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.
