Digital Contact Tracing: Decentralized Privacy Protocols

This lecture covers the DP-3T protocol for digital contact tracing, focusing on decentralized privacy-preserving proximity tracing. It discusses the challenges of traditional contact tracing methods and the need for efficient notification systems in crowded environments. The protocol ensures privacy, abuse-resistance, and scalability, addressing the potential of airborne transmission in the COVID-19 pandemic. It also explores the CrowdNotifier protocol, designed to complement manual tracing by notifying individuals of potential exposure. The lecture emphasizes the importance of protecting privacy while effectively tracing contacts in various settings, such as restaurants, bars, and events. Additionally, it highlights the collaboration of multiple institutions in developing deployable solutions for contact tracing beyond mobile devices.
