Steganography pdf

Steganography is the technique of hiding confidential information within any
media. Steganography is often confused with cryptography because the two are
similar in the way that they both are used to protect confidential information. The
difference between the two is in the appearance in the processed output; the
output of steganography operation is not apparently visible but in cryptography
the output is scrambled so that it can draw attention. Steganlysis is process to
detect of presence of steganography. In this article we have tried to elucidate the
different approaches towards implementation of steganography using
‘multimedia’ file (text, static image, audio and video) and Network IP datagram
as cover. Also some methods of steganalysis will be discussed.
