Security Enhancement for Person Re-Identification Through Diffusion Driven Semantic Attacks

Summary

Researchers propose DSCA, a Diffusion-based Semantic Camouflage Attack against person re-identification (ReID). Instead of perturbing pixels, a conditional diffusion generator edits latent attributes such as clothing color and texture to impersonate a target identity, operating zero-query and black-box. Experiments on major ReID benchmarks report attack success rates over 95% in their setting, along with evasion of advanced defenses.
