The custodians of the well-designed brushed-metal prisons that are Apple products not only want the power to disable your property, but also to spy on you.
If there was ever a reason to have control over the technology in your pocket, this would be it:
"Essentially, Apple's patent provides for a device to investigate a user's identity, ostensibly to determine if and when that user is "unauthorized," or, in other words, stolen. More specifically, the technology would allow Apple to record the voice of the device's user, take a photo of the device's user's current location or even detect and record the heartbeat of the device's user. Once an unauthorized user is identified, Apple could wipe the device and remotely store the user's "sensitive data." Apple's patent application suggests it may use the technology not just to limit "unauthorized" uses of its phones but also shut down the phone if and when it has been stolen.
However, Apple's new technology would do much more. This patented device enables Apple to secretly collect, store and potentially use sensitive biometric information about you. This is dangerous in two ways: First, it is far more than what is needed just to protect you against a lost or stolen phone. It's extremely privacy-invasive and it puts you at great risk if Apple's data on you are compromised. But it's not only the biometric data that are a concern. Second, Apple's technology includes various types of usage monitoring — also very privacy-invasive. This patented process could be used to retaliate against you if you jailbreak or tinker with your device in ways that Apple views as "unauthorized" even if it is perfectly legal under copyright law."
Says the Electronic Frontier Foundation. They conclude:
"This patent is downright creepy and invasive — certainly far more than would be needed to respond to the possible loss of a phone. Spyware, and its new cousin traitorware, will hurt customers and companies alike — Apple should shelve this idea before it backfires on both it and its customers."
