| 摘 要： | 基于数字图像的奇异值分解和Arnold置换，提出了一种图像的隐藏方法．在该方法中，置乱用于数字图像隐藏的预处理和后处理，奇异值分解用于将一幅图像隐藏于另一幅图像中．根据提出的数字图像隐藏技术，探讨了在数字水印技术中的应用．实验结果显示，该方法实现方便，水印的提取不需要原图像，并能较好地保障数据的安全性。

| Abstract: | A novel digital image information hiding scheme based on digital image scrambling and matrix singular value is presented. In the scheme, scrambling technology is used as pre-processing and post-processing of digital image information hiding, and SVD is used to hide one image into another. In addition, how to use the scheme into the research area of digital image watermarking is also discussed. The experimental results show that the scheme can be easily realized. It does not need original image for watermark drawing, but still well guarantees the safety of data. |
