Analysis and Simulation on SVD-Based 3D Mesh Digital Watermark Algorithm

Abstract:

The paper mainly discusses the digital watermark algorithm for 3D grid model. Traditional algorithm cannot coordinate the contradiction between invisibility and robustness of digital watermark. In order to improve the security, this paper proposes a 3D grid digital watermark algorithm based on singular value decomposition (SVD). Firstly, we set the matrix formed by distance from the vertexes to center of 3D mesh model as the vertex modulus matrix. Then the matrix is decomposed by SVD, and finally the watermark is embedded into the diagonal matrix to get the 3D mesh model containing watermark signal. The simulation results show that the algorithm effectively solves the problem of invisibility and robustness of watermark, and the watermark formed here can resist various attacks which enforce the protection of 3D mesh models Rights.
