On a potential iPhone security panic button
May 17th 2016
Macworld:
In this week's iPhone Show, we look into an Apple patent that would give iPhones a new "panic mode" to lock out personal information or reset the device entirely. You'd be able to designate a certain finger for Touch ID to secretly trigger panic mode.
I think it would be a great idea to disable Touch ID with such a panic mode. Even better would essentially reboot the device to be fully locked with encryption. Either way the full password/phrase would be needed to unlock the device, and the later would likely reduce the chances of a screen lock exploit.
