“The longer they keep the data and the more data points you have, the more you can learn about a person’s behavior — where someone goes to church, what doctors they have or where they slept at night,” said Dave Maass, an investigative researcher at the Electronic Frontier Foundation, a privacy watchdog group. “Maybe we can predict where somebody is going to be, and we can tell you who their associates are. It can be very invasive over time.”
