Image Steganography is to hide messages or information within other information in such a way as to not be detectable. This makes use of the fact that there is a large amount of data being transferred every second, making it impossible to scan all the information for hidden messages. Typical cryptographic methods obscure the information, but it is still very obvious that a message is being sent. Steganography attempts to correct this flaw so an observer is unable to know if a message is being sent or not. This can be used in addition to traditional cryptographic methods, so the security will only be enhanced, assuming that the traditional methods are being used with the same rigor as before.
