It is important to represent MPEG-4 BIFS with LASeR format to service the existing MPEG-4 scene in mobile environments. 2D and 3D graphics are represented by MPEG-4 BIFS but LASeR supports only 2D nodes. Because it is difficult to represent the 3D geometry nodes of BIFS with LASeR, converting process is needed. In this paper, watermarking scheme of 3D object based on MPEG-4 LASeR is proposed. Watermarks are embedded while MPEG-4 BIFS 3D geometry nodes are converted into LASeR 2D graphic nodes. Proposed watermarking algorithm uses vector information of polygon and original model is needed in extraction procedure. This proposed watermarking algorithm has good imperceptibility and robustness against the geometrical attacks such as noise addition, smoothing, mesh simplification and compression. And it is proved that this proposed algorithm is good for integrity authentication by the experiment.
