Scaling Exposes the Trigger: Input-Level Backdoor Detection in Text-to-Image Diffusion Models via Cross-Attention Scaling

Researchers have identified a new method to detect backdoor attacks in text-to-image diffusion models through cross-attention scaling, revealing systematic differences between benign and compromised inputs. This development is crucial for developers as it enhances security against stealthy, semantics-preserving triggers without needing prior knowledge of the attack specifics, offering robust protection in open ecosystems.
