Abstract :

A new secure image transmission method is proposed, Here it uses the technique of Steganography and Cryptography, Which transforms automatically a given large-volume secret image into a so-called secret-fragment-visible mosaic image of the same size. The mosaic image which looks similar to an arbitrarily selected target image and may be used as a disguise of the secret image is yielded by dividing the secret image into fragments and transforming their color characteristics to be individuals of the corresponding blocks of the target image. Then applying encryption method and adding relevant information /key and get back the data with decrypting by the give key for improving security, Skillful techniques are designed to behavior the color transformation process so that the secret image may be recovered nearly lossless. A scheme of handling the overflows/underflows in the converted pixels' color values by recording the color differences in the untransformed color space is also proposed. The information required for recovering the secret image is embedded into the created mosaic image by a lossless data hiding scheme using a key. Good experimental results show the feasibility of the proposed method.
