- W2736706446 abstract "At present, zero-watermarking algorithms can well resist geometric attacks and signal attacks. However, most of them are not robust to resampling attack. To solve the problem, this paper presents a robust zero-watermarking algorithm for copyright protection of 3D triangular mesh models. The watermark information is constructed by spherical integral invariants and a new computing method based on spherical crown for the invariants is proposed. CPCA(Continues Principle Component Analysis) is introduced to normalize the input mesh, while Ray-Based method is introduced to decompose the normalized mesh into ordered patches. On one hand, for the model to be protected, once the watermark is constructed, it needs to be registered in a trusted third-party IPR(Intellectual Property Rights) database together with a timestamp. On the other hand, for the model to be detected, the constructed watermark should be matched with all watermarks to recognize whether its original model is in the database. Experimental results prove that it is robust against common geometric attacks, signal processing attacks and uniform resampling attack." @default.
