1. A method of verifying an identity of a user using a set of earpieces comprising a left earpiece and a right earpiece, the method comprising:
- transducing sound at a speaker of the left earpiece to direct the sound towards a left external auditory canal of the user;
receiving reflected sound at a microphone of the left earpiece, the microphone of the left earpiece positioned to receive reflections from the sound transduced at the speaker of the left earpiece and reflected from the left external auditory canal of the user;
transducing sound at a speaker of the right earpiece to direct the sound towards a right external auditory canal of the user;
receiving reflected sound at a microphone of the right earpiece, the microphone of the right earpiece positioned to receive reflections from the sound transduced at the speaker of the right earpiece and reflected from the right external auditory canal of the user;
processing the reflected sound received at the microphone of the left earpiece to determine a property of the left external auditory canal of the user and processing the reflected sound received at the microphone of the right earpiece to determine a property of the right external auditory canal of the user;
determining if both the property of the left external auditory canal of the user and the property of the right external auditory canal of the user match known properties for a user identity and if so, verifying the identity of the user;
wherein the reflected sound received at the microphone of the left earpiece is conveyed to the processor disposed in the left earpiece over a magnetic inductance linkage between the left earpiece and the right earpiece;
wherein the sound transduced at the speaker of the left earpiece is based on a sound signal generated at the left earpiece which includes one or more randomized components;
wherein the sound transduced at the speaker of the right earpiece is based on a sound signal generated at the left earpiece which includes one or more randomized components and wherein the sound signal is communicated from the left earpiece to the right earpiece over the magnetic inductance linkage between the right earpiece and the left earpiece; and
wherein the sound transduced at the speaker of the left earpiece is different from the sound transduced at the speaker of the right earpiece.

Abstract
A method of verifying an identity of a user using a set of earpieces includes communicating a first sound toward a tympanic membrane of the left ear, communicating a second sound toward a tympanic membrane of the right ear, receiving reflected sounds from an ear canal of the left ear, receiving reflected sounds from an ear canal of the right ear, comparing acoustic properties of the reflected sounds with acoustic properties stored in a memory device, and verifying the identity of the user if the acoustic properties of the reflected sounds match the stored acoustic properties.

7. A method of verifying an identity of a user using a set of earpieces comprising a left earpiece and a right earpiece, the method comprising:
-
transducing sound at a speaker of the left earpiece to direct the sound towards a left external auditory canal of the user; receiving reflected sound at a microphone of the left earpiece, the microphone of the left earpiece positioned to receive reflections from the sound transduced at the speaker of the left earpiece and reflected from the left external auditory canal of the user; transducing sound at a speaker of the right earpiece to direct the sound towards a right external auditory canal of the user; receiving reflected sound at a microphone of the right earpiece, the microphone of the right earpiece positioned to receive reflections from the sound transduced at the speaker of the right earpiece and reflected from the right external auditory canal of the user; processing the reflected sound received at the microphone of the left earpiece to determine a property of the left external auditory canal of the user and processing the reflected sound received at the microphone of the right earpiece to determine a property of the right external auditory canal of the user; determining if both the property of the left external auditory canal of the user and the property of the right external auditory canal of the user match known properties for a user identity and if so, verifying the identity of the user; wherein the reflected sound received at the microphone of the right earpiece is conveyed to the processor disposed in the left earpiece over a magnetic inductance linkage between the left earpiece and the right earpiece; wherein the sound transduced at the speaker of the right earpiece is based on a sound signal generated at the right earpiece which includes one or more randomized components; wherein the sound transduced at the speaker of the left earpiece is based on a sound signal generated at the right earpiece which includes one or more randomized components and wherein the sound signal is communicated from the right earpiece to the left earpiece over the magnetic inductance linkage between the left earpiece and the right earpiece; and wherein the sound transduced at the speaker of the left earpiece is different from the sound transduced at the speaker of the right earpiece. - View Dependent Claims (8, 9, 10, 11, 12, 13)
