Abstract
This paper provides a technique for the protection of image in open wireless channel. It depends on steganography and cryptography (double random phase encoding). In this method primary step is to cover a message image inside an another image through steganography to make a stego image and then a simple encoding technique; double random phase encoding (DRPE) is perform on stego image. For the evaluation of proposed technique, statistical tests like entropy, time analysis and peak to signal noise ratio (PSNR) with and without noises (Gaussian, salt n pepper and speckle) are performed which illustrate that the proposed technique provide better security to the transmitted image in wireless channel than the other techniques.
