The rise of deepfake images, especially of well-known personalities, poses a
serious threat to the dissemination of authentic information. To tackle this,
we present a thorough investigation into how deepfakes are produced and how
they can be identified. The cornerstone of our research is a rich collection of
artificial celebrity faces, titled DeepFakeFace (DFF). We crafted the DFF
dataset using advanced diffusion models and have shared it with the community
through online platforms. This data serves as a robust foundation to train and
test algorithms designed to spot deepfakes. We carried out a thorough review of
the DFF dataset and suggest two evaluation methods to gauge the strength and
adaptability of deepfake recognition tools. The first method tests whether an
algorithm trained on one type of fake images can recognize those produced by
other methods. The second evaluates the algorithm's performance with imperfect
images, like those that are blurry, of low quality, or compressed. Given varied
results across deepfake methods and image changes, our findings stress the need
for better deepfake detectors. Our DFF dataset and tests aim to boost the
development of more effective tools against deepfakes.

通过对深度伪造图像的产生和检测进行深入研究，本论文提出了一种全面的深度伪造图像生成与识别的方法。在我们的研究中，我们创建了一个名为 DeepFakeFace (DFF) 的数据集，用于训练和测试检测深度伪造图像的算法。我们进行了对 DFF 数据集的全面评估，并提出了两种评估方法来测试深度伪造识别工具的强度和适应性。根据我们的发现，不同的深度伪造方法和图像变化产生了多种结果，突显了对深度伪造检测器的需求。我们的 DFF 数据集和测试旨在促进更有效的抵御深度伪造的工具的发展。
