Abstract

This paper presents a novel watermarking scheme for 3D keyframe animation based on geometric structure and interpolator. The geometric watermarking embeds the watermark into the distribution of vertex coordinates in each of initial mesh models. The interpolator watermarking embeds the same watermark into key values in position interpolator. Experimental results show that the proposed scheme has the robustness against various geometric attacks and timeline attacks as well as the invisibility.
