Provided by: International Journal of Computer Science and Information Technologies Topic: Security Date Added: Mar 2012 Format: PDF
Steganography, literally meaning "Secret writing", involves hiding a data file in another innocuous-looking file. From the time of Herodotus in Greece, to the defense mechanisms of today, steganography has been used to deny one's adversaries the knowledge of message traffic. Steganography takes one piece of information and hides it within another. A "Container file" holds the secret message in it, in such a way that the existence of the message cannot be suspected. This could be done in several possible ways, with newer methods being discovered with each passing day.
