图像数字水印的攻击与评估

ATTACKS AND EVALUATION OF IMAGE DIGITAL WATERMARKING

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 。

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.
