Patent Images
1. A method of authenticating a user comprising:
- storing a reference biometric data of the user;
performing initial authentication by obtaining biometric data of the user and comparing the obtained biometric data with the reference biometric data;
storing the obtained biometric data upon successful initial authentication;
performing second and subsequent authentication by obtaining biometric data of the user and comparing instantaneously obtained biometric data with the reference biometric data and the stored obtained biometric data; and
updating the stored obtained biometric data each time the second or the subsequent authentication is successful.
