Singapore, a contacts tracing app, based on Bluetooth: tracing who you have been close to, is supposed to be different from logging your location. They only get the exact info about who you could have infected, nothing else. And it works perfectly either outdoors or indoor. Among all the logged contacts, it even allows to rank the probability of a contagion. The app’s name is “Trace Together”; late in March 2020, its developers also forked the protocol from their project, named it “Blue Trace”, and published it on Github with the name “Open Trace”;
Germany (mostly), contacts tracing, maybe an app: PEPP-PT is an honorable mention, despite it currently (March 2020) aggregates european nations on a declaration of intents, much more than showing working software. This manifesto focuses on preserving privacy and using Bluetooth in smartphones. However, they demonstrated a suitable organizational approach to the highly unpredictable situation. The absence of any other group demonstrating the same ability, made us believe it will easily reach a critical-mass among European governments. Or at least, it will become the place where to discuss and decide the future of internationally adopted outbreak-related information technology.
While the situation in the three asian countries is now reverting to a general lockdown, all their approaches had an impact, at least, in slowing-down the outbreak.
We tried to get in touch to gather more info,
to share our thoughts and the idea we came with to put it at work.
We applied to the a government “fast-call” (a grid to describe our solution)
We wrote to the PEPP-PT consortium to offer our help and get info (if any)
We asked some questions to the Bluetrace group (queued in a Zendesk)
