ABSTRACT:
A system and method for authenticating documents and content thereof. A counterfeit resistant document recording medium is provided, having thereon a predefined unique document identifier and at least one security feature. The recording medium is thereafter imprinted with document content, which typically varies between documents. The document content is stored in a database, indexed by an associated document identifier. The document may then be authenticated by checking the security feature and comparing the stored document content with a perceived document content. The system provides a number of opportunities for commercial exploitation, including sales of identified recording media, recording of information in a database, on-line authentication transactions, differential accounting for document validations and counterfeit identifications, imprinting devices, authentication devices, and the like. The system prevents counterfeiting of valuable documents through casual means by providing both physical and logical security.
