Abstract : An original hierarchical watermarking scheme is proposed in this paper. A geometrically robust watermark and a high-capacity watermark are inserted in different resolution levels of the wavelet decomposition of a semi-regular mesh. Both these watermarks are blind and invariant to similarity transformations. The robustness of the first watermark is achieved by synchronizing and quantizing watermark primitives by using edges lengths of the coarsest level. And the high capacity of the second watermark is obtained by watermarking the permutation of the norms of a group of wavelet coefficients. Experiments have proven the high robustness of the first watermark under common geometrical attacks. And to our knowledge, the capacity of the second method, which is equal to the factorial of the candidate coefficients number, is the highest for 3D meshes in the literature.
