Non-invertible Watermarking Scheme for 3D Meshes
不可逆的3维网格模型数字水印算法

This paper presents a novel watermarking scheme based on singular value decomposition(SVD) for 3D meshes, it embeds the watermark into the singular values which equal zero. This watermarking scheme is non-invertible, since the singular value is zero. This algorithm can quickly embed the watermark to large-scale 3D meshes and is robust to various attacks. Finally we analyze some necessary conditions to construct the non-invertible scheme.
