Abstract
Techniques are provided herein for identifying the user of audio earbuds. In particular, a wearer's head filters an audio signal, and the audio filtering capabilities of a user's head are used as a biometric feature. One earbud can be used as an audio emitter and the other earbud as an audio receiver. A broadband sound can be generated by the speaker in one earbud and received at the microphone of the other earbud. The received sound is filtered by the user's head and the head characterization of the received filtered sound can be used to identify the user. In particular, the material properties of the user's head change the signal, such that the received signal at the microphone of the other earbud is different from the transmitted signal. The differences are unique to the user's head due to physiological variances among people, and can be used to identify the user.
