iOS 8 strikes an unexpected blow against location tracking:
It wasn’t touted on-stage, but a new iOS 8 feature is set to cause havok 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.
Good: Apple is demonstrably improving an aspect of wifi privacy. Kudos to them!
However: Retailers are using Bluetooth to engage in the same activity, so ideally a similar privacy enhancing technique will be designed when Bluetooth functionality is turned on.
Depressing Reality: I’ll really believe that Apple is invested in privacy when they enable/initiate similar privacy by design functions in their own physical environment system, iBeacons.
