Apple may be looking to lock out unauthorized iOS users
Apple has applied for a patent on a method to differentiate between authorized and unauthorized users of a particular iOS device. Once an unauthorized user is detected, the device can then automatically disable certain features or send notifications to Twitter or other services.
The patent, titled "Systems and Methods for Identifying Unauthorized Users of an Electronic Device," describes several ways a device could sense who is using an iPhone or iPad. Among the methods considered are voice print analysis, photo analysis, heartbeat analysis (!), hacking attempts, or even "noting particular activities that can indicate suspicious behavior."
