Abstract

A number of methods of processing checks are provided that enable the various parties involved in processing/clearing the checks to be able to audit the movement of the check, and specifically an image of the check, through the check processing/clearing system. In particular, cryptographic techniques are employed allow the various parties involved in processing/clearing the checks to be able to identify what person and/or process performed an operation on the check, such as scanning the check to create the check image or performing optical character recognition on the check image to obtain data therefrom such as the amount of the

12. The method according to claim 11, wherein said private key is specific to said operator.

18. A method of processing a check, comprising:

receiving a check image file, said check image file including an electronic image of said check and amount information indicating an amount of said check;

performing OCR on the electronic image using an OCR process to obtain an OCR amount for said check;

if said OCR amount matches said amount information, creating a first new signed check image file using at least OCR amount; and

if said OCR amount is not trustworthy and does not match said amount information, creating a second new signed check image file using at least second amount information read by an operator.

19. The method according to claim 18, wherein said step of creating a first new signed check image file includes adding said OCR amount to said check image file as embedded data to create a first new check image file, wherein said first new signed check image file includes said first new check image file and a digital signature of said first new check image file created using a private key specific to said OCR process, and wherein said step of creating a second new signed check image file includes adding said second amount information to said check image file as embedded data to create a second new check image file, wherein said second new signed check image file includes said second new check image file and a digital signature of said second new check image file created using a private key specific to said operator.

20. The method according to claim 18, wherein said OCR amount has a confidence score, wherein said OCR amount is trustworthy if said confidence score exceeds a predetermined threshold level, and wherein said OCR amount is not trustworthy if said confidence score does not exceed said predetermined threshold level.

21. The method according to claim 18, said check image file being part of a signed check image file including said check image file and a digital signature of said check image file, wherein said steps of said method are performed only if said signed check image file can be authenticated, and wherein a fraud investigation is commenced for said check if said signed check image file cannot be authenticated.

22. The method according to claim 19, wherein said step of adding said second amount information to said check image file also includes adding information identifying said operator to said check image file as embedded data to create said second new check image file.

23. A method of processing a check, comprising:

receiving a deposit file, said deposit file including an amount file and a plurality of check image files, said amount file including a plurality of amounts corresponding to a plurality of checks being deposited, said check being one of said plurality of checks, said check image files including a check image file for said check, said check image file for said check including an electronic image of said check;
