摘要
文章提出了基于混沌渐进同步思想的公钥鲁棒性数字水印算法。首先对混沌同步思想进行了简单介绍。然后提出了一种基于驱动-响应法混沌同步思想的二进制幅度键控的保密通信方案;利用该方案实现了将版权信息加载到混沌序列;并设计了一种以此序列作为水印信号的水印算法;试验证明算法思想可行。最后文章对算法的优缺点进行了讨论。
A novel public key robust digital watermarking algorithm based on asymptotic chaotic synchronization is proposed in this paper. First,the notion of asymptotic synchronization of chaos is introduced,and a 2ASK communication scheme is proposed,which is based on the theory of chaotic synchronization of driving-response.Then,the digital algorithm is implemented,in which the watermark is generated by using the 2ASK communication scheme. Experiments are done,and experimental results show that the ideal is reasonable. Finally,the advantage and disadvantage of this algorithm is discussed.
