Broad Area Colloquium For AI-Geometry-Graphics-Robotics-Vision
Digital Image Forensics
October 16, 2006, 4:15PM
With the advent of high-resolution digital cameras, powerful personal
computers and sophisticated photo-editing software, the manipulation
of digital images is becoming more common. We are seeing the impact
of these technologies in nearly every corner of our lives. While the
technology that allows for digital media to be manipulated and
distorted is developing at break-neck speeds, our understanding of the
technological, ethical, and legal implications is lagging behind. I
will discuss some of these issues and describe computational
techniques which we have developed for detecting tampering in digital
media. Operating in the absence of digital watermarks or signatures,
these techniques quantify and detect statistical correlations that
result from specific forms of digital tampering.
About the Speaker
Hany Farid received his undergraduate degree in Computer Science and Applied Mathematics from the University of Rochester in 1989. He received his Ph.D. in Computer Science from the University of Pennsylvania in 1997. Following a two year post-doctoral position in Brain and Cognitive Sciences at MIT, he joined the Dartmouth faculty in 1999. Hany's primary appointment is in the Computer Science Department where he is an Associate Professor and Associate Chair. He also holds a joint appointment in the Center for Cognitive Neuroscience. Hany is the recipient of an NSF CAREER award, a Sloan Fellowship and a Guggenheim Fellowship.
From working with federal law enforcement agencies on digital forensics, to the digital reconstruction of Ancient Egyptian tombs, Hany works and plays with digital media at the crossroads of computer science, engineering, mathematics, optics, and psychology.
