Fingerprint check to reduce check fraud
First Claim
Patent Images
1. A method comprising:
- receiving a digital image of a surface of a check, wherein a fingerprint is impressed on the surface of the check, the digital image including a fingerprint image;
using the fingerprint image to determine an initial match score for the fingerprint;
calculating a fingerprint image quality metric of the fingerprint image, the fingerprint image quality metric being a number based on at least one or more changes made to the fingerprint image;
adjusting the initial match score based on the fingerprint image quality metric to create an adjusted match score; and
presenting an alert based on the adjusted match score.

Abstract
A digital image of a surface of a check is received. A check scanning device captures the digital image as the check moves through the check scanning device. A fingerprint is impressed on the surface of the check. A computing system uses the digital image to determine an initial match score for the fingerprint image and an image quality metric to create an adjusted match score. An alert is presented based on the adjusted match score.

14. A computer-readable storage device comprising instructions that, when executed by a processing unit of a computing device, cause the computing device to:
-
receive a digital image of a surface of a check, wherein a check scanning device captures the digital image as the check moves through the check scanning device, wherein a fingerprint is impressed on the surface of the check and the digital image includes a fingerprint image; use the fingerprint image to determine an initial match score for the fingerprint; calculate a fingerprint image quality metric of the fingerprint image, the fingerprint image quality metric being a number based on at least one or more changes made to the fingerprint image; adjust the initial match score based on the fingerprint image quality metric to create an adjusted match score; and cause a workstation device to present an alert when the adjusted match score exceeds an alert threshold. - View Dependent Claims (15, 16, 17, 18, 19, 20)
