AI Technical Summary

Technical Problem

Existing technologies lack effective detection schemes for adversarial security detection of multimodal large models, especially in non-white-box scenarios. Furthermore, existing methods fail to fully utilize the synergistic effects between multimodal data, resulting in incomplete adversarial security detection.

Method used

A multimodal large-scale adversarial security detection system was designed. By combining an image and text adversarial sample generation module with a multimodal task testing module, multimodal collaborative adversarial samples are generated. Security assessment can be performed by only knowing the structural information of the front-end multimodal encoder.

Benefits of technology

It realizes multimodal large model adversarial security detection in non-white-box scenarios, can comprehensively evaluate the security performance of the model, and supports the generation of adversarial examples for various multimodal data, with good scalability.
