New Software Tells You If Photo Is A Photoshop Fake

In the age of Photoshop, it’s almost impossible to say with absolute certainty whether any given image is real, but one former Photoshop employee hopes to change that.

Fourandsix Technologies, a startup founded by a former Adobe Photoshop executive and a digital forensics expert, unveiled its first piece of software this week, which promises to help law enforcement determine whether a photo is authentic or not.

The software, called FourMatch, analyzes the meta data in picture files to quickly determine if a photo has been modified. FourMatch relies on a comprehensive database of more than 70,000 “signatures” that are left on a file from each piece of hardware and software that goes into creating it. As the company explains in a description of the product, “Once an image has been edited and resaved from a software product, this signature is changed to match the software rather than the original capture device.”

FourMatch is primarily intended for police and lawyers who need to determine whether a photograph has been tampered with in any way between the time it was first captured and submitted as evidence. However, the software won’t tell you exactly how the image has been altered — if it has been at all — because it only analyzes the file data rather than the image itself. For this reason, it can just tell you if a file has been touched by another application.
