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

Abstract:

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.
