EurekAlert: Bluetooth signals from your smartphone could automate COVID-19 contact tracing

EurekAlert: Bluetooth signals from your smartphone could automate COVID-19 contact tracing. “A team led by MIT researchers and including experts from many institutions is developing a system that augments ‘manual’ contact tracing by public health officials, while preserving the privacy of all individuals. The system relies on short-range Bluetooth signals emitted from people’s smartphones. These signals represent random strings of numbers, likened to ‘chirps’ that other nearby smartphones can remember hearing.”
