The technique of hiding confidential information within any media is known as Stegonography. Since both stegonography and cryptography are used to protect confidential information, the two are used interchangeably. This is wrong because the appearance of the output from the two processes is totally different; the output from a stegonography operation is not apparently visible while for cryptography the output is scrambled such that it easily draws attention. The detection of the presence of stegonography is referred to as Steganlysis. In this article we have attempted to elucidate the main image steganography approaches, and then we will evaluate the techniques and result will show in a table and discuss.
