New VLM-driven defense framework PRISM targets backdoor attacks

Researchers have introduced PRISM, a novel framework for defending against backdoor attacks on deep neural networks. This approach shifts from internal model diagnosis to external semantic auditing, utilizing Universal Vision-Language Models (VLMs) as independent security auditors. PRISM refines visual prototypes online and uses an adaptive router for real-time threshold calibration, demonstrating state-of-the-art performance in suppressing attack success rates while maintaining clean accuracy.
