Abstract

Digital water marking, the technique for hiding information into multimedia contents, is attracting large attentions in the recent years. This paper proposes a new water marking technique for 3D geometric models. The new algorithm retriangulates a part of a triangle mesh and embeds the watermark into the positions of the newly added vertices. Up to 8 bytes data can be invisibly embedded into an edge of the triangle mesh without causing any changes to the geometry of the original 3D model. The embedded watermark resists affine transformation and can be extracted only from the stego-model without using the original cover model.
