CONTINUOUS VOICE AUTHENTICATION FOR A MOBILE DEVICE

摘要

Disclosed is an apparatus, system, and method to continuously authenticate a user of a mobile device. The mobile device includes a user interface, a transceiver, a microphone, and processor. The processor continuously samples a users voice from the microphone during a call by obtaining voice snippets on a pre-defined periodic basis or on a random basis. The processor further compares the sampled voice from the microphone to a stored voice to authenticate a valid user, wherein if the sampled voice matches the stored voice for a valid user, functionality of the mobile device continues. On the other hand, if the sampled voice does not match the stored voice for a valid user, functionality of the mobile device is locked.
