摘    要:本文提出一种基于混沌加密的频率域数字图像水印新算法.将含有版权信息的二值图像作为水印,利用混沌密码对其进行加密.利用人类视觉系统(HVS)的特性,实现了水印在原始宿主图像小波域中的自适应嵌入.实验结果证明了对常见噪音和图像处理算法,该水印具有良好的不可见性和鲁棒性.

关 键 词:混沌  DWT  HVS  二值图像数字水印  信息隐藏

Abstract:In this paper,we propose an image digital watermarking algorithm based on chaotic encryption in frequency do-main. A binary image carrying copyright information is used as watermarking and is encrypted by a chaotic sequence cipher before it is embedded. Using characteristics of human visual system (HVS),watermark is embedded into the original image in DWT domain. The experimental results show that the watermarks are invisible and robust against noises and common im-age processing methods.
Keywords:DWT  HVS
