• Abstract: We study universal deepfake detection. Our goal is to detect synthetic images from a range of generative AI approaches, particularly from emerging ones which are unseen during training of the deepfake detector. Universal deepfake detection requires outstanding generalization capability. Motivated by recently proposed masked image modeling which has demonstrated excellent generalization in self-supervised pre-training, we make the first attempt to explore masked image modeling for universal deepfake detection. We study spatial and frequency domain masking in training deepfake detectors. Based on empirical analysis, we propose a novel deepfake detector via frequency masking. Our focus on frequency domain is different from the majority, which primarily target spatial domain detection. Our comparative analyses reveal substantial performance gains over existing methods. Code and models are publicly available.

  This research addresses the challenge of developing a universal deepfake detector that can effectively identify unseen deepfake images.

We introduce a novel frequency-aware approach called FreqNet, centered around frequency domain learning, specifically designed to enhance the generalizability of deepfake detectors.

  The emergence of deepfake technologies has become a matter of social concern as they pose threats to individual privacy and public security. It is almost impossible to collect sufficient representative fake faces, and it is hard for existing detectors to generalize to all types of manipulation. We propose Real Face Foundation Representation Learning (RFFR), which aims to learn a general representation from large-scale real face datasets.
