Apple has filed a patent for a Touch ID-enabled security feature that would allow users to put their iPhone into “panic mode” by unlocking it with a specific finger. The patent describes a number of potential functions for the feature, such as protecting personal information or just resetting the smartphone entirely, all of which seem to be designed to allow users to protect themselves in the event that they’re forced to use their fingerprint to unlock their iPhone. Such event could be brought about by anything from law enforcement to robbers.
