基于多变换域融合的抗旋转攻击水印算法
Watermarking Algorithm Against Rotation Attack Based on Multi-Transform Domain
摘要
Abstract
To enhance the ability of transform domain digital watermarking to resist rotation attacks,the article proposes a watermarking algorithm that fuses multiple domains to resist arbitrary rotation angle attacks.First,the host image is subjected to DWT transformation,then the low-frequency coefficients of the last level are subjected to SVD,and finally,based on the size of the watermark information an appro-priate position in the singular value matrix is selected to embed the scrambled and encrypted watermark signal.The experimental results show that the algorithm has good watermark information hiding ability and can completely resist single rotation attacks ranging from 1°～360°.At the same time,it has strong robustness against combination attacks of image rotation attacks combined with cropping,JPEG com-pression and other attacks,and can effectively resist conventional signal processing.关键词
