EN A new topology-based watermarking method is proposed to embed information in objects with layered 3D triangular meshes such as those reconstructed from CT or MRI data. The main idea of the method is to compare the heights of the vertices of a triangle lying in the same layer. A watermark message is converted into a binary bit sequence, and then embedded into the modelin such a way that the first vertex of a triangle in the upper level carries information 1, and the first vertex of a triangle in the lower level carries information 0. For experimental purposes, a watermark message is embedded in a mouse embryo model. It is robust against translation, rotation, re-sectioning, local deformation and scaling. It left some artifacts after re-arrangement of local or global numbering. It is useful for shape sensitive 3D geometric models.
