摘要

PROBLEM TO BE SOLVED: To provide a re-registration method of biometric data, a re-registration device of biometric data and a re-registration program of biometric data which can update registered biometric data with proper data.;SOLUTION: A re-registration method of biometric data calculates a first matching degree between registered biometric data stored in a storage unit and collation data acquired at authentication via a sensor, calculates a second matching degree between provisionally-registered biometric data stored in the storage unit and the collation data, and based on a relation between the second matching degree and the first matching degree, replaces the registered biometric data stored in the storage unit with the provisionally-registered biometric data.;COPYRIGHT: (C)2012,JPO&INPIT
