摘要:
 鲁棒性是水印的重要特性之一，水印鲁棒性强度恰当与否决定着水印的好坏。因此，水印鲁棒性衡量至关重要。文中提出了新的衡量水印算法，新算法将被攻击后的水印作为函数变量。首先对水印被攻击后给水印所造成的损坏进行分类，之后以原始水印作为衡量水印鲁棒性的基准，通过计算提取水印偏离原始水印程度的值，将所得到的值使用中介真值程度度量的方法对水印鲁棒性进行衡量。中介真值程度度量的方法在数字水印上的应用尚属首次。最后进行了算法分析。
Abstract:
 The robustness is one of the important characteristics of the watermark and the strength of watermark robustness determines the watermark. Therefore,the measurement of watermark robustness is important. Propose a new watermarking measure algorithm in this pa-per. The new algorithm uses the attacked watermark as a function variable. Classify the damaged watermarking caused by the attack and take the original watermarking as the baseline to measure the robustness of watermarking. After calculating the value of the distance be-tween the new watermarking and the original watermarking,use the ratio function and the measure of medium truth scale to measure the robustness of the watermarking. This is the first time to apply measure method of medium truth scale to watermarking. The analysis of the algorithm is also presented.
