System and method for determining an in-ear acoustic response for confirming the identity of a user
First Claim
1. A system for confirming the identity of a user comprising:
- an internal speaker, positioned within the ear of the user, adapted for producing a signal having one or more frequencies;
an internal microphone, positioned within the ear of the user, adapted for detecting a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections;
a storage unit, which includes a prestored hearing profile, which is adapted for predicting an expected signal, resulting from a produced signal having one or more frequencies; and
a signal processing unit, coupled to the internal speaker, the internal microphone, and the storage unit, the signal processing unit including;
a selection unit for selecting one or more frequencies to be produced, wherein the frequencies produced by the internal speaker include a dynamically selected set of frequencies determined proximate the time of measurement;
a comparison unit for comparing the resulting signal with a predetermined expected signal; and
a determination unit for determining if the resulting signal detected by the internal microphone matches the corresponding predetermined expected signal.

Abstract
A system and method is provided for confirming the identity of a user, where the confirmation is made using biometric data. The system includes an internal speaker having an audio port, which is positioned within the ear of the user, and is adapted for producing a signal having one or more frequencies. The system further includes an internal microphone having an audio port, which is positioned within the ear of the user, and is adapted for detecting a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections. A determination is then made as to whether the resulting signal detected by the internal microphone matches the corresponding predetermined expected signal, based upon a prestored hearing profile.

13. A system for confirming the identity of a user comprising:
-
an internal speaker, positioned within the ear of the user, adapted for producing a signal having one or more frequencies; an internal microphone, positioned within the ear of the user, adapted for detecting a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections; a storage unit, which includes a prestored hearing profile, which is adapted for predicting an expected signal, resulting from a produced signal having one or more frequencies; and a signal processing unit, coupled to the internal speaker, the internal microphone, and the storage unit, the signal processing unit including; a selection unit for selecting one or more frequencies to be produced; a comparison unit for comparing the resulting signal with a predetermined expected signal; and a determination unit for determining if the resulting signal detected by the internal microphone matches the corresponding predetermined expected signal; and wherein the internal microphone and internal speaker are incorporated as part of an earpiece; wherein the earpiece includes an earbud, which fits at least partially within an ear canal of the user; wherein the earbud includes a housing having an external surface which provides a seal against the inner wall of the ear canal, when at least a portion of the earbud is firmly placed within the ear canal of the user; wherein the external surface includes one or more pressure sensors for detecting the integrity of the seal against the inner wall of the ear canal; and wherein the pressure sensors are adapted to detect the geometry of the ear of the user.

14. A method for confirming the identity of a user using an audio receiving system including an internal microphone and an internal speaker proximate an ear of a user, said method comprising:
-
selecting one or more frequencies; producing a signal by the internal speaker having the one or more frequencies; receiving a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections; comparing the received resulting signal with a predetermined expected signal; and determining if a substantial match exists between the received resulting signal and the predetermined expected signal; and wherein the frequencies produced by the internal speaker include a dynamically selected set of frequencies determined proximate the time of measurement. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
