Research on Digital Image Watermarking Scheme Based on Blind Source Separation
Zheng Chun-jiao · 2006
A digital image watermarking scheme embedded in spatial domain based on BSS(blind source separation) was proposed.To improve the robustness and security of watermarking data transmission,the method of spreading spectrum directly and chaotic sequence scrambling to generate a watermark was used.Then,using the mixing model and separating model based on BBS theory to realize the embedding and extracting watermark information.Finally,a lot of simulation experiments based on MATLAB were done.Experimental results expatiate that this method has a good transparency and much robust ness against common noise attacking,geometry attacking,JPEG compression and other images processing.This embedding scheme is quite simple and of good synchronization.So this scheme values very well in actual practice.
