The information security has become essential part of today’s world due to extensive use of internet. The privacy of secret data can be achieved with two classical methods of data security namely Cryptography and Steganography.Cryptography results in scrambling of data into cipher text which is in unreadable or in nonexplainatory form, difficult to be guessed by eavesdropper, Steganography on the other hand hides the secret data into carrier medium in such a way that its detection is prevented.Steganography is not a replacement of cryptography but can supplement it to produce good results. It is observed that steganography alone is not sufficient for information security, so we can make more secure and robust approach by combining the best of steganography and cryptography. This paper describes the various steganographic techniques combined with cryptography.
