Digital Watermarking Algorithm Based on Wavelet Analysis

摘要：

　　With the rapid development of the network and the multimedia technical,how to protect the security of the multimedia informations becomes the popular topic on studies.As a new technique used to protect the copyright of digital productions,the digital watermark technique has drawn extensive attention.A digital watermarking algorithm based on discrete wavelet transform (DWT) was presented according to human visual properties in the paper.Then some attack analyses were given.Experimental results show that the watermarking scheme proposed in this paper is invisible and robust to cropping,and also has good robustness to compression,filtering,and noise adding.
