The rapid growth of Artificial Intelligence (AI) and Deep Learning mirrors an infectious phenomenon. While AI systems promise diverse applications and benefits, they bear substantial security and privacy risks. Indeed, AI represents a goldmine for the security and privacy research domain.
This talk focuses on Federated Learning (FL), an innovative approach to enable collaborative Deep Neural Network training among distributed entities without sharing raw data. However, externalizing the training process exposes the system to malicious attacks, particularly poisoning attacks. Despite a significant body of research on FL attacks and defenses, poisoning attacks persist due to the limitations of current defense strategies.
We provide a systematic overview of FL attacks and defenses, including our contributions, highlighting their strengths and weaknesses, and explore ongoing challenges in fortifying collaborative learning frameworks.
We conclude by extending the discussion to the potential deployment of Federated Learning for detecting AI-generated text, where we present our recent work on effectively identifying ChatGPT-generated, substantially advancing the state-of-the-art.
