Methods and systems for authenticating users with captured palm biometric data
First Claim
1. A method of authenticating users comprising:
- capturing biometric authentication data of a user and processing the captured biometric data into an image with a communications device, and communicating the captured biometric data image to an authentication system;
determining an authentication region of interest of the captured biometric data image and a gray scale image from the captured biometric data image;
applying a transformation against the gray scale image to align the gray scale image with an enrollment gray scale image generated during enrollment of the user;
generating an authentication mask;
applying the transformation against the authentication mask to align the authentication mask with an enrollment mask generated during enrollment of the user in the authentication system;
generating a biometric template from the aligned gray scale image;
comparing the authentication mask against the enrollment mask to determine a region common to both; and
conducting a biometric authentication matching transaction with biometric data, included in the biometric template, that is within the common region.

Abstract
A method of authenticating users is provided that includes capturing biometric authentication data of a user and processing the captured biometric data into an image. Moreover, the method includes determining a region of interest of the image and a gray scale image from the image, determining an optimum transformation parameter set within the region of interest, and aligning the gray scale image with an enrollment gray scale image generated during enrollment of the user using results of the optimum transformation parameter set determination. Furthermore, the method includes extracting biometric feature data from the gray scale image and verifying an identity of the user with extracted biometric feature data included in a region of agreement.

-
capturing biometric authentication data of a user and processing the captured biometric data into an image with a communications device, and communicating the captured biometric data image to an authentication system; determining an authentication region of interest of the captured biometric data image and a gray scale image from the captured biometric data image; applying a transformation against the gray scale image to align the gray scale image with an enrollment gray scale image generated during enrollment of the user; generating an authentication mask; applying the transformation against the authentication mask to align the authentication mask with an enrollment mask generated during enrollment of the user in the authentication system; generating a biometric template from the aligned gray scale image; comparing the authentication mask against the enrollment mask to determine a region common to both; and conducting a biometric authentication matching transaction with biometric data, included in the biometric template, that is within the common region. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A system for authenticating a user comprising:
-
an authentication system including an authentication database, said authentication system being configured to communicate with devices, to generate and store an enrollment mask for each user enrolled therein, to generate and store an enrollment template data record for each user enrolled therein, to generate authentication masks, and to store within said authentication database at least authentication data for a plurality of users; and a device configured to communicate with at least said authentication system and to capture authentication data, said authentication system being further configured to determine an authentication region of interest and a gray scale image of authentication data captured by said device, apply a transformation against the gray scale image to align the gray scale image with an enrollment gray scale image generated during enrollment of the user; apply the transformation against the authentication mask to align the authentication mask with an enrollment mask generated during enrollment of the user in said authentication system; generate a biometric template from biometric data extracted from the aligned gray scale image; compare the authentication mask against the enrollment mask to determine a region common to both; and conduct a biometric authentication matching transaction with the biometric data included in the biometric template that is within the common region. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A computer program recorded on a non-transitory computer-readable recording medium included in an authentication computer system for authenticating a user, the computer program for causing the authentication computer system to execute at least the following:
-
communicating a captured biometric authentication data image from a device to an authentication system; determining an authentication region of interest of the image and a gray scale image from the image; applying a transformation against the gray scale image to align the gray scale image with an enrollment gray scale image generated during enrollment of the user; generating an authentication mask; applying the transformation against the authentication mask to align the authentication mask with an enrollment mask generated during enrollment of the user in the authentication system; extracting biometric data from the aligned gray scale image and generating a biometric template from the extracted biometric data; comparing the authentication mask against the enrollment mask to determine a region common to both; and comparing biometric data included in the biometric template that is within the common region against biometric data included in an enrollment template data record that is within the common region. - View Dependent Claims (17)
