New software being developed can detect Photoshopped images using “ballistics” technology

If you have a good eye, it can be easy to spot an image that’s been Photoshopped. Of course, the best image alterations can be nigh undetectable, which can pose problems if you absolutely must know if the picture is genuine. This is why one Dartmouth scientist, Hany Farid, has been working on a piece of software that is the equivalent of gun ballistics for pictures.

First, the software analyzes the image and compares it to a database of the over 10,000 digital cameras that have been sold. If there are any variations in the signature, then it can tell you immediately that it has been doctored. The program can also specifically detect whether or not the image has been opened (and therefore, likely altered) in Photoshop. No, Photoshop is not the only software capable of manipulating pictures, but it is one of the most common. Farid is also working with Adobe to help develop this technology, but he’s not decided if he’ll partner with them when he decides to place the software on the market.

Yes, that does mean that this interesting bit of tech cannot currently be obtained. If you don’t mind using something a little less high-tech (but still extremely useful) you might might check out this site. It uses a different technique, but does seem to yield decent results.
