A research paper details a team's participation in the ImageCLEF 2026 Deepfake Detection and Generation Task, employing FLUX.1-dev with PuLID for identity-preserving face synthesis and a multi-model PGD adversarial attack. Their generation approach achieved 90% evasion against organizer detectors. For detection, they combined SigLIP+DINOv2 and GenD-DINOv3 detectors, reaching 99.4% accuracy on baseline deepfakes but with high false-positive rates on real images. Further investigation into purification-based adversarial detection revealed that raw $|\Delta \text{logit}|$ under median-3 purification, applied through the EFFORT detector, effectively separates adversarial inputs from clean ones, refuting the simple backbone-preservation hypothesis.
