摘要
提出了一种小波域双水印算法,并用MATLAB予以实现,随后的仿真攻击实验证明了该算法对几种一般攻击具有很好的鲁棒性,不仅在版权维护方面将发挥很好的作用,而且还能发现任何非法用户的恶意修改。
In this paper, a dual watermarking technique in the DWT domain is suggested and implemented using the MATLAB software. The measured performance of the technique proves its robustness against several kinds of attacks. Hence it can serve as a good means to prove the authenticity and ownership of intellectual properties and it can also detect any alteration or modification by any illicit user.
