User authentication method and apparatus
First Claim
Patent Images
1. A user authentication method that authenticates a user based on a password input by the user and the user'"'"'s biometrics information, the user authentication method comprising:
- determining whether a password has been input;
setting a first threshold value if the input password matches with a registered password and setting a second threshold value if the input password does not match with the registered password; and
determining whether to authenticate the user based on a comparison of the user'"'"'s biometrics information with registered biometrics information and the first or second threshold value.

Abstract
A user authentication method and apparatus including determining whether a password has been input; setting a first threshold value if the input password matches with a registered password and setting a second threshold value if the input password does not match with the registered password; and determining whether to authenticate the user or not based on a comparison of the user'"'"'s biometrics information with registered biometrics information and the first or second threshold value.

11. A user authentication apparatus that authenticates a user based on a password input by the user and the user'"'"'s biometrics information, the user authentication apparatus comprising:
-
a password input unit which determines whether a password has been input; a storage unit which stores a registered password and registered biometrics information; a threshold value setting unit which sets a first threshold value if the input password matches with a registered password and sets a second threshold value if the input password does not match with the registered password; and a biometrics unit which obtains biometrics information from the user outside, determines how much the obtained biometrics information matches with the registered biometrics information, and authenticates a user if the extent to which the obtained biometrics information matches with the registered biometrics information is larger than the first or second threshold value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

24. A user authentication method, comprising:
adjusting a threshold level of a biometrics device which reads a user'"'"'s biometric information based on a password input by a user, wherein the threshold level is broadened when the user inputs a valid password to increase the possibility of the user being authenticated by the biometrics device, and the threshold level is narrowed when the user inputs an invalid password to decrease the possibility of the user being authenticated by the biometrics device. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
