Wired News: Adobe Tackles Photo Forgeries

Wired News: Adobe Tackles Photo Forgeries:
"A suite of photo-authentication tools under development by Adobe Systems could make it possible to match a digital photo to the camera that shot it, and to detect some improper manipulation of images, Wired News has learned.

Adobe plans to start rolling out the technology in a number of photo-authentication plug-ins for its Photoshop product beginning as early as 2008. The company is working with a leading digital forgery specialist at Dartmouth College, who met with the Associated Press last month. ..."

This should have a clear effect on the use of images, which are powerful adjuncts to news stories (and propaganda). Photoshop has been a highly useful tool in dealing with digital photos, but it can be turned to dishonest ends just as easily.

This work is based on the research of Dr Hany Farid who has written a short (5 page) explanation of how forgeries can be detected, using as examples several recent manipulated images, including one particularly blatant one from Lebanon that was reported first on a blog, and then by the Washington Post.
