LinkNYC [0] kiosks have two security cameras (one above each ad display on both sides). Would it be somehow, or very, paranoid to imagine that these kiosks are also capturing IMSIs using a method similar to the one described above?
If you join the wi-fi network that any kiosk advertises, you will definitely “re-attach” when you encounter a new kiosk (so some MAC related tracking is possible).
But... do municipal CCTV setups usually go beyond video only and attempt to track people using various methods around bluetooth/MAC/IMSI?
Is it probable? Improbable? We’ll only know in N years when someone leaks about it..? Has it already been done?
