Abstract

In this paper, we propose a new fragile watermarking algorithm based on the global characteristics of the mesh geometry to authenticate 3D mesh models. In our method, a sequence of data bits is adaptively embedded into the mesh model by properly adjusting the vertex positions, and the bit information can be blindly extracted from the watermarked mesh model using a key. The embedding process is adaptive to the mesh model so that the watermarked mesh is perceptually indistinguishable from the original. We show that the embedded watermark is invariant to affine transformation but sensitive to other operations. Besides, the embedding strength is adjustable and can be controlled to a certain extent that even a trivial tampering with the watermarked mesh would lead the watermark signal to change. Therefore, unauthorized modifications of the mesh models can be detected and estimated.
