Currently considered unbreakable, a code encryption technique called "steganography" is used to bury a message in a digital image, audio, or video file. The sender uses a unique key to encode the file and then posts it somewhere on the Internet (e-Bay, discussion group, etc.). The receiver visits the site, downloads the file and uses a matching key to decode the message. The boys at NSA aren't too happy about this one.
