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 pointes in the searched candidate center search regions as candidate pupil centers and different radiuses; 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.
