"PROCESSES TO GENERATE A DOCUMENT, AND TO VERIFY THE AUTHENTICITY OF A DOCUMENT, AND, SYSTEM TO GENERATE DOCUMENTS". A process of generating documents and verifying their authenticity first requires controller access to a document creation system so that only authorized users can create documents. User data that identifies a system user is recorded, and verification data is generated from both user data and data corresponding to documents generated using the system. Authentication data corresponding to the verification data is recorded, and the document is then printed with a machine-readable part containing the verification data. The machine-readable part is typically a barcode or two-dimensional symbol. When the document is presented, the verification data is read from it, for example by optical scanning, and compared with retrieved authentication data to indicate whether or not the document is authentic.
