1. An iris recognition method comprising: obtaining binary image data by receiving eye image data and filtering the received eye image data using a predetermined threshold value; searching candidate center search regions for finding a pupil center using profile information of rows and columns of the binarized image; detecting a pupil boundary and a center point by performing a mask operation using 8 pupil boundary mask templates for each of concentric circles formed of points in the searched candidate center search regions as candidate pupil centers and different radiuses, wherein each pupil boundary mask template is formed of a 15×15 formation; and detecting an iris boundary region by performing a masking operation using 6 iris boundary mask templates corresponding to 6 locations for concentric circles formed of the pupil center as an origin and different radiuses.
