Abstract: A system method for providing an authentication code across a network for use in authentication of documents, such as printed lottery tickets. The system includes document-printing terminals that create a first key and a second key, with the first key used to generate an authentication code for printing on the document, and the second key is sent to a central server and usable to verify that the first key created the authentication code. The central server can also provide ticket serial numbers for tickets being dispensed at the terminals and the first key can be combined with the serial number and other secondary data to create the authentication code.

Abstract: A method of embedding an optical signature in a document and document produced therefrom. The optical signature is an optical pattern generated from a known value, such as a mathematical, geometric, trigonometric, size, phase, and the like, and the same value can be generated from examination of a document having the embedded optical pattern. The document can be validated, authenticated, or the determination of a valid copy of an original document with the embedded optical signature made through comparison of the known value and the value generated from the optical pattern on the document. The optical pattern can also be generated from other identification codes on the document.
