Invited by: António Casimiro

Abstract: Privacy-enhancing technologies (PETs) provide a crucial opportunity to harness the power of data while safeguarding data privacy. In this talk, I will first introduce searchable encryption and explore its applications in location-based services and genome data-oriented services. I will then explore how large language models (LLMs) are being applied in password cracking, and discuss the importance of preserving data deletion rights and the strategies to achieve this in federated learning. Lastly, I will present my ongoing cooperation project with LASIGE about adversarial machine learning in intrusion detection systems (IDS).
