It’s trivially easy to identify you based on records of your phone calls and texts
“Contrary to the claims of America’s top spies, the details of your phone calls and text messages—including when they took place and whom they involved—are no less revealing than the actual contents of those communications.
In a study published online Monday in the journal Proceedings of the National Academy of Sciences, Stanford University researchers demonstrated how they used publicly available sources—like Google searches and the paid background-check service Intelius—to identify “the overwhelming majority” of their 823 volunteers based only on their anonymized call and SMS metadata.
Using data collected through a special Android app, the Stanford researchers determined that they could easily identify people based on their call and message logs.
The results cast doubt on [show as lies] claims by senior intelligence officials that telephone and Internet “metadata”—information about communications, but not the content of those communications—should be subjected to a lower privacy threshold because it is less sensitive.”
