The IBISC Laboratory is delighted to welcome Dr. Tianwei Zhang from the College of Computing and Data Science at Nanyang Technological University, Singapore. Invited by our colleague Hicham Hadj-Abdelkader, Dr. Zhang will deliver a seminar on the topic:
Trustworthy Agent Systems Powered by Generative AI Models.
This seminar will take place in a hybrid format on Tuesday, June 24, at 2:00 PM in Amphitheater Bx30 (Pelvoux site) for in-person attendees and remotely via the following Zoom link: https://univ-evry-fr.zoom.us/j/94987458825?pwd=sba4fQ1uFdaH9Y3SlezPaiePTy2ES5.1
Abstract
The rapid integration of large vision-language models (VLMs) into intelligent agent systems has unlocked remarkable capabilities across domains. These systems promise autonomy, adaptability, and multimodal understanding, positioning them at the frontier of real-world AI deployments. However, as their complexity and reach grow, so do the security and trustworthiness challenges they face. In this talk, I will explore the security and trustworthiness issues of contemporary VLM-driven agent systems, focusing on a range of emerging threats from adversarial perception attacks to prompt injections. I will illustrate how these vulnerabilities can be exploited in practice and what risks they pose to safety, privacy, and reliability. Then I will discuss some potential defensive strategies to enhance the resilience of these systems. This talk aims to provoke both technical insight and critical reflection on the secure development of next-generation AI agents.
