Steganography for Three-Dimensional Polygonal Meshes

This paper proposes a method to embed information into a 3D model represented by a polygonal mesh. The approach used consists in slightly changing the position of the vertices, in uencing the length of approximation of the normals to the surface. This technique exhibits relatively low complexity, and o ers robustness to simple geometric tranformations. In addition, it does not introduce any visible distortion to the original model.
