We propose a new watermarking method in the time domain

which utilizes a local set of information of each vertex to embed watermarking information and blind-detect. During the embedding process

appropriate vertices are selected to be embedded with the watermarking information according to local set area of each vertex on purpose of improving imperceptivity. As the detection progresses

the same local set area information is obtained to build the synchronization between embedding and detecting. This improves the robustness of the proposed. The property of affine invariant of first order moment makes the algorithm resisting attacks of rotation

translation

uniform scaling easily. The experiment has shown that

while the attacks are not so strong to damage the visual quality of 3D object

the algorithm acquires high robustness to resist attacks of adding noise and smooth-filtering.
