Abstract
A method and system as presented by which valuable documents such as checks, deeds, driver's licenses, and other types of valuable documents can be imprinted with encoded symbols by a printer whereupon multiple assemblages of data can be imprinted on the valued document which is then susceptible to readout by a document reader which will automatically authenticate and verify the originator or the document and its authenticity and obviate any attempts for fraudulent alteration.
