Abstract: An automated method for capturing data from electronic images of commercial documents such as invoices, bills of lading, explanations of benefits, etc. is described. An optimal mapping between the fields of interest in an image of a page of a document and the corresponding fields of a pre-trained image of a page of a similar document is defined. This mapping allows an automatic precise extraction of data from the fields of interest in an image regardless of distortions the image is subjected to in the process of scanning.

Abstract: An automated method for assembling common commercial documents such as invoices, bills of lading and purchase orders placed in multipage files containing multiple documents without separators is described. The method is applicable in the presence of attachments and utilizes training data consisting of fields of interest and their locations in documents together with invariant fields frequently present in documents.

Abstract: An automated method for generation of training samples for classification of electronic images of commercial documents such as invoices, bills of lading, explanations of benefits, etc. is described. An image of a page of a document is generated as a representative of similar pages from the same origin regardless whether the page of the document contains permanent and variable information or just permanent information.

Abstract: A method of electronically endorsing a check includes obtaining an electronic image of the check and composing an endorsement data element for the check that includes at least first information identifying a party endorsing the check. The method further includes creating a message data file including the electronic image and the endorsement data element, and creating a signed message data file that includes the message data file and a digital signature of the message data file creating using a private key. The private key may be specific to the party endorsing the check or to an electronic device with which the method is implemented. Also, a method of performing an inquiry relating to a check that was endorsed as described above using the endorsement data element.
