abstract: |
In this paper, a scheme that has tamper proofing and recovery abilities is proposed. With the specific DCT frequency coefficients taken as the characteristic values, which are embedded into the least significant bits of the image pixels, it is used to provide proof of image integrity. If the image is tampered, the embedded characteristic values that are affected will be changed accordingly and then detected. Then the corresponding original characteristic values can be acquired by the proposed recovery process to reconstruct the image. |
