摘要 提出一种新的将水印图像Arnold置乱算法,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 proposes a new Arnold scrambling watermark image algorithm,then embedded in digital products distributed according to certain rules of the watermark.The algorithm is tested through a variety of attacks.It has strong robustness against JPEG lossy compressionmedian,filtering attack,high-intensity noise attack.It has good transparency and robustness At the same time,it has higher utility.
