| 摘 要： | 数字水印是多媒体数字产品版权保护的重要技术之一。为了提高数字水印的鲁棒性,文中提出了一种在小波变换域中向图像嵌入水印的方法,而且该方法在水印提取时不需要原始图像。嵌入前对水印图像进行了Arnold置乱,消除像素的空间相关性,增强了图像抗攻击能力,提高了水印安全性。实验证明,算法对压缩、加噪、剪切等具有较高的鲁棒性。

| Abstract: | Digital watermarking is a technique for inserting information into digital multimedia.To increase the robustness,proposes a new method of digital watermarking for image signals based on the wavelet transform.This method does not require the original image in the proposal detection algorithm.Through Arnold transform,the watermarking image was hashed to eliminate the spatial correlation among pixels.The ability to with stand attacks was enhanced.The security of watermarking was enhanced too.The experimental results show that it is robust against JPEG compression,adding noise and cropping. |
