🌟 What’s New?

We propose state-of-the-art solutions to enhance the robustness of Vision-Language Models (VLMs) against Gaussian noise and adversarial attacks. Key highlights include:

• —🎯 Robust-VLGuard: A pioneering multimodal safety dataset covering both aligned and misaligned image-text pair scenarios.

• —🛡️ DiffPure-VLM: A novel defense framework that leverages diffusion models to neutralize adversarial noise by transforming it into Gaussian-like noise, significantly improving VLM resilience.

✨ Key Contributions

• —🔍 Conducted a comprehensive vulnerability analysis revealing the sensitivity of mainstream VLMs to Gaussian noise.
• —📚 Developed Robust-VLGuard, a dataset designed to improve model robustness without compromising helpfulness or safety alignment.
• —⚙️ Introduced DiffPure-VLM, an effective pipeline for defending against complex optimization-based adversarial attacks.
• —📈 Demonstrated strong performance across multiple benchmarks, outperforming existing baseline methods.
