coondoggie writes: It isn't hard for just about anyone to change or alter an image these days — and that can be a problem. It's an issue researchers at the Defense Advanced Research Projects Agency want to put to rest with a new program called Media Forensics, or MediFor, which looks to build an algorithmic-based platform that can detect image manipulation. "The forensic tools used today lack robustness and scalability and address only some aspects of media authentication; an end-to-end platform to perform a complete and automated forensic analysis does not exist. Although there are a few applications for image manipulation detection in the commercial sector, they are typically limited to a yes/no decision about the source being an "original" asset, obtained directly from an imaging device. As a result, media authentication is typically performed manually using a variety of ad hoc methods that are often more art than science, and forensics analysts rely heavily on their own background and experience," DARPA states.
