Cryptography is the science and art of encrypting and decrypting text data where steganography is the science and art of hiding information. Steganography deals with composing hidden message so that only the sender and receiver know that the message even exists. A novel approach i.e. CryptSteg is introduced where sender embedding text message in the picture and send it to the receiver. In this approach the algorithm of cryptography and Steganography is combined. Firstly, the text message is encrypted and this encrypted message is then embedded in an image using a new steganography algorithm.
