Robust Animation Zero Watermarking Based on Visual Cryptography and Complete Complementary Code

In this paper, the experiment use common animation fragments of network as the original vector video. Firstly, we randomly select some frames from the vector video frames to embed the watermarking information. Secondly, the 2D DWT and pseudo 3D DCT transform is chosen as the processing mode to process vector video frames in the processing of transform domain. In addition, using the log polar coordinate transformation and singular value decomposition process vector video to get a binary sequence. Thirdly, in order to enhance the robustness and security of zero watermarking, we use the complete complementary code to spread spectrum the watermarking signal, and use the visual cryptography to encrypt and decompose the secret watermarking image under chaotic scrambling. Finally, in order to verify the robustness and feasibility of algorithm, we carry on the contrast experiment of two algorithms. It shows that this paper algorithm is improved against Gaussian noise, filtering and frame averaging attacks.
