Abstract
The image authentication with watermark and localization has been widely studied for many years. However, there are few of them providing the recovery in tampered region. In this paper, we proposed an authentication system not only providing localization as well as tampered region recovery. First, we construct a reference block from adjacent block. Then a residual block is provided by subtracting reference from original block. In our assumption, the energy of it is very low and convenient for us to embed. After encoded and embedded, a system with localization and recovery is constructed. From the simulations and experiments, we find that our proposed method gives a good vision quality. The localization of the tampered area is also successfully marked out and recovered with acceptable fidelity. Furthermore, the robustness of JPEG compression is also provided.
