In this “fireside video chat”, Matt Green and Yehuda Lindell will discuss location tracking in the context of COVID-19 and the privacy threats involved. This topic has come to the forefront again due to the proposals in multiple countries to use widespread location tracking in order to locate people who have come in contact with someone who has contracted COVID-19. The discussion will cover whether or not such use is legitimate, what the dangers are and whether they should be accepted, and finally what technological (cryptographic) solutions could be developed in order to achieve the desired affect without compromising on privacy.
