Abstract
Biometric iris detection systems are adaptable for control of alarm conditions through the systems scanner or reader by physical actions of a user'"'"'s eye and/or eye lid. An alarm condition can be set in a biometric iris detection system following a predetermined blinking pattern by a user'"'"'s eyelid. An alarm condition also can be set in a biometric iris detection system following closure of a user'"'"'s eyelid for a predetermined time following user identification/acceptance by the system. An alarm condition can following a predetermined movement patter of a user'"'"'s eyeball (e.g., a user looks at a particular area, or areas, within a biometric reader, e.g., upper left, upper right, lower left, lower right, during user identification and acceptance procedures. The embodiments of the present invention can be carried out using biometric iris detection hardware and image processing/control software.

5. A method for assessing a biometric iris detector user'"'"'s eyeball and/or eyelid movements for alarm conditions, the method comprising the steps of:
-
a user begins the biometric iris assessment process at a biometric system;
the biometric system provides background lighting to illuminate the user'"'"'s eye/facial area;
a scanner integrated with the biometric system captures at least one image of the user'"'"'s iris and matches the image with templates stored in a memory that represent the user'"'"'s iris;
simultaneously with iris scanning and matching, the user'"'"'s eyeball and/or eyelid movements are captured by the scanner and evaluated for a predetermined alarm condition;
if a predetermined alarm condition is signaled by the user'"'"'s eyeball and/or eyelid movements, the biometric system triggers an alarm. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 19)

16. A method for assessing a biometric iris detector user'"'"'s eyeball and/or eyelid movements for alarm conditions, the method comprising the steps of:
-
(a) a user begins the biometric iris assessment process at a biometric system;
the biometric system provides background lighting to illuminate the user'"'"'s eye/facial area;
(b) a scanner integrated with the biometric system captures at least one image of the user'"'"'s iris and matches the image with templates stored in a memory that represent the user'"'"'s iris;
(c) simultaneously with iris scanning and matching, the user'"'"'s eyeball and/or eyelid movements are captured by the scanner and evaluated for a predetermined alarm condition;
(d) the biometric system triggers an alarm if a predetermined alarm condition signaled by the user'"'"'s eyeball and/or eyelid movements is captured by the scanner, said predetermined alarm condition including at least one of;
(i) a predetermined blinking pattern by the user'"'"'s eye lid;
(ii) the scanner captures closure of the user'"'"'s eye lid for a predetermined length of time after the user has been identified and/or accepted; and
(iii) the scanner captures predetermined movement pattern by the user'"'"'s eyeball. - View Dependent Claims (17, 18)
