Apple AirPods could soon identify you based on the shape of your EAR CANAL, patent suggests

Apple's AirPods could soon verify a user's identity based on the inside of their ear, which could stop them from being used by thieves. The tech giant has filed a patent for an in-ear biometric device that uses ultrasonic signals reflected against the walls of a user's ear canal. Such technology would prevent lost AirPods from being used by anyone other than the owner if they get misplaced or stolen. Currently, AirPods and other headphones pose a security risk because anyone can wear them to give Siri commands or even access private information. The product could'determine whether [the] users is an authorised user', although the patent doesn't specifically mention AirPods Biometrics are any metrics related to human features.
