Recent Apple patent filing speaks of stealth biometric security on iPhone

via engadget.com
No one probably believes me but I jokingly mentioned this last week that Apple should just use biometrics for unlocking your iPhone instead of requiring a passcode.
I also find this diagram interesting because it's the first Apple artifact I've seen that labels the application manger the "Springboard". I've heard people call it this but until now, I've only seen Apple refer to this as the Home Screen.
