The technique of data hiding reversibly in encrypted images may be considered as an efficient method that can be used to hide data within an image that is being encrypted. In prevailing methods of data hiding, as in any other encryption standards, an image that has to be transmitted is encrypted first. This encryption is done by the sender by using any encryption key that is unknown to anyone accessing the image. It can be possible to introduce or cover information within the image that has been encrypted. This can be done without knowing any information about the image or about its encryption. On the receiver side, a recipient can decode the image if he has the encryption key or can retrieve the hidden message if he has the data hiding key. The methods must be able to perform a high payload compensating a high quality of image that has been reconstructed. Here various techniques that use reversible data hiding are reviewed in this paper and this leads to bitwise prediction data hiding. |
