A widely distributed Bluetooth monitoring network noting tims and places ... might ... be able to correlate secrets with other data (facial recognition, MAC, UUID, etc.,) to correlate individual with probable SARS-COV-2 exposure status.

An in-location tracking system, such as numerous proposed retail monitoring systems, among othe.

Given time and location, a low number of hits would likely be sufficient.

This would be expensive, but likely within reason for a motivated entity. Possibly by utilising (with or without cooperation) existing infrastructure and systems.

If you have a widespread Bluetooth monitoring network with centralized data you've already built your stalking system that likely works better than trying to use the Google/Apple contact tracing system.

But you've added Covid status detection as a capability. To what net advantage is unclear.

Though yes, this shows the inherent risks of pervasive surveillance systems.

If you have those resources, there are far more effective ways to track people that do not require relying on the contact tracing system.

Fair point.

The objective is far less practicality or usefulness than of determining possible attacks on the anonymous contact tracing method. Also incidentally highlighting the power and threats of widely-distributed surveillance networks. Inference is powerful.
