data leakage

The unauthorized transfer of classified information from a computer or datacenter to the outside world. Data leakage can be accomplished by simply mentally remembering what was seen, by physical removal of tapes, disks and reports or by subtle means such as data hiding (see steganography).



steganography

Hiding a message within an image, audio or video file. Used as an alternate to encryption, it takes advantage of unused bits within the file structure or bits that are mostly undetectable if altered. A steganographic message rides secretly to its destination, unlike encrypted messages, which although undecipherable without the decryption key, can be identified as encrypted. For a white paper on the subject written by Neil F. Johnson of George Mason University, visit www.jjtc.com/Steganography. See ScramDisk and social steganography.
