Abstract
Systems and methods of recognizing a business document and creating a document signature. In one embodiment, a business document is scanned and a business document image is created. The business document image is compared to a template database. If a matching template is found, document fields are defined and extracted. If no matching document template is found, the document image is compared to a skeleton database. If a matching document skeleton in found, document fields are defined and extracted. A document skeleton is generated and then stored in the template database. If no matching document skeletons are found in the skeleton database, document fields are manually extracted. A document skeleton is then generated from the identification of static and variable strings and stored in the skeleton database. Document fields are validated after all document fields have been extracted.
