Abstract
An electronic device includes at least one processor connected with a biometric sensor and memory, and configured to perform biometric authentication using a first matching algorithm and a first template DB, install a second matching algorithm and a second template DB and set the second template DB to an inactive state, determine whether a predetermined template registration condition is met when biometric authentication using the first matching algorithm and the first template DB is successful, generate a template including input biometric information of the successful biometric authentication and register the template in the second template DB in the inactive state in case that the template registration condition is met, set the second template DB to an active state in case that the second template DB meets a predetermined template activation condition, and perform the biometric authentication using the second matching algorithm and the second template DB in the active state.
