摘要:

随着图像和视频合成的深度生成模型取得重大进展,Deepfakes和篡改媒体引发了严重的社会关注。用于Deepfake检测的传统机器学习分类器通常无法应对不断演进的Deepfake生成技术,且易受对抗性攻击影响。作为替代方案,不可见图像水印作为一种主动防御技术被研究,它通过验证嵌入在图像像素中的不可见秘密信息来进行媒体认证。少数用于媒体认证的不可见图像水印技术已被证明容易受到基本图像处理操作和水印移除攻击的影响。作为回应,我们提出了一种半脆弱图像水印技术,将不可见秘密信息嵌入真实图像以进行媒体认证。我们提出的水印框架设计为对面部篡改或篡改脆弱,同时对良性图像处理操作和水印移除攻击具有鲁棒性。这通过我们提出技术的独特架构实现,该架构包含critic和对抗网络,分别强制执行高图像质量和对水印移除工作的抗性,以及骨干编码器-解码器和判别器网络。在SOTA面部Deepfake数据集上的全面实验调查表明,我们提出的模型能将$64$位秘密作为不可察觉的图像水印嵌入,在应用良性图像处理操作时能以高比特恢复精度恢复,而在应用未见Deepfake篡改时不可恢复。此外,我们提出的水印技术对多种白盒和黑盒水印移除攻击表现出高抗性。从而获得了最先进的性能。

英文摘要:

With the significant advances in deep generative models for image and video synthesis, Deepfakes and manipulated media have raised severe societal concerns. Conventional machine learning classifiers for deepfake detection often fail to cope with evolving deepfake generation technology and are susceptible to adversarial attacks. Alternatively, invisible image watermarking is being researched as a proactive defense technique that allows media authentication by verifying an invisible secret message embedded in the image pixels. A handful of invisible image watermarking techniques introduced for media authentication have proven vulnerable to basic image processing operations and watermark removal attacks. In response, we have proposed a semi-fragile image watermarking technique that embeds an invisible secret message into real images for media authentication. Our proposed watermarking framework is designed to be fragile to facial manipulations or tampering while being robust to benign image-processing operations and watermark removal attacks. This is facilitated through a unique architecture of our proposed technique consisting of critic and adversarial networks that enforce high image quality and resiliency to watermark removal efforts, respectively, along with the backbone encoder-decoder and the discriminator networks. Thorough experimental investigations on SOTA facial Deepfake datasets demonstrate that our proposed model can embed a $64$-bit secret as an imperceptible image watermark that can be recovered with a high-bit recovery accuracy when benign image processing operations are applied while being non-recoverable when unseen Deepfake manipulations are applied. In addition, our proposed watermarking technique demonstrates high resilience to several white-box and black-box watermark removal attacks. Thus, obtaining state-of-the-art performance.
