Abstract

The invention provides a method for verifying a person'"'"'s identity, which includes obtaining a password and/or random key from a person, and comparing the obtained password and/or random key to a plurality of known passwords and/or random keys to determine a likely identity of the person. The method further includes measuring a specific biometric of the person, the specific biometric comprising a respiratory, cardiac, or other physiologic biometric, and comparing the measured specific biometric to the known specific biometric of the person that is associated with the obtained password and/or random key to verify the likely identity of the person.

Claims

calculating an acceptable variation range for the biometric, wherein the acceptable variation range has upper and lower bounds that differ by a percentage of the measured biometric, and is based on the baseline and the normal deviation for the biometric across a population sample of people;

storing the acceptable variation range in a memory;

obtaining a password or key from a person to be verified;

comparing the obtained password or key to a plurality of known passwords or keys to determine a likely identity of the person to be verified, wherein each of the plurality of known passwords or keys are associated with a specific person;

obtaining a measurement of the biometric from the person to be verified and setting a value for the biometric for the person to be verified; and

comparing the value of the biometric for the person to be verified to a stored acceptable variation range of a specific person associated with the obtained password or key to verify the likely identity of the person to be verified.

2. The method of claim 1, wherein the respiratory biometric comprises a respiratory rate, a minute ventilation, a tidal volume, an inspiratory flow rate, an expiratory flow rate, a presence of cough, or a presence of apnea or hypoapnea.

3. The method of claim 1, wherein the girth is measured by inductive plethysmography.

4. The method of claim 1, wherein measuring the respiratory biometric comprises:

instructing the person whose identity is known and the person to be verified to perform one or more maneuvers; and

measuring at least one respiratory pattern exhibited by the person whose identity is known and the person to be verified during performance of the maneuvers, wherein the baseline respiratory biometric for the person whose identity is known and the set value for the respiratory biometric for the person to be verified comprise at least one measured respiratory pattern.

5. The method of claim 4, wherein the at least one respiratory pattern is measured over a period time during the performance of the maneuvers.

6. The method of claim 4, wherein at least one maneuver comprises performing a predetermined sequence of breaths.

7. The method of claim 4, wherein at least one maneuver comprises performing a predetermined sequence of physical movements.

8. The method of claim 1, wherein the biometric comprises a plurality of physiological parameters.

12. The method of claim 8, wherein the plurality of physiological parameters includes at least one of the following:

a cardiac parameter, a posture/activity parameter, a temperature parameter, an EEG parameter, an EOG parameter, EMG parameter, a vocal parameter, and a gait parameter.

13. The method of claim 1, wherein the person whose identity is known and the person to be verified are the same person.

9. A method for verifying a person'"'"'s identity, comprising:

measuring a biometric of a person whose identity is known, wherein the biometric comprises a respiratory biometric, and setting a baseline for the biometric based on the measurement, wherein the thoracic or abdominal girth of the person is measured;
