In today's digital world the ways communication are getting better day by day which in turn giving rise to one major problem which is the security of the data transmission, for protecting the secret information from the intruder the existence of the data should be hidden from others for increasing the security we can also make the secret data unreadable which can be done by using various steganographic techniques along with the cryptographic techniques. Steganography hides the existence of the information whereas cryptography makes the data unreadable making the communication robust.
