摘要
提出一种新的基于Arnold图像置乱和小波变换相结合的数字水印算法.首先将水印图像Arnold置乱,然后按一定规则把水印信息分散嵌入到数字产品中.该算法通过各种攻击测试,对JPEG有损压缩、中值滤波攻击和高强度噪声攻击具有强稳健性,具有很好的透明性和鲁棒性,实用性也较高.
It is represented that a new digital watermark algorithm based on Arnold image-scrambling and wavelet transform. The watermark information is scrambled firstly and then embedded into the digital images in distribution with a certain method. Have carried on various attack test to the algorithm put forward. Experiment indicate algorithm this diminish compress, hit to JPEG value strain wave attack with high strength noise attacking, having strong and getting sane, have very good transparency and stupid and excellent, practicability is relatively high.
