Adobe researchers are developing two plug-ins for PhotoShop which could detect whether or not a photo has been retouched. Demand for photo-authentication tools is growing in response to the increase in news being spread via blogs and photo-sharing websites.

Adobe is collaborating with Professor Hani Farid, an expert in photo and image fraud detection, on the development of the products.

The Clone Tool Detector can identify if a section in a picture has been recopied from another part of the picture.

The second tool can identify if pixels are missing from a photo, which could indicate that an image has been cropped.

Adobe has not yet decided if the tools will be added to Photoshop. The company is currently beta testing a new version of Photoshop, CS3, that will be announced at the end of March.
