A European coalition of techies and scientists drawn from at least eight countries, and led by Germany’s Fraunhofer Heinrich Hertz Institute for telecoms (HHI), is working on contacts-tracing proximity technology for COVID-19 that’s designed to comply with the region’s strict privacy rules — officially unveiling the effort today.

China-style individual-level location-tracking of people by states via their smartphones even for a public health purpose is hard to imagine in Europe — which has a long history of legal protection for individual privacy. However the coronavirus pandemic is applying pressure to the region’s data protection model, as governments turn to data and mobile technologies to seek help with tracking the spread of the virus, supporting their public health response and mitigating wider social and economic impacts.
