摘要：
This paper proposed a perceptual hashing algorithm of robust blind watermarking method for volume data. Which address the problems of authentication and protection of personal information. The scheme obtains the feature vectors of volume data and quantizes them to generate the hash value of the volume data. By combining the concept of zero-watermarking, the algorithm for watermarking of volume data that is robust to geometric attacks. The experimental results demonstrate that the proposed algorithm has good invisibility and robustness.
