Digital Image Forensics

Project Summary: It is probably fair to say that it is no longer true that seeing is believing. The ease with which digital media can and is being manipulated and altered is simply stunning. At least one consequence of this is that images and video recordings no longer hold the unique stature as a definitive recording of events. And, while the technology to alter digital media is developing at break-neck speeds, the technology to contend with the ramifications is lagging seriously behind. There is, therefore, a critical need to develop tools to detect tampering in digital media. To this end, we have been developing statistical tools for detecting tampering in digital images.
