Shocking article how easy it is to track anybody, including Donald Trump. A dataset with more than 50 billion location pings from the phones of more than 12 million Americans was used by NY Times. It contained the traces of a Secret Service agent that accompanied Donald Trump. The agent’s home was also clearly identifiable in the data.
Another search search turned up more than a dozen people visiting the Playboy Mansion. The NY Times could easily spot visitors to the estates of Johnny Depp, Tiger Woods and Arnold Schwarzenegger. And also connect the devices’ owners to the residences indefinitely.
