FourMatch can tell you if an image has been photoshoppedIvan | Fri, 2012-09-21 21:46
Fourmatch is a rather expensive ($890) plug-in for Adobe Photoshop CS5 which allows you to authenticate images and see if they are original or not. Watch the video to see how the app does it.
I wonder how easy it is to reverse engineer this app and forge all the required signatures on a fake photo in order to get a false positive result.
