Hamming Code Based Watermarking Scheme for 3D Model Verification

The technique of 3D modeling and the Internet progress quickly, the issue of the copyright of 3D models has become more and more important. There is a public hamming code based fragile watermarking technique proposed in this paper. The target of this article is to verify the authenticity of the model. An adaptive watermark is generated by using hamming code which extract some specific data from each cover model. The watermark is then embedded into the model. Using hamming procedure to generate watermark do not need original model and watermark information for verification in extracted stage. Experimental results show that the embedding rate achieve 100%. And the distortion of every stego model can be controlled below 10^-10.
