A location map-free visible and reversible watermarking method with authentication ability

This paper proposes a visible and reversible watermarking method. The proposed method visibly marks an image once, and it recovers the original image from the marked image. To recover the original image, this method never requires any location map in which watermarked positions are indicated. In addition, the proposed method is capable to detect image tampering. Simulation results show the effectiveness of the proposed method.
