Wasn't there some news days ago about a cyclist being on the suspect list of a burglary because he was cycling on the street next to a house and the app he was using was taking location data from Google?
US government could just order Google / Apple push an update to their OSes thereby making location data always on then gather the data and do contact tracing.
A lot of people would actually self-subscribe to a Google Contact Tracing app if they are instantly notified about crossing paths with an infected person.
They wouldn't even need to go that far. As long as the phone is talking to the tower its position is known. Perhaps a rise in mesh networks with non cellular devices will be a thing?
For a single data point itβs not that accurate but over time things change. How many people are within 500 feet of you for 4+ hours a day. In that mindset, building a model to track say every person on a tour bus seems rather straightforward. Even locating people likely to be having an affair seems doable if you have some basic biographic info on the general population.
