Towards Defeating Mass Surveillance and SARS-CoV-2: The Pronto-C2 Fully Decentralized Automatic Contact Tracing System
Year: 2021
Type: conference-paper
Abstract: Automatic contact tracing is currently used in several countries in order to limit the spread of SARS-CoV-2. \nMany governments decided to develop smartphone apps based \non the “Exposure Notifications” designed by Apple and Google \naccording to a decentralized approach previously proposed by \nthe DP-3T team. Decentralization was pushed as a key feature to \nprotect privacy in contrast to centralized approaches that could \nleverage automatic contact tracing to realize mass-surveillance \nprograms. \nIn this work, taking into account the privacy and integrity \nvulnerabilities of DP-3T systems, we show the design of a decentralized contact tracing system named Pronto-C2 that has better \nresilience against various attacks. We also discuss the significant \noverhead of Pronto-C2 when used in real-world scenarios.
