Abstract (in Japanese) (See Japanese page) 
(in English) It is reported that a numerically stable digital watermarking for 3D model authentication. In the 3D watermarking for protecting falsification, they have proposed some watermarking methods that slightly perturb the positions of subset of vertices. However, these schemes have some numerical and safe problems. For example, one using floating-point arithmetic was pointed out that there are some cases it is not able to authenticate correctly for numerical reason. The other that use integer arithmetic can be easily altered and embedding watermark data are small amount. We focused our attention on developing a new watermark method for resolving such problems. In the developed method, we could embed adequate amount of watermarking data than previous methods, which is numerically stable and safely from alteration.
