Robust Watermarking for 3D Objects

Copyright protection of digital media is an important issue in the distribution of digital content. More and more interest is being taken in methods to protect the copyright of digital data and prevent illegal duplication of it. Digital watermarking technology allows users to embed specific information, identifying the owner, in the host data imperceptibly. After developing the theory and practical details of the Yu-Kwok's watermarking scheme, it is shown that this method will produce pathological case in some circumstances. Modification of the algorithm that will reduce this unwanted impact of the embedded watermark on the local geometry is proposed. The effectiveness of the proposed technique is then presented by the windows application for robust watermarking of 3D triangular mesh models that implements our modified algorithm.
