A robust and invisible watermarking of 3D triangle meshes

Abstract

With the rapid development of computer multimedia, how to protect digital products from being copied, pirated and juggled has been an urgent issue in the information security field. Digital watermarking is a new method to solve the referred problems. This paper proposes a digital watermarking algorithm for three-dimension (3D) mesh models. The watermark is embedded into the host with modifying the lengths between the vertices and the centroid of models. The embedded watermark is invisible and can withstand the common attacks such as polygon mesh simplifications, addition of random noise, and similarity transforms. The validity of proposed algorithm has been confirmed with experiments. © Springer-Verlag Berlin Heidelberg 2005.
