A novel and improved method for joint reversible data-hiding and compression scheme for digital multiband images is proposed in this paper. The image compression techniques like vector quantization and side match vector quantization along with the image inpainting are used for data hiding and compression. In the proposed method, from the multiband image the user can select the bands to hide the secret data according to the size and nature of the data to be embedded. On the sender side, the bands are sub divided into equal size blocks and the number of blocks determines the hiding capacity.
