图像数字水印的攻击与评估

近年来,随着多种图像数字水印算法的提出,有必要建立一系列评估算法性能的评估标准.本文列举了一系列对数字图像的攻击方法,提出了检验图像水印算法稳健性和不可见性的标准,并给出了空域法和基于小波法下图像水印质量的评估结果.

ATTACKS AND EVALUATION OF IMAGE DIGITAL WATERMARKING

In the last few years, digital watermarks have been proposed as a solution for solving the illegal copying and proof of ownership problem in the context of multimedia objects. But it is still difficult to have a rough standard of their performances and hence compare them. So we propose a benchmark to compare image watermarking on a fair basis.
