To provide an individual identifying device with which collation can be highly accurately performed for a long time even when iris data are registered just after birth.
A boundary determining part 1 determines the boundary of the pupil and the iris of an ophthalmic image. A sub-boundary determining part 2 calculates a plurality of sub-boundaries on the basis of the boundary determined by the boundary determining part 1. Corresponding to the boundary and the sub-boundaries, an analytic part 3 segments a plurality of iris images and encodes these iris images. A registered data storage part 5 stores registered data as previously registered dictionary data. An identification part 4 identifies an individual by comparing the plurality of codes analyzed by the analytic part 3 with the registered data in the registered data storage part 5.
