Terrist messages in digital photographs questioned (salon.com). Last week, USA Today raised a stir by claiming that terrorists were trading hidden messages in images on ebay by the "hundreds" using an uncited source. Salon contacting other sources willing to go on the record found that finding hundreds of hidden messages requires sampling more files than were posted to ebay in the past year. In addition steganography analysis turns up a high rate of false-positivies. Is this a case of seeing what we want to see like the Bacon-Shakespeare ciphers?
A University of Michigan study has concluded that terrorists were not using hidden messages embedded in eBay auction images to plan the attacks. However, speculation that Ritz cracker advertisements were used has not yet been refuted.
