A dramatic influx of diffusion-generated images has marked recent years,
posing unique challenges to current detection technologies. While the task of
identifying these images falls under binary classification, a seemingly
straightforward category, the computational load is significant when employing
the "reconstruction then compare" technique. This approach, known as DIRE
(Diffusion Reconstruction Error), not only identifies diffusion-generated
images but also detects those produced by GANs, highlighting the technique's
broad applicability. To address the computational challenges and improve
efficiency, we propose distilling the knowledge embedded in diffusion models to
develop rapid deepfake detection models. Our approach, aimed at creating a
small, fast, cheap, and lightweight diffusion synthesized deepfake detector,
maintains robust performance while significantly reducing operational demands.
Maintaining performance, our experimental results indicate an inference speed
3.2 times faster than the existing DIRE framework. This advance not only
enhances the practicality of deploying these systems in real-world settings but
also paves the way for future research endeavors that seek to leverage
diffusion model knowledge.

DistilDIRE: A Small, Fast, Cheap and Lightweight Diffusion Synthesized  Deepfake Detection

Detecting diffusion-generated images has recently grown into an emerging
research area. Existing diffusion-based datasets predominantly focus on general
image generation. However, facial forgeries, which pose a more severe social
risk, have remained less explored thus far. To address this gap, this paper
introduces DiFF, a comprehensive dataset dedicated to face-focused
diffusion-generated images. DiFF comprises over 500,000 images that are
synthesized using thirteen distinct generation methods under four conditions.
In particular, this dataset leverages 30,000 carefully collected textual and
visual prompts, ensuring the synthesis of images with both high fidelity and
semantic consistency. We conduct extensive experiments on the DiFF dataset via
a human test and several representative forgery detection methods. The results
demonstrate that the binary detection accuracy of both human observers and
automated detectors often falls below 30%, shedding light on the challenges in
detecting diffusion-generated facial forgeries. Furthermore, we propose an edge
graph regularization approach to effectively enhance the generalization
capability of existing detectors.

通过引入 DiFF 数据集，本文首次探索了面向脸部的扩散生成图像的领域，分析结果揭示了识别扩散生成的假脸面临的挑战，并提出了一种边缘图正则化方法来增强现有检测器的泛化能力。
