In this paper, we present a watermarking technique for authentication of 3-D polygonal meshes. The proposed technique is based on a wavelet-based multiresolution analysis to convert an original polygonal mesh model into a simplified mesh model and wavelet coefficient vectors. The embedding procedure is to modify the vertex of a simplified mesh model at a low resolution according to the order of norms of the wavelet coefficient vectors using a look-up table. The watermark extraction process is to restore the binary logo pattern by extracting a binary watermark bit from a look-up table corresponding to the watermarked simple mesh. The experimental results show that the proposed method is invariant to the location, scale and rotation transformation while detecting unauthorized modifications. © Springer-Verlag Berlin Heidelberg 2005.
