A Video Digital Watermarking Algorithm Based on Chaotic Maps

Abstract:

The scrambled watermark is embedded in DCT coefficients of low-frequency sub image with the Brightness Component of original color image after lifting wavelet transformation. Before embedding the watermark, the image confusion method is used to eliminate the space correlation of the pixels and improves the security and robustness. The results showed that the algorithm is easy to carry out with the real-time request of video watermarking.
