解决所有权死锁的一种数字水印算法

Authentic Watermarking Algorithm Based on Resolving Copyright Deadlock

  • 摘要: 为解决数字水印技术中广泛存在的所有权死锁问题,提出一种可靠的水印算法。通过引入Chebyshev和Henon混沌系统,结合非盲水印策略,得到密钥k1和k2,其中k1与混沌系统初值有关,容易获取;k2与原始图像有关,必须通过原始图像获取相应信息,即k2的获得具有唯一性,非版权人在一般情况下不可能获得k2,从而起到作品版权保护的目的。实验测试分析所提出的算法表明,该算法具有较高的鲁棒性和可靠性,完全能达到理论分析中所提到的作品版权保护目的。

     

    Abstract: Based on an application of the digital image watermarking of the wavelet and chaotic theory, an watermarking method is proposed to resolve copyright deadlock. By using Chebyshev and Henon chaose system with non-blind watermarking, Keys K1 and K2 are obtained, where K1 correlates with the initial value of chaose system, and K2 with the initial image. Experiments indicate that the proposed algorithm is effective and superior to the traditional algorithms.
