SYSTEM AND METHOD FOR LOW OVERHEAD VOICE AUTHENTICATION
First Claim
1. A method of generating a voice identification in a time domain comprising:
- identifying in a voice signal an initial rise time portion, an initial fall time portion, a second rise time portion, a second fall time portion and a final oscillation time portion, said time portions forming a period of said voice signal;
measuring the time value of each of said time portions;
digitizing the time value of each of said time portions into a first predetermined number of bits; and
,concatenating said bits to form said voice identification.

Abstract
A system and method are provided to authenticate a voice in a frequency domain. A voice in the time domain is transformed to a signal in the frequency domain. The first harmonic is set to a predetermined frequency and the other harmonic components are equalized. Similarly, the amplitude of the first harmonic is set to a predetermined amplitude, and the harmonic components are also equalized. The voice signal is then filtered. The amplitudes of each of the harmonic components are then digitized into bits to form at least part of a voice ID. In another system and method, a voice is authenticated in a time domain. The initial rise time, initial fall time, second rise time, second fall time and final oscillation time are digitized into bits to form at least part of a voice ID. The voice IDs are used to authenticate a user'"'"'s voice.
