Abstract: The embodiments disclosed herein relate to a biometric information registration apparatus and method using an artificial neural network. According to an embodiment, there are disclosed a biometric information registration apparatus and method that register biometric information by deriving converted information and a biometric information template based on an artificial neural network formed by successively connecting an encoding network for extracting security information and a feature point extraction network for extracting feature points to each other and renew the biometric information template using the converted information when updating the artificial neural network.

Abstract: A method for performing biometric recognition in a system in which biometric information is distributed and stored in a plurality of databases includes extracting biometric information of a user, generating a plurality of biometric information segments by dividing the extracted biometric information, calculating distances between pre-stored biometric information template segments for each of the plurality of databases and a corresponding one of the plurality of biometric information segments, and detecting a biometric information template matching the biometric information by using the calculated distances.
