A non-transitory computer-readable storage medium encoded with computer-executable instructions to cause a processor to execute a method for determining whether first and second physical documents identify a same entity, the method comprising: receiving information obtained by a document reader from a first physical document; receiving information obtained by a document reader from a second physical document; comparing a first portion of the information read from the first document with a first portion of the information read from the second document, wherein the first portion of the information read from the first document and the first portion of the information read from the second document are associated with a first parameter describing a person; comparing a second portion of the information read from the first document with a second portion of the information read from the second document, wherein the second portion of the information read from the first document and the second portion of the information read from the second document are associated with a second parameter describing a person; wherein the first parameter and the second parameter are different parameters; when the first portion of the information read from the first document is substantially identical to the first portion of the information read from the second document and the second portion of the information read from the first document is substantially identical to the second portion of the information read from the second document: providing an indication that the first physical document and the second physical document identify a same entity; and when the first portion of the information read from the first document is not substantially identical to the first portion of the information read from the second document or the second portion of the information read from the first document is not substantially identical to the second portion of the information read from the second document: providing an indication that the first physical document and the second physical document do not identify a same entity.
