Trigger color significantly impacts federated learning backdoor attack success

Researchers have explored how the color of visual triggers impacts the success rate of backdoor attacks in federated learning systems. Their study, focusing on semantic triggers like masks and sunglasses, found that manipulating only the trigger color significantly altered attack effectiveness, even when other factors like trigger semantics and poisoning budget remained constant. Experiments on the CelebA dataset indicated that white triggers were more successful for targeting lighter hair colors, while black triggers performed better for darker hair colors, demonstrating that trigger color is a crucial element in the design and evaluation of these attacks.
