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.
