Abstract

In an authentication input apparatus, an input unit is a surface for inputting data of an input device such as a pressure sensitive sensor. The input device may also be an optical sensor such as a CCD. The input unit receives from a user input of a fingerprint, a signature or the like. In inputting the signature, the input unit functions as a tablet for inputting signatures utilizing a stylus equipment or the like. In inputting the fingerprint or the signature the user specifies the type of authentication information to be inputted by pressing a fingerprint selection button or a signature selection button. Fingerprint data are obtained by the input device when the user puts the finger on the input unit after pressing the fingerprint selection button. Signature data are obtained by the input device when the user signs on the input unit 10 after pressing the signature selection button.

Claims

1. An authentication apparatus, comprising:

a single input device to which biometric data are inputted as information for authentication; and

a detection unit which detects a type of the information inputted to the single input device among precedently assumed two or more types,

wherein the biometric data of two or more types are sequentially inputted to the single input device.

2. An authentication apparatus according to claim 1, further comprising a display unit which issues warning when the detection unit detects that the type of the inputted information for the authentication is not included in the precedently assumed two or more types.

3. An authentication apparatus according to claim 1, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

4. An authentication apparatus according to claim 2, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

5. An authentication apparatus, comprising a single input device to which biometric data and non-biometric data are inputted as information for authentication, wherein the biometric data and the non-biometric data are sequentially inputted to the single input device.

6. An authentication apparatus according to claim 5, further comprising an authentication type selection unit for selectively specifying a type of the information for the authentication, wherein the type of the information for the authentication to be inputted is specified by the authentication type selection unit when the information for the authentication is inputted to the single input device.

7. An authentication apparatus according to claim 5, further comprising a detection unit which detects a type of the information for the authentication inputted to the single input device among precedently assumed two or more types.

8. An authentication apparatus according to claim 7, further comprising a display unit which issues warning when the detection unit detects that the type of the inputted information for the authentication is not included in the precedently assumed two or more types.

9. An authentication apparatus according to claim 6, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being specified by the authentication type selection unit.

10. An authentication apparatus according to claim 7, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

11. An authentication apparatus according to claim 8, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

12. An authentication apparatus, comprising a single input device of an input-by-touch type to which biometric data and non-biometric data are inputted as information for authentication, wherein the biometric data and the non-biometric data are sequentially inputted to the single input device.

13. An authentication apparatus according to claim 12, further comprising an authentication type selection unit for selectively specifying a type of the information for the authentication, wherein the type of the information for the authentication to be inputted is specified by the authentication type selection unit when the information for the authentication is inputted to the single input device of the input-by-touch type.

14. An authentication apparatus according to claim 12, further comprising a detection unit which detects a type of the information for the authentication inputted to the single input device of the input-by-touch type among precedently assumed two or more types.

15. An authentication apparatus according to claim 14, further comprising a display unit which issues warning when the detection unit detects that the type of the inputted information for the authentication is not included in the precedently assumed two or more types.

16. An authentication apparatus according to claim 13, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being specified by the authentication type selection unit.

17. An authentication apparatus according to claim 14, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

18. An authentication apparatus according to claim 15, further comprising an authentication processing unit which carries out the authentication after selecting feature extraction processing suitable for the type of the inputted information for the authentication, the type being detected by the detection unit.

19. An authentication method, comprising:

receiving sequential input of information for authentication of two or more types to a single input device of an input-by-touch type; and

receiving from a user information specifying a type of the information for the authentication, when the information for the authentication is inputted.

20. An authentication method, comprising:

receiving sequential input of information for authentication of two or more types to a single input device of an input-by-touch type; and

detecting a type of the information for the authentication among precedently assumed two or more types.
