Methods and systems for capturing biometric data
First Claim
1. A method of capturing biometric data comprising:
- capturing desired biometric data from an individual with a device after approximately aligning an outline image with a desired biometric data image on the device;
generating an authentication gray scale image from the captured biometric data and aligning the authentication gray scale image with an enrollment gray scale image; and
verifying the identity of the individual.

Abstract
A method of capturing biometric data is provided that includes activating a security application in a device. The security application is activated by an operator of the device and is configured to cause the device to display an outline image. Moreover, the method includes displaying the outline image in a stationary position on a display of the device, positioning desired biometric data proximate the device such that the desired biometric data appears as a biometric image on the device display, and monitoring the outline and biometric images shown on the device display. Furthermore, the method includes positioning the device and the desired biometric data to better align the outline and biometric images when the outline and biometric images do not align and capturing the desired biometric data from an individual after approximately aligning the outline image with the biometric image.

7. A computer system for capturing biometric data comprising:
-
an authentication system including an authentication database, said authentication system being configured to at least communicate with devices, store biometric data in said authentication data base, and generate outline images from biometric data captured from individuals; and a device including at least a display, said device being configured to communicate with at least said authentication system, display an outline image and an image of desired biometric data on said device display during authentication of an individual, and capture biometric data from the individual when the image of the desired biometric data aligns approximately with the outline image on the device display, said authentication system being further configured to generate an authentication gray scale image from the captured biometric data, generate an enrollment gray scale image from biometric data captured during enrollment in said authentication system, and align the authentication gray scale image with the enrollment gray scale image to determine a region of agreement. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program recorded on a non-transitory computer-readable recording medium included in an authentication computer system for enabling authentication of individuals, the computer program being comprised of instructions, which when read and executed by the authentication computer system, cause the authentication computer system to perform at least the following operations:
-
display an outline image of biometric data on a display screen; display biometric data desired to be captured as a biometric image on the display screen; capture the desired biometric data when the biometric image is within a tolerance of the outline image; generate an authentication region of interest of the captured biometric data, and generating an authentication gray scale image and an authentication mask from the captured biometric data; align the authentication gray scale image with an enrollment gray scale image generated during enrollment in an authentication computer system; align the authentication mask with an enrollment mask; compare the aligned authentication and enrollment masks to determine a region of agreement; and conduct a biometric verification matching transaction with biometric feature data extracted from the aligned authentication gray scale image that is within the region of agreement. - View Dependent Claims (14, 15, 16, 17)
