This patent covers a method than can authenticate a person using earphones, thanks to the movement of the mouth. The earphones record the shape of the ear canal during a predefined movement of the mandible and a machine learning algorithm handles the recordings to identify the person. Once the algorithm has identified the person, they can connect to device whenever their earphones are inserted, without touching the device.
Authentication methods are fundamental because they guarantee security and privacy of people’s activities through electronic devices. Biometrics are regularly used for authentication because they combine excellent levels of security and usability. This invention allows people to authenticate to their device through their earphones.
