Explore privacy-preserving information sharing techniques and applications in this comprehensive lecture by Dr. Emiliano De Cristofaro from the Alan Turing Institute. Delve into secure computation methods, including two-party computation (2PC) and its implementation. Examine private set intersection (PSI) protocols, including straightforward PSI, oblivious pseudorandom functions, and PSI with data transfer. Investigate authorized private set intersection (APSI) and its security features. Learn about collaborative anomaly detection and other building blocks in privacy-enhancing technologies. Gain insights into the intersection of machine learning, security, and privacy from an expert in the field.
