Singapore introduces contact tracing app to slow coronavirus spread (ZDNet) (Alt)
Government launches TraceTogether mobile app that taps Bluetooth signals to capture data of other participating devices in close proximity, enabling the encrypted information to be extracted to facilitate contact tracing should users contract the coronavirus. The app is able to estimate the distance between TraceTogether smartphones as well as the duration of such interactions. The data then is captured, encrypted, and stored locally on the user's phone for 21 days, which spans the incubation period of the virus.
