Abstract

One of the great challenges of the existing watermarking methods is their limited resistance to the extensive geometric attacks. Geometric attacks can be decomposed into two classes: global distortion such as rotations and translations and local distortion such as the StirMark attack. We have found that the weakness of multiple watermark embedding methods that were initially designed to resist geometric attacks is the inability to withstand the combination of geometric attacks. In this paper, the watermark is used in the gray-scale authentication image. We propose a robust image watermarking scheme that can withstand the geometric attacks by using local tri-mesh feature points. Our proposed method can resynchronize the attacked images and is independent of the embedding and authentication process. The geometric invariant scheme is combined with the complementary modulation embedding strategy to enhance the resistance of geometric attacks. The experimental results verify that the proposed scheme is effective for geometric attacks.
