Abstract
According to one embodiment of the present invention, a method for coding an iris pattern divides an iris area into a plurality of sectors on the basis of the assumption that a user's pupil and iris are not circular and then can code an iris pattern included in each sector. According to the present invention, an error occurrence frequency can be minimized compared with a case that an iris pattern is coded on the basis of the assumption that a pupil and an iris are circular.
