摘要
随着数字水印的不断被应用,在一些情况下数字水印受到攻击次数及种类也越来越多,其中解释攻击和拷贝攻击造成的危害日益严重,而这两种恶意攻击都属于协议层面的攻击,这也成了亟待解决的问题;提出了一种用原始图像的图像数字签名作为水印并结合双水印系统机制的数字水印算法,该算法巧妙地解决了上述问题;最后,经过仿真实验证明该算法可以很好地抵抗以上两种协议的攻击,在提高了数字水印的安全性方面起到了一定的作用。
With the development of digital watermark,it faces more attacks in practice then ever before,and harms of interpretation attack and copy interpretation are more and more regarded.Both of them belong to protocol attacks,and it must be solved.In this paper,a design scheme for watermark is presented with image signature as watermark and based on dual-watermarking,and it has good security of the digital watermarking.
