Abstract

A biometric authentification system and method including a biometric input device structured to detect biometric data of a fingerprint placed on a scanning surface of the biometric input device, a biometric data storage assembly structured to store fingerprint reference data corresponding to an authenticated user, and a biometric comparison assembly structured to identify two minutia points and a connecting pattern therebetween in the fingerprint data, utilizing the minutia points, the connecting pattern and/or pseudo minutia points defined from the connecting pattern as comparison characteristics of the fingerprint which it compares to corresponding characteristics of the stored fingerprint reference data.

Claims

1. A method of analyzing a fingerprint, said method comprising the steps of:

placing a finger on a fingerprint sampling area of a biometric input device;

detecting fingerprint data from the fingerprint sample area;

identifying minutia points in said fingerprint data;

identifying a connecting pattern between at least two of said minutia points; and

utilizing at least a portion of said connecting pattern to define characteristics to distinguish the fingerprint.

2. A method of analyzing a fingerprint as recited in claim 1 wherein said step of placing a finger on a fingerprint sampling area of a biometric input device further comprises placing a finger on a fingerprint sampling area of reduced dimensions.

3. A method of analyzing a fingerprint as recited in claim 2 wherein said step of placing a finger on a fingerprint sampling area of reduced dimensions further comprises placing a finger on a fingerprint sampling area that is smaller than a fingerprint surface area of the finger.

4. A method of analyzing a fingerprint as recited in claim 1 wherein said step of detecting fingerprint data from the fingerprint sample area further comprises the step of detecting a fingerprint image of reduced dimension.

5. A method of analyzing a fingerprint as recited in claim 1 wherein said step of identifying said minutia points in said fingerprint data further comprises identifying at least two adjacent ones of said minutia points.

6. A method of analyzing a fingerprint as recited in claim 5 wherein said step of identifying a connecting pattern between said minutia points further comprises identifying said connecting pattern between said adjacent minutia points.

7. A method of analyzing a fingerprint as recited in claim 1 further comprising a step of separating said connecting pattern into a plurality of pseudo minutia points.

8. A method of analyzing a fingerprint as recited in claim 7 wherein said step of utilizing at least a portion of said connecting pattern as characteristics to distinguish the fingerprint further comprises utilizing said pseudo minutia points as said characteristics to distinguish the fingerprint.

9. A method of analyzing a fingerprint as recited in claim 7 wherein said step of separating said connecting pattern into a plurality of pseudo minutia points further comprises separating said connecting pattern into a number of pseudo minutia points based upon a number of said minutia points identified.

10. A method of analyzing a fingerprint as recited in claim 1 wherein said step of utilizing at least a portion of said connecting pattern as characteristics to distinguish the fingerprint further comprises utilizing said pseudo minutia points to substantially define a contour of said connecting pattern as said characteristics to distinguish the fingerprint.

11. A method of analyzing a fingerprint, said method comprising the steps of:

placing a finger on a fingerprint sampling area of a biometric input device;

detecting fingerprint data from the fingerprint sample area;

identifying minutia points in said fingerprint data;

identifying a connecting pattern between at least adjacent ones of said minutia points;

separating said connecting pattern into a plurality of pseudo minutia points;

utilizing said pseudo minutia points to define characteristics to distinguish the fingerprint.
