Document fingerprinting
First Claim
1. A method, comprising:
- capturing a first digital image of a physical object;
parsing the digital image into at least one region of interest;
extracting identifying information from the region of interest, the identifying information including at least one feature of the region of interest;
combining the at least one feature for each region of interest to form a digital fingerprint of the object;
storing the digital fingerprint in a database, wherein the database comprises a plurality of digital fingerprints each associated with a corresponding physical object;
subsequently, obtaining a second digital image of a second physical object;
parsing the second image into at least one region of interest of the second object;
extracting identifying information from the region of interest, the identifying information including at least one feature of the region of interest of the second object;
combining the at least one feature for each region of interest to form a digital fingerprint of the second object;
comparing the digital fingerprint of the second object to the digital fingerprints stored in the database; and
responsive to the comparison, return an indication as to whether the second object is the first object.

Abstract
An automated document processing machine may comprise an electro-mechanical transport subsystem configured to convey a document through the machine, and a camera arranged adjacent the transport and configured to capture an image of a front side of the document. A fingerprinting software component may be configured for processing the captured image of the document to create a unique digital fingerprint of the document based on the front side image, and a software interface may be configured for storing the digital fingerprint in a database of document identifiers in association with a unique alphanumeric identifier so that the document may be subsequently identified in a second processing machine that has access to the database. The digital fingerprint may be responsive to indicia that otherwise appears on the front side of the document, and may comprise data that identifies a document as being unique based on the front side indicia.

15. A method, comprising:
-
capturing a first digital image of a physical object; parsing the digital image into at least one region of interest; extracting identifying information from the region of interest, the identifying information including at least one feature located within the region of interest, wherein the feature naturally occurs on the physical object and is not added to it for purposes of identification; combining the at least one feature for each region of interest to form a digital fingerprint of the object; storing the digital fingerprint in a database, wherein the database comprises a plurality of digital fingerprints each associated with a corresponding physical object; subsequently, obtaining a second digital image of a second physical object; parsing the second image into at least one region of interest of the second object; extracting identifying information from the region of interest, the identifying information including at least one feature of the region of interest of the second object; querying the database to return digital fingerprint records that include at least one feature located in the same region of interest as the feature of the second object; comparing the feature of the second object to the digital fingerprints returned in response to the querying step; and responsive to the comparison, return an indication as to whether the second object is the first object. - View Dependent Claims (16, 17, 18)
