If you installed an app during the pandemic to alert you if had contact with someone who’d tested positive for the virus, thank Carmela Troncoso. Her work on the Decentralized Privacy-Preserving Proximity Tracing system, or DP-3T, made passive contact tracing easy without asking citizens to surrender private data. It stores temporary, anonymized contact data on phones instead of a server, which makes hacks and data mining hard. Apple and Google used this technology to develop their tools.
