Method and apparatus for processing biometric information

摘要

A biometric-information processing apparatus and method including storing sample biometric information of a user each time biometric authentication processing for verifying sample biometric information of a user against enrolled biometric information registered in a first storage unit succeeds, where the user's sample biometric information is stored in a second storage unit, and selecting an update-candidate biometric information for updating the user's enrolled biometric information from the user's sample biometric information stored in the second storage unit, based on a result of verification of multiple pieces of the user's sample biometric information stored in the second storage unit against enrolled biometric information of other users.

主权项

1. A biometric-information processing apparatus, comprising:
a memory; and a processor coupled to the memory and configured to execute a process including:
storing sample biometric information of a user into a second storage unit each time verification of sample biometric information of the user compared against enrolled biometric information registered in a first storage unit succeeds; andupdating an update candidate among multiple pieces of the user's sample biometric information stored in the second storage unit, where the update candidate is selected as having a lowest false accept rate when compared against enrolled biometric information of other users.
