Document Uniqueness Verification

Abstract

Reuse of documents to attain fraudulent insurance pay-outs is an increasing global problem. This is alleviated by providing a method (100) of verifying the uniqueness of a digital document by: identifying and extracting data elements (110) of the document (1), assigning the document with a document type (120) based on the presence of at least one keyword data element (121) among extracted data elements, generating a document identifier (130) based on type data (122) being a predetermined plurality of the extracted data elements (110) specific to said document type (120) using an identifier generator algorithm (182), comparing the generated document identifier (130) with a list (140) of document identifiers (130′) stored in a database (180), where if the generated document identifier (130) matches a document identifier (130′) in the list, the document (1) is marked as a duplicate document and an alert signal is transmitted.
