3-D Model Asymmetric Watermarking Algorithm Based on Optimization Square Error

A novel method suitable for 3D mesh objects watermarking applications are proposed.Through choosing the vertexes,we lead to the embedded watermark that has the least modified to topology transform of the 3D geometry model,and then,project the watermark to the space that has the least mean square error value.So,we obtain that the robustness of the approach lies in hiding a watermark in the space that is least susceptible to 3D model geometrical modification.The robustness of our method is demonstrated by attacks through simulation.
