【摘要】 置乱技术是随着信息安全与保密被重视而发展起来的图像加密技术.研究了置乱技术在信息隐藏特别是数字水印中的应用,通过置乱技术,一方面可以达到使非法使用者无法破译图像内容的目的,另一方面可以分散错误比特的分布,从而提高数字水印的鲁棒性.实验结果表明,置乱技术在抵抗剪切攻击方面是非常有效的.更多还原

【Abstract】 The application of shuffling techniques refers to the picture scurity technique with the development of information security. In this paper, shuffling techniques has been studied especially in the application of digital watermarking. With shuffling techniques, you can not only reach the purpose of preventing the illegal user from riddling the content of images, but also disperse the distributing of error bits in order to improve robust. Experimental results indicate that these techniques are very effective in keeping resilience to cropping attack.更多还原
