Multiple Blind Watermark Algorithm Based on Wavelet Packet Transform and Two-dimensional Chaos Scramble

摘要：

　　In this paper,multiple blind watermark algorithm based on wavelet packet transform (WPT) and two-dimensional chaos image scramble is put forward.In the sub-images of WPT,multiple watermarks are embedded and distilled blindly.Meantime,the image contrast enhancement to hidden information before hand can improve its robustness effectively.In order to improve the security,two-dimensional chaos image scramble algorithm is designed.Experimental results show that the multiple blind watermark algorithm has good invisibleness,security and robustness to common image processing and noise attack.
