Recently there has been much research in reversibly data hiding in already encrypted images. The data hiding scheme allows one to hide data in the image that has been encrypted with a stream cipher, without having the prior knowledge of the image content. The reversibility is achieved using strong correlation of the neighbouring pixels with each other. In this paper we propose a data hiding method in encrypted images that is not reversible but the directly decrypted image has acceptable psnr.
