Robust digital watermarking is an evolving research area that has received a large amount of attention and became a practical solution to copyright protection. This paper proposes a robust and imperceptible non-blind watermarking method for high rate embedding into 3D polygonal meshes. Our approach consists of vertices selection, embedding and extracting steps. First, the vertices are selected for embedding if they are greater than defined threshold, and then the watermark bits are embedded

The experimental results showed that the proposed algorithm provides high robustness against the most common attacks. The applied attacks include connectivity attacks such as mesh smoothing, and mesh cropping and the geometric attacks such as rotations, uniform scaling and their combinations.
