Interview with Carmela Troncoso (EPFL), who led the design of the decentralised, privacy-preserving DP-3T protocol underlying the SwissCovid contact-tracing app. It explains how the app was designed to minimise data collection and avoid central databases. Cited in the e-ID taxonomy as a Swiss precedent for privacy-by-design in a large-scale public digital system.
