Image Encryption Algorithm Based on Arnold Image-Scrambling and Discrete Fourier Transform
Pages: 73-75
Year: Issue:  2
Journal: Journal of Tangshan Teachers College

Keyword:  DFT水印嵌入;
Abstract: 提出了一种新的基于Arnold图像置乱和离散傅立叶变换相结合的数字水印算法.首先将原始图像划分子块,对每一图像块进行DFT变换,将二值水印图像用Arnold变换置乱,然后按一定规则把水印信息分散嵌入到数字产品中.本算法复杂度较低,实用性较强.仿真结果证明其具有较好的鲁棒性和透明性以及抗JPEG压缩、旋转和噪声干扰能力.
