The video makes constant references to "the location service", which<br>
appears to track your location both outdoors (GPS?) and indoors (wifi? What if I don't turn it on?). For cases (2) and (3) to work, my<br>
understanding is that both person 1 and 2 need to be connected to the same service, suggesting a central service? And you state that the device contains an "encrypted record that is a function of their<br>
identity". So basically, you're suggesting a central service that<br>
identifies and tracks people everywhere they go?<br></blockquote><div><br></div><div>Such constraints actually might work well in a medical facility (which is the example David gives). Rooms can be delineated not by Bluetooth beacons or WIFI, but simply by door access badges (although that involves employee tracking concerns). Regarding anonymity, would it not presumably be expected that healthcare workers exposed to COVID-19 be identifiable anyway to peers/employers (for the protection of patients and the workers own welfare, e.g. testing and sick leave)? <br></div><div><br></div><div>Zach<br></div></div></div>
