1. A method of authenticating a measure of sleepiness in a person, the method comprising:
- measuring a person'"'"'s sleepiness; and
performing an authentication step substantially simultaneously with measuring a 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.

15. An apparatus for authenticating sleepiness measurements, comprising:
-
a camera structured to scan an eye of a person;
a frame constructed and arranged to position the camera in front of the eye of the person in use;
a hood structured to shield the eye from illumination by an external source of light in use; and
at least one light structured to illuminate the eye of the person at at least one predetermined level of illumination in use, wherein the camera is structured to provide an image of an iris of the eye of the person in a form suitable for calculating an identifying code of the iris. - View Dependent Claims (16, 17)

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;
identifying first features of the eye from the first scan;
calculating a first code based on the first features identified from the first scan;
measuring a first pupil size of the eye from the first scan;
performing a second scan of the eye;
identifying second features of the eye from the second scan;
calculating a second code based on the second features from the second scan;
measuring a second pupil size of the eye from the second scan; and
comparing the first and second codes to determine whether the eye used in the first and second scans are the same. - View Dependent Claims (19, 20, 21)

22. A method of authenticating a measure of sleepiness in a person, the method comprising:
-
performing pupillometry on an eye of the person to determine an index of sleepiness;
performing iris scanning on the eye of the person to determine a code for authentication; and
certifying that the index of sleepiness is matched with the code for authentication. - View Dependent Claims (23)
