Encrypt Information In Images Without Distortion

Nomikos writes "C|Net reports: Researchers have created a new way to encrypt information in a digital image and extract it later without any distortion or loss of information. A team of scientists from Xerox and the University of Rochester said that the technique, called reversible data hiding, could be used in situations that require proof that an image has not been altered."

People have been doing this for some time. You simply print out the data. Take a photo of it. Scanthe photo. Send the photo. No distortion of the image with the data on it.

The RIAA and MPAA have sponsored new legislation to make images illegal on the internet in the United States. Images have been known to carry illegal circumvention devices such as DECSS. Thus images in themselves are also potential circumvention devices under the DMCA.

Do not attempt to reverse engineer or theorize about this encryption. They say it's encrypted, that's enough for you.
