Enabling continuous or instantaneous identity recognition of a large group of people based on physiological biometric signals obtained from members of a small group of people
First Claim
1. A biometric security system operable to authenticate one or more individuals, said system characterized in that it comprises:
- a) a device operable to obtain one or more physiological signals of each of the one or more individuals, wherein the one or more individuals are initially enrolled in the biometric security system and the one or more individuals are members of a small scale frame work of individuals that were previously identified before the device is employed to currently obtain the one or more physiological signals;
b) a machine learning utility connected to the device, said machine learning utility being operable to biometrically process the one or more physiological signals to determine a variability of physiological signals for a larger population of the one or more individuals based on the one or more physiological signals obtained from the individual members of the small scale frame work, and to identify or verify the identity of each of the one or more individuals, wherein the machine learning utility is trained with recordings of one or more older physiological signals that were previously obtained from the previously identified individuals that are members of the small scale frame work and the larger population of the one or more individuals; and
c) one or more databases connected to the machine learning utility operable to store one or more biometrically processed physiological signals.

Abstract
The present invention is a biometric security system and method operable to authenticate one or more individuals using physiological signals. The method and system may comprise one of the following modes: instantaneous identity recognition (MR); or continuous identity recognition (CIR). The present invention may include a methodology and framework for biometric recognition using physiological signals and may utilize a machine learning utility. The machine learning utility may be presented and adapted to the needs of different application environments which constitute different application frameworks. The present invention may further incorporate a method and system for continuous authentication using physiological signals and a means of estimating relevant parameters.

16. A biometric security method to authenticate one or more individuals, said method characterized in that it comprises the steps of:
-
a) employing a device to receive one or more physiological signals from one or more individuals that are initially enrolled in the biometric security system, wherein the one or more individuals are members of a small scale frame work of individuals that were previously identified before the device is employed to currently receive the one or more physiological signals; b) employing a machine learning utility to pre-process each of the one or more physiological signals to generate a biometrically processed signal and determine a variability of physiological signals for a larger population of the one or more individuals based on the one or more physiological signals obtained from the individual members of the small scale frame work, wherein the machine learning utility is trained with recordings of older one or more physiological signals that were previously received from the previously identified individuals that are members of the small scale frame work and the larger population of the one or more individuals; c) employing the device to extract features from the biometrically processed signal to generate a set of signal features; and d) employing the machine learning utility to classify the set of signal features to identify or verify the identity of each of the one or more individuals. - View Dependent Claims (17, 18, 19, 20, 21, 22)
