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 eyelid. 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.
