The paper explores a new method of authentication for smart voice assistants, such as Alexa, Google Home, Siri, etc., called AirBone authentication. This method aims to counter voice spoofing attacks, which are a significant challenge for voice control security. AirBone authentication focuses on head-wearable devices like earbuds and VR headsets, which can continuously monitor the bone-conducted voice in the vibration domain. The authentication process involves two stages – checking time domain consistency and running bone conduction speaker recognition. This method increases security as it can defeat acoustic and cross-domain spoofing samples, and cannot be affected by current acoustic attacks. The article concludes that AirBone authentication is usable, secure, and offers a good user experience.
