Knowing how many people in the area have the Covid-19 contact tracing app installed
So I got distracted again. That post about ADSB is going to be delayed a bit.
In the past I was already fascinated by a project that allows to collect anonymised data about the amount of Bluetooth Low Energy (BLE) devices in range. You know, wireless headsets, smartphones, those kind. All GDPR-safe but ultimately boring. If I want to know how busy it is I can also look out of the window. But recently the project got a VERY interesting addition: It can identify a Covid-19 tracer app by it’s digital signature! Now I will be able to create a graph of total devices observed vs devices that have the Covid tracer app installed.
Well seriously, aren’t you just even a little bit curious about this?
And because the project does not collect ANY data that can be traced back to a device like a mac address or anything like ghat this is anonymous tracking of an anonymous app that is promising everybody that we are truly anonymous.
