Fingerprint check to reduce check fraud
First Claim
Patent Images
1. A method comprising:
- receiving, at a computing system, 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;
using, at the computing system, the digital image to determine a match score, the match score representing an approximate probability that the fingerprint on the check matches a reference fingerprint, matching being performed by;
generating a target fingerprint template that represents the fingerprint;
storing a plurality of reference fingerprint templates, each of the reference fingerprint templates representing a fingerprint of a different person, the plurality of reference fingerprint templates including a reference fingerprint template representing the reference fingerprint; and
calculating the match score by comparing the target fingerprint template and the reference fingerprint template;
presenting an alert based on the match score; and
performing, at the computing system, a learning process that seeks to reduce a rate of false matches and false non-matches by monitoring at least one occurrence of a false match and/or a false non-match and adjusting at least one reference fingerprint template.

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 a match score. The match score represents an approximate probability that the fingerprint on the check matches a reference fingerprint. An alert is presented based on the match score.

10. A computing device comprising:
-
a processing unit; and a computer-readable medium comprising instructions that, when executed by the processing unit, cause the computing device to; determine a match score by comparing a target fingerprint template and a reference fingerprint template, the target fingerprint template representing a fingerprint impressed on a check, the target fingerprint template generated from an image of the check, the image of the check captured by a check scanning device as the check moved through the check scanning device, the reference fingerprint template representing a reference fingerprint, the match score representing an approximate probability that the fingerprint on the check matches the reference fingerprint; cause a workstation device to present an alert when the match score exceeds an alert threshold; and cause the computing device to perform a learning process that seeks to reduce a rate of false matches and false non-matches by monitoring at least one occurrence of a false match and/or a false non-match and adjusting at least one reference fingerprint template. - View Dependent Claims (11, 12)
