Adv-watermark:一种新的对抗性水印扰动算法

Adv-watermark: A Novel Watermark Perturbation for Adversarial Examples

Xiaojun Jia, Xingxing Wei, Xiaochun Cao, Xiaoguang Han

摘要:

最近的研究表明,向原始图像添加一些难以察觉的扰动可以欺骗深度学习模型。然而,电流对抗扰动通常以噪声的形式表现出来,因此没有实际意义。图像水印是一种广泛应用于版权保护的技术。我们可以把图像水印看作是一种有意义的噪声,将其加入到原始图像中不会影响人们对图像内容的理解,也不会引起人们的怀疑。因此,使用水印生成对抗性示例将是有趣的。在本文中,我们提出了一种新的水印扰动对抗的例子(Adv-watermark),结合图像水印技术和对抗的例子算法。向干净图像添加有意义的水印可以攻击DNN模型。具体来说,我们提出了一种新的优化算法,这是所谓的盆地跳跃进化(BHE),在黑箱攻击模式下生成对抗性水印。由于BHE,Adv-watermark只需要从威胁模型中进行几次查询就可以完成攻击。在ImageNet和CASIA-WebFace数据集上进行的一系列实验表明,该方法可以有效地生成对抗性示例,并且优于最先进的攻击方法。此外,先进的水印是更强大的图像变换防御方法。

英文摘要:

Recent research has demonstrated that adding some imperceptible perturbations to original images can fool deep learning models. However, the current adversarial perturbations are usually shown in the form of noises, and thus have no practical meaning. Image watermark is a technique widely used for copyright protection. We can regard image watermark as a king of meaningful noises and adding it to the original image will not affect people's understanding of the image content, and will not arouse people's suspicion. Therefore, it will be interesting to generate adversarial examples using watermarks. In this paper, we propose a novel watermark perturbation for adversarial examples (Adv-watermark) which combines image watermarking techniques and adversarial example algorithms. Adding a meaningful watermark to the clean images can attack the DNN models. Specifically, we propose a novel optimization algorithm, which is called Basin Hopping Evolution (BHE), to generate adversarial watermarks in the black-box attack mode. Thanks to the BHE, Adv-watermark only requires a few queries from the threat models to finish the attacks. A series of experiments conducted on ImageNet and CASIA-WebFace datasets show that the proposed method can efficiently generate adversarial examples, and outperforms the state-of-the-art attack methods. Moreover, Adv-watermark is more robust against image transformation defense methods.
