Abstract: A biometric authentication method includes determining a first similarity between first biometric data and first registration data; determining a second similarity between second biometric data and second registration data; performing authentication based on the first similarity and the second similarity; and updating the first registration data based on the first biometric data in response to the first similarity being greater than an authentication reference value corresponding to the first similarity and the second similarity being greater than an update reference value corresponding to the second similarity.
