User privacy is a critical issue for Apple and the company has previously gone to admirable level to prove this thing. With iOS 11, the Apple has introduced a new feature that allows users to quickly disable Touch ID by simply tapping the power button five times, in situations where they can be physically forced to unlock their device using their fingerprint.
As pointed out in a report by The Verge, some users have discovered that when you quickly tap the power button five times on a device that is currently running iOS 11 public beta, the option to call emergency call numbers is presented as usual but the system automatically disables Touch ID as well. This means that the users are required to enter the passcode before they can start using Touch ID again. It’s being called a ‘cop button’, after cases where Michigan police 3D-printed a fingerprint to get access to a locked iPhone, The Verge notes.
For a better perspective, the system used to earlier disable the Touch ID temporarily when an iOS device restarted or when you didn’t place the finger effectively on the device few times continuously. You already have the choice to disable the Touch ID completely from the system settings but doing this can make things inconvenient for the user. The new feature guarantees that the Touch ID is temporarily disabled only when a user decides to disable it in emergency situations. As it requires five quick taps, it is very rare that users can accidentally disable the Touch ID as well.
Apple has been vigorously tipped to introduce 3D facial recognition feature in its upcoming iPhone models this year and if this ends up being valid, the new feature will furnish users with extra privacy regardless of the possibility that they are physically constrained by somebody to unlock the device.
