Does My Eye Deceive Me? Not With These Digital Forensics Tools

The Internet is awash with images and videos that may hold national security and intelligence value, but the task of teasing out real images from  altered ones is formidable. Even off-the-shelf editing tools can trick digital forensics experts. Nasir Memon, professor of computer science and engineering at the New York University Tandon School of Engineering, has joined with two teams of faculty from universities around the world to design the ultimate digital forensics tools — technologies so advanced they’ll be able to catch the subtlest manipulations of still images and video, discerning not only whether media has been tampered with, but precisely how.
