本文提出一种新型人脸替换自编码器与融合技术生成高质量深度伪造,发现最先进检测器在现实场景中对此表现不佳,并证明用此类高质量样本微调可提升检测泛化能力。

摘要:

由于深度伪造对安全和隐私的威胁日益增加,开发稳健可靠的检测器变得最为重要。在本文中,我们检验了此类检测器的训练数据集中对高质量样本的需求。因此,我们展示了被证明在多个研究数据集上泛化良好的深度伪造检测器,在现实场景中面对精心制作的伪造品时仍然表现不佳。首先,我们提出了一种用于人脸替换的新型自编码器以及一种先进的人脸融合技术,我们利用它们生成了90个高质量深度伪造。其次,我们将这些伪造品输入到最先进的检测器中,导致其性能急剧下降。此外,我们在这些伪造品上微调了检测器,并证明它们包含用于检测篡改的有用线索。总体而言,我们的结果为深度伪造检测器的泛化能力提供了见解,并建议它们的训练数据集应补充高质量伪造品,因为仅依靠研究数据进行训练是不够的。

英文摘要:

Due to the rising threat of deepfakes to security and privacy, it is most important to develop robust and reliable detectors. In this paper, we examine the need for high-quality samples in the training datasets of such detectors. Accordingly, we show that deepfake detectors proven to generalize well on multiple research datasets still struggle in real-world scenarios with well-crafted fakes. First, we propose a novel autoencoder for face swapping alongside an advanced face blending technique, which we utilize to generate 90 high-quality deepfakes. Second, we feed those fakes to a state-of-the-art detector, causing its performance to decrease drastically. Moreover, we fine-tune the detector on our fakes and demonstrate that they contain useful clues for the detection of manipulations. Overall, our results provide insights into the generalization of deepfake detectors and suggest that their training datasets should be complemented by high-quality fakes since training on mere research data is insufficient.
