iOS 8 strikes an unexpected blow against location tracking

It wasn’t touted onstage, but a new iOS 8 feature is set to cause havoc for location trackers, and score a major win for privacy. As spotted by Frederic Jacobs, the changes have to do with the MAC address used to identify devices within networks. When iOS 8 devices look for a connection, they randomize that address, effectively disguising any trace of the real device until it decides to connect to a network.

“Any phone using iOS 8 will be invisible to the process”

Why are iPhones checking out Wi-Fi networks in disguise? Because there’s an entire industry devoted to tracking customers through that signal. As The New York Times reported last summer, shops from Nordstrom’s to JC Penney have tried out the system. (London even tried out a system using public trash cans.) The system automatically logs any phone within Wi-Fi range, giving stores a complete record of who walked into the shop and when. But any phone using iOS 8 will be invisible to the process, potentially calling the whole system into question.

  1. I don’t think that Apple is doing thid for privacy, but in order to push retailers to use its iBeacon technology. And surely turning wifi off will prevent this sort of snooping?
