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.

Claims

1. A method for authenticating users comprising:

generating, by a processor, an authentication image from biometric data, the biometric data captured from a user with a device after an outline image displayed by the device is approximately aligned with an image of the biometric data displayed by the device;

aligning the authentication image with an enrollment image; and

verifying the identity of the user.

2. A method in accordance with claim 1, said verifying step comprising:

generating an authentication mask from the captured biometric data;

aligning the authentication mask with a user enrollment mask;

comparing the masks to determine a common region; and

comparing authentication image biometric data within the common region against user enrollment image biometric data within the common region.

3. A method in accordance with claim 2, said comparing biometric data step comprising:

generating a matching score for the comparison;

comparing the matching score against a threshold score; and

conducting a transaction desired to be conducted by the user when the matching score is at least equal to the threshold score.

4. A method in accordance with claim 2, said comparing the masks step comprising:

determining a first authentication area of valid biometric data and a second authentication area of invalid biometric data included in the authentication mask;

aligning the authentication mask with a user enrollment mask, the user enrollment mask including a first enrollment area of valid biometric data and a second enrollment area of invalid biometric data; and

comparing the authentication mask against the enrollment mask and determining common regions of valid biometric data as the common region.

5. A method in accordance with claim 1, said aligning step comprising:

calculating a transformation; and

applying the transformation against the authentication image.

6. A method for authenticating users comprising:

generating, by a processor, an authentication image from biometric data, the biometric data captured by a device from a user after an outline image displayed by the device is approximately aligned with an image of the biometric data displayed by the device;

aligning the authentication image with an enrolment image;

generating a biometric template from the aligned authentication image; and

comparing the generated biometric template against a corresponding enrollment biometric template to verify the user.

7. A method in accordance with claim 6, said aligning step comprising:

generating an authentication mask, the authentication mask including a first authentication area of valid biometric data and a second authentication area of invalid biometric data;

aligning the authentication mask with a user enrollment mask, the user enrollment mask including a first enrollment area of valid biometric data and a second enrollment area of invalid biometric data; and

comparing the authentication mask against the enrollment mask and determining common regions of valid biometric data to be a common region.

8. A method in accordance with claim 6, said comparing step comprising

determining a common region;

and

comparing generated biometric template feature data within the common region against enrollment biometric template feature data within the common region.

9. A method in accordance with claim 6 further comprising conducting a transaction desired to be conducted by the user after the identity of the user is verified.

10. A method in accordance with claim 6, said aligning step further comprising:

determining an optimum rotation angle, an optimum scale factor and coordinates of an optimum area to be an optimum transformation parameter set;

calculating a transformation using the optimum transformation parameter set; and

applying the transformation against the authentication image.
