Future Photoshop versions to detect phony images?


— 1:17 AM on March 9, 2007

Adobe is considering the addition of plug-ins that can detect doctored or forged images to its popular Photoshop image editing software, according to a report by CNet. The site says the company's Advanced Technology lab already has two plug-ins that are in a "fairly advanced stage of development." The plug-ins are described as follows:

One tool from Adobe, called Clone Tool Detector, determines whether a section in a picture, such as a patch of sand or a field of grass, has been recopied from another part of the picture. Last year, Reuters admitted that a photographer cloned a smoke plume in a shot of wartime Beirut. The tool can't ascertain with absolute certainty whether two items, say a pair of clouds or other images, have been cloned, but it will say that the two images are "improbably similar."

The other tool, informally known in the lab as Truth Dots, determines whether pixels are missing from a photo, a sign that the image has been cropped. Even if the images were greatly magnified, the human eye could not detect these.

An Adobe representative told CNet that the company has not yet made a decision regarding whether or not to add these plug-ins to the next version of Photoshop. However, Photoshop CS3 is currently being beta tested, and Adobe expects to launch it at the end of this month and to have it out in stores before the summer.
