1. A biometric authentication system, comprising:
- a biometric sensor comprising a transducer configured to capture biometric information using one or more physical sensing parameters derived from biometric data;
wherein the one or more physical sensing parameters comprising focus, resolution, or contrast parameters of an imaging device;
a calibration component configured to calibrate the transducer during an enrollment procedure such that the one or more physical sensing parameters have respective values corresponding to a single person;
a storage component configured to store template information of only the single person, wherein the template information is captured by the calibrated transducer during the enrollment procedure; and
a processor configured to compare biometric information captured by the calibrated transducer using the one or more physical sensing parameters having respective values corresponding to the single person, during an authentication procedure subsequent to the enrollment procedure, with the stored template information of the single person to determine whether to authenticate a user;
wherein the respective values of the physical sensing parameters remain fixed following the enrollment procedure and are therefore unchanging between the enrollment procedure and the authentication procedure.

Abstract
A biometric authentication system comprises a biometric sensor configured for single user authentication. The biometric sensor can be configured for single user authentication through an enrollment procedure in which one or more sensing parameters are adjusted based on unique characteristics of the user. Thereafter, the user can be authenticated by capturing biometric data using the adjusted sensing parameters and comparing the captured biometric data against stored template data.

9. A biometric authentication system, comprising:
-
a biometric sensor comprising a transducer configured to capture biometric data from a user; an enrollment component configured to receive enrollment biometric data captured by the biometric sensor from a single person, and to generate one or more physical sensing parameters for the biometric sensor based on the received biometric data; wherein the one or more physical sensing parameters comprising focus, resolution, or contrast parameters of an imaging device; a calibration component configured to calibrate the transducer during enrollment by the enrollment component such that the one or more sensing parameters have respective values corresponding to the single person; a storage component configured to store template information of the single person; and an authentication component configured to receive authentication biometric data captured by the biometric sensor using the one or more physical sensing parameters, and to determine whether to authenticate a user by comparing the authentication biometric data with the stored template information of the single person, wherein the respective values of the physical sensing parameters remain fixed following the enrollment and are therefore unchanging between the enrollment and subsequent authentication by the authentication component. - View Dependent Claims (10, 11, 12, 13)

14. A method of operating a biometric authentication system, comprising:
-
calibrating a transducer in a biometric sensor during an enrollment procedure to sense biometric data with one or more physical sensing parameters based on biometric characteristics of only one person, wherein the one or more physical sensing parameters have respective values corresponding to the only one person; wherein the one or more physical sensing parameters comprising focus, resolution, or contrast parameters of an imaging device; storing template information of the only one person, wherein the template information comprises biometric data; and authenticating the only one person by capturing biometric data using the calibrated transducer and comparing the captured biometric data with the stored template information of the only one person; wherein the respective values of the physical sensing parameters remain fixed following the enrollment procedure and are therefore unchanging between the enrollment procedure and the authentication of the only one person. - View Dependent Claims (15, 16, 17, 18, 19)
