Germany copies Singapore's TraceTogether app for contact tracing
Researchers at Germany's Robert Koch Institute and Fraunhofer Heinrich Hertz Institute are working on an app that uses Bluetooth connections between smartphones and is compliant with GDPR to anonymously save the distance and duration of contact between people on the smartphone to make it possible to digitally reconstruct infection chains. The idea is being copied from Singapore's TraceTogether app, which detects other users who have also installed the app. If someone tests positive, they can opt to send the stored data to the health authorities, who can decrypt it and notify the contacts concerned via their phones. To date, 685,000 Singaporeans - more than 10% of the population - have installed the app.
