Abstract: An iris biometric image is analyzed to determine the apparent angle of the eye in the image, relative to an arbitrarily selected reference axis. The angle information is stored for use by the matching engine and/or the image data is modified to normalize the angle relative to the reference axis. In this manner, rotationally normalized data may be stored to facilitate future comparisons, and images obtained in real time may be used for iris identification in a matching engine that automatically compensates for angular variation.
Abstract: An automated method of performing various processes and procedures includes central and/or distributed iris identification database servers that can be accessed by various stations. Each station may be equipped with a handheld staff-operated iris camera and software that can query the server to determine whether an iris image captured by the iris camera matches a person enrolled in the system. The station takes selective action depending on the identification of the person. In disclosed medical applications, the station may validate insurance coverage, locate and display a medical record, identify a procedure to be performed, verify medication to be administered, permit entry of additional information, history, diagnoses, vital signs, etc. into the patient's record, and for staff members may permit access to a secure area, permit access to computer functions, provide access to narcotics and other pharmaceuticals, enable activation of secured and potentially dangerous equipment, and other functions.
