1. A method of authenticating a measure of sleepiness in a person, the method comprising:
- measuring the person'"'"'s sleepiness; and
performing an authentication step to determine the person'"'"'s identity substantially simultaneously with measuring the person'"'"'s sleepiness, wherein the person'"'"'s sleepiness and the authentication step are performed on substantially the same physical attribute of the person.

Abstract
A method and apparatus are provided for authenticating a measure of sleepiness in a person in which a measure of the person'"'"'s sleepiness and an authentication step are performed substantially simultaneously on substantially the same physical attribute of the person. In one form, an eye of a person is scanned under infrared light and a unique identifying code is calculated from the iris as an authentication step. In one form, a measure of the person'"'"'s sleepiness is determined from changes in the pupil size with time.

7. A method of authenticating a measure of sleepiness in a person, the method comprising:
- illuminating an eye of the person by an infrared light;
measuring the person'"'"'s sleepiness by the eye; and
performing an authentication step by the eye to verify the identity of the person whose sleepiness is being tested.

8. An apparatus for authenticating sleepiness measurements, comprising:
- a camera; and
a computer having a sleepiness measuring software module to measure sleepiness of a person via the person'"'"'s eye and an eye authentication software module to verify the identity of the person whose sleepiness is being measured, wherein the person'"'"'s sleepiness is measured and authentication is verified substantially simultaneously. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of authenticating a measure of sleepiness on an eye of a person, the method comprising:
-
performing a first scan of the eye; calculating a first code based on the first scan; performing a second scan of the eye; calculating a second code based on the second scan; and comparing the first and second codes to determine whether the eye used in the first and second scans is the same.

16. A method of authenticating a measure of sleepiness on an eye of a person, the method comprising:
-
performing a first scan of the eye; calculating a first code based on the first scan; performing a second scan of the eye; calculating a second code based on the second scan; comparing the first and second codes to determine whether the eye used in the first and second scans are the same; and calculating a rate of change of pupil size between the first and second scans if the same eye has been confirmed to be used in both scans.

17. A method of authenticating a measure of sleepiness on an eye of a person, the method comprising:
-
performing a first scan of the eye; calculating a first code based on the first scan; performing a second scan of the eye; calculating a second code based on the second scan; comparing the first and second codes to determine whether the eye used in the first and second scans are the same; and identifying an iris of the person for each of the first and second scans.

18. A method of authenticating a measure of sleepiness on an eye of a person, the method comprising:
-
performing a first scan of the eye; calculating a first code based on the first scan; performing a second scan of the eye; calculating a second code based on the second scan; comparing the first and second codes to determine whether the eye used in the first and second scans are the same; and determining a power of low frequency oscillations in pupil size.

19. A method of authenticating a person and detecting a medical condition, wherein the method comprises:
-
scanning an eye of the person, measuring data of at least one physical attribute of the eye, and simultaneously comparing said data with predetermined values to authenticate the identity of the person; and detecting the presence of a medical condition based on the measuring of the scanned data. - View Dependent Claims (20, 21, 22, 23)
