CAREER award in 2002, a TR100 Young Innovator Award from the MIT Technology Review Magazine in 2004, and a U.S. ONR Young Investigator Award in 2005.
