METHOD AND APPARATUS FOR AUTHENTICATING USER BY USING INFORMATION PROCESSING DEVICE

摘要

A method and apparatus for authenticating a user is disclosed that includes measuring biometric information of the user to create biometric measurement information, determining whether a private key included in a user authentication request signal matches a private key issued in advance to the user, comparing pre-set biometric authentication information for the user with the biometric measurement information, calculating a matching ratio when a match is detected, authenticating the user having provided the biometric information as an authorized user based on a result of comparison of the calculated matching ratio with a pre-determined biometric authentication threshold value, and providing an updated private key to the information processing device based on a result of comparison of the calculated matching ratio with a pre-determined updated threshold value.

1. A method for authenticating a user, the method comprising:
obtaining a user authentication request signal including a private key from an information processing device; measuring biometric information of the user and creating biometric measurement information based on the measurement; detecting whether the private key included in the user authentication request signal matches a private key issued in advance to the user; in response to detecting a match, comparing pre-set biometric authentication information for the user with the biometric measurement information and calculating a matching ratio; comparing the calculated matching ratio with a pre-determined biometric authentication threshold value; authenticating the user having provided the biometric information as an authorized user based on the comparison of the calculated matching ratio with the pre-determined biometric authentication threshold value; and comparing the calculated matching ratio with a pre-determined updated threshold value; and providing an updated private key to the information processing device based on a result of the comparison of the calculated matching ratio with the pre-determined updated threshold value.
