Abstract
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. The image are partitioned in the ten level block, and the text data will be embedded into ten diagonal or linear sub block values which is depend upon key. The quality of produced image is better using the median filter while using this algorithm.
