Cyber warfare: steganography vs. steganalysis

Check this out, it is a very cool technique for hiding data in data, for copyright proctection, spying, et al. A UMM grad at Carnige Mellon U was working on steganography for his disseration. I've only had brief conversations about it, but it is some cool stuff.

Check out the article:
ACM Queue - Cyber warfare: steganography vs. steganalysis - For every clever method and tool being developed to hide information in multimedia data, an equal number of clever methods and tools are being developed to detect and reveal its secrets.: "The rise of the Internet and multimedia techniques in the mid-1990s has prompted increasing interest in hiding data in digital media. Early research concentrated on watermarking to protect copyrighted multimedia products (such as images, audio, video, and text) [1, 8]. Data embedding has also been found to be useful in covert communication, or steganography. The goal was and still is to convey messages under cover, concealing the very existence of information exchange."
