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. Its uses could range from sensitive military and medical diagnostic images to legal documents and photographs of crime scenes. The technique could also be used to encode information within the image itself for cataloging and retrieving from databases. The link for this article located at ZDNet is no longer available. .

Antivirus companies warned on Thursday of a new virus that communicates through digital images, but security experts aren't sure how much of a threat this latest evolutionary branch of malicious code poses. Dubbed the first "JPEG infector" by security company Network Associates, the W32/Perrun virus has two parts: infected JPEG images that contain the virus's payload and a viral program that extracts the code from the images and infects other JPEGs on the system as they are opened. Because PCs have to be infected by the extractor virus before any code hidden in image files can affect them, the program is more a computer-science curiosity than a threat, said Vincent Gullotto, vice president of Network Associates' antivirus emergency response team.
