Quite interesting article. I guess the take away is that I need to start disabling wifi when leaving my house?
I wonder if that can be done in some automatic way.
- oakesm9 3y agoThis data was collected by O2 on their customers, so I presume the data comes from what cell site you’re phone is connected to. To avoid this you’d need to have mobile data disabled or just leave your phone at home. TfL collected a separate dataset themselves using WiFi access points in the underground (covered later in the article).

- rightbyte 3y agoMaybe the app sends requests with some timing tied to the user id? With spyware on the telephone, it should be possible to do some scheme to circumvent mac address hopping.
