Sorry, I still don't understand how the system you describe in that video would work at scale, nor how it protects people's privacy.
The video makes constant references to "the location service", which 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 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 identity". So basically, you're suggesting a central service that identifies and tracks people everywhere they go? I also don't see how the system would work at scale. In example (1), rooms 1 and 2 are marked as contaminated simply because the person "was feeling under the weather". How would this not lead to huge false positives in practice? And how does the system protect itself from people gaming it? What prevents me from submitting records pretending I was "feeling under the weather" everywhere I went? The video then states "this shows how risk avoidance operates when we have a confirmed illness", but we have nothing. The problem with false positives is worsened in the last example, where the third room is marked "potentially" contaminated simply because person 2 had been in there after being in room 2, when the other person 1 had also been in room 2 "feeling under the weather". So far, all I see here is a surveillance system that tracks people really well, and does everything else rather poorly.
