Apple has patented a new technology to more discreetly call emergency services by simply touching the iPhone screen, aimed at helping users evade potential attackers, according to a report by CNBC.

The filing explains that the iPhone would analyze a number of criteria such as a certain sequence of fingers, the level of force, a gesture (pinching or swiping), or a particular cadence of taps to the screen.

Once the user activates the “panic command”, the device sends his or her location to responders. The technology also enables users to livestream audio or video from the phone, as well as activate other types of mobile command.

With Apple’s newly patented technology, if an attacker requires the user to unlock or use the phone, the user would appear to be following their attacker’s orders while discreetly calling 911.
