| Abstract: |
This paper proposes a technique for reversible information hiding using the complexity measure defined to binary images. By the complexity measure, we can classify blocks on bit-planes of cover images into three groups: L (Left) group, R (Right) group and M (Middle) group. By assigning a 0 to L and a 1 to R, and then scanning all blocks of the image, the status of the image is obtained. Not only the additional information but also the compressed bit sequence is embedded to recover the original one. We can embed one message bit in each L and R group. To obtain a match of a bit from the information to be embedded and the group type of blocks, we apply the logical operation called conjugate operation which is able to flip each group and completely recover original one. The original cover images can be recovered by applying the conjugate operation to the blocks group type has been changed. |
