INDIVIDUAL IDENTIFICATION DEVICE, AND IDENTIFICATION THRESHOLD SETTING METHOD

摘要

Provided is an individual identification device including: a biometric information storage unit; a biometric information acquisition unit; an identification unit which calculates a similarity of the biometric information on the subject and the registrant and performs identification of the subject according to whether or not the calculated similarity is equal to or higher than an identification threshold; an identification result storage unit which stores identification result information constituted by the calculated similarity and a correct identification result; and a threshold setting unit which sets the identification threshold such that at least either one of a false rejection rate and a false acceptance rate fulfils a predetermined condition in the identification result information stored in the identification result storage unit.
