Check alteration detection system and method
First Claim
1. In combination in a system for determining whether check information printed on the face of a check has been modified comprising:
- a first computer means for printing check information on the face of a check, including means for converting said printed check information to a first digital value;
a second computer means for capturing and processing said printed check information, including scanning means for capturing said printed check information from the face of said check and means for converting the captured printed check information to a second digital value;
means for conveying in a MICR line or paid issuance file said first digital value to said second computer means; and
said second computer means further comprising a comparison routine for comparing said first digital value to said second digital value to discern a match therebetween, wherein said second computer means further comprises means for iteratively evaluating one or more field position for which more than one value may exist to determine if a changed value will produce a match.

Abstract
A system and method for detecting and thus preventing check fraud utilizing a digital computer with image capture and interpretation systems. The system converts the payee information, issue date and the MICR line information (account number, check number and dollar amount) to a check digit which is then placed into the MICR line of a check, printed on its face or transmitted via the paid issuance file to the drawee bank. The drawee bank, upon presentment utilizes a transformation algorithm to convert the printed payee information and issue date on the check into a numerical value that is combined with MICR line information and a check digit is calculated based upon pre-agreed logic. This unique data processing system quickly confirms properly presented checks while effectively precludes payee and other alterations in a cost effective manner.

10. A banking fraud prevention process using a digital computer and utilized to prevent the submission for payment of checks having information printed on the face of the check altered, comprising the steps of:
-
converting the printed check information to a first digital value via a predetermined but not publicly known algorithm; receiving a presented check having said printed check information printed thereon; converting the presented check information to a second digital value via said predetermined algorithm; comparing said first digital value and said second digital value to determine whether a match exists; and when a match does not exist, reconverting said presented check information to a third digital value by iteratively evaluating one or more field positions for which more than one value may exist and using an alternate value to determine said digital third value and comparing said third digital value to said first digital value to determine whether a match exists. - View Dependent Claims (11, 12, 13, 14, 15, 16)
