  • To clarify, i reread, and the article does say they are buying the data from Fog Data. I’ve read elsewhere that Fog Data logs location data from installed apps using location services. I don’t know if that’s the only method Fog Data uses. If it is, turning off location services should significantly impair this approach. Airplane mode would not, though it would probably prevent radio triangulation like you describe.

    My comment was that there are a lot of ways that phones record location data, and no single countermeasure stops all of them. In addition to apps using location services, the phones themselves track you in a lot of different ways. For example iPhones continuously monitor and log location data even when the phone is off. They use BTLE mesh when other methods are unavailable.
















  • Beyond Apple and Google collecting it, there are thousands of apps people install that ask for location information that sell the data. Companies like Anomaly 6 claim that they get location data on over 3 billion of handsets from app-based location tracking.

    On the article headline… it’s a huge enhancement to the capabilities we’ve already known. We’ve known for some time that phones can be passively tracked based on the saved Wifi networks they attempt to auto-connect to. This development suggests we can track humans (not electronics) based on the observed disturbance the human meat causes to the wifi signal. If it works and is as accurate as the researchers claim (something I’d be suspicious of), that’s a pretty big deal.
