Regarding Intelligent Location-Based Security

John Gruber, commenting on, of all things, an Apple patent:

Location-based security for iOS has long been a hobby horse of mine. This patent describes a system that sounds exactly like what I’ve longed for: the ability to have my iOS devices turn on without a passcode while inside my home, but require a passcode or TouchID anywhere else. I'd love to have Touch ID be contextually aware --- am I at home or not? --- and adjust accordingly.
