Stegnography is the most common term used in the IT industry, which specifically means, \"Covered writing\" and is derived from the Greek language. Stegnography is defined as the art and science of invisible communication i.e. it hides the existence of the communication between the sender and the receiver. In distinction to cryptography, where the opponent is permitted to detect, interrupt and alter messages without being able to breach definite security grounds guaranteed by the cryptosystem, the prime objective of stegnography is to conceal messages inside other risk-free messages in a manner that does not agree to any enemy to even sense that there is any second message present.
