🗡️ OmniSafeBench-MM: A Unified Benchmark and Toolbox for Multimodal Jailbreak Attack–Defense Evaluation 🛡️
📰 News 📰
- [2024/02/06] 🚀 Initial release of OmniSafeBench-MM with 13 attack methods and 15 defense strategies 🚀
🗡️ What is OmniSafeBench-MM 🛡️
OmniSafeBench-MM is a unified benchmark and open-source toolbox for evaluating multimodal jailbreak attacks and defenses in Large Vision–Language Models (MLLMs). It integrates a large-scale dataset spanning 8–9 major risk domains and 50 fine-grained categories, supports three real-world prompt types (consultative, imperative, declarative), and implements 13 representative attack methods and 15 defense strategies in a modular pipeline. Beyond traditional ASR, it introduces a three-dimensional evaluation protocol measuring harmfulness, intent alignment, and response detail, enabling fine-grained safety–utility analysis. Tested across 18 open-source and closed-source MLLMs, OmniSafeBench-MM provides a comprehensive, reproducible, and extensible platform for benchmarking multimodal safety.
🌐 Overview 🌐
Overview of OmniSafeBench-MM. The benchmark unifies multi-modal jailbreak attack–defense evaluation, 13 attack and 15 defense methods, and a three-dimensional scoring protocol measuring harmfulness, alignment, and detail.
