For example, a message might be hiddenwithin an image by changing the least significant bits tobe the message bits.
[Chaffing and Winnowing: Confidentiality without Encryption, Ronald L. Rivest, MIT Lab for Computer Science, 1998-03-22].steganographyHiding 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.
