用于版权保护的数字图像水印技术已经变得越来越鲁棒。最好的算法在Stirmark包中包含的标准基准测试中表现良好。然而，stirmark测试是有限的，因为一般来说，他们没有正确地模型的水印处理，因此是有限的，在他们的潜力，以消除最好的水印。在这里，我们提出了一个随机制定的水印攻击使用的估计为基础的概念。提出的攻击包括两个主要阶段：a）水印或覆盖数据估计; B）修改隐写数据，目的是破坏水印检测和解决版权，考虑到嵌入水印的统计信息，并利用人类视觉系统的功能。在本文的第二部分，我们提出了一个“第二代基准”。我们遵循Stirmark基准的模型，并提出了以下6类测试：去噪攻击和小波压缩，水印复制攻击，同步删除，去噪/压缩与以下感知重新调制，去噪和随机[...]
Digital image watermarking techniques for copyright protection have become increasingly robust. The best algorithms perform well against the now standard benchmark tests included in the Stirmark package. However the stirmark tests are limited since in general they do not properly model the watermarking process and consequently are limited in their potential to removing the best watermarks. Here we propose a stochastic formulation of watermarking attacks using an estimationbased concept. The proposed attacks consist of two main stages: a) watermark or cover data estimation; b) modification of stego data aiming at disrupting the watermark detection and of resolving copyrights, taking into account the statistics of the embedded watermark and exploits features of human visual system. In the second part of the paper we propose a "second generation benchmark". We follow the model of the Stirmark benchmark and propose the 6 following categories of tests: denoising attacks and wavelet compression, watermark copy attack, synchronization removal, denoising/compression with following perceptual remodulation, denoising and random [...]
