Watermarking scheme for copyright protection of 3d animated model

This paper presents 3D geometric watermarking scheme for general 3D animation model, which it has most of the hierarchical structure with various transform nodes of geometry and interpolator. The proposed scheme selects some transform nodes with geometric property and embeds the watermark into the distance distribution of vertex coordinates in the selected transform node. Experimental results verified that the proposed scheme has the robustness against most of modifiers in public 3D editing tool as well as the invisibility.
