A system and method for encoding and authenticating documents and data storage discs uniquely is described which can provide a means to authenticate a document such as a passport or identification document or driving licence or contract or a music compact disc (CD) or data CD or DVD or holographic DVD or credit card. The documents each comprise an encoding formed from a unique number or pattern or datagram image, which is either printed so that it can be read directly by a viewing device, or the encoding is cut by laser to create a pattern or perforation matrix into the document thereby leaving the unique number or pattern or datagram as a matrix of small holes or perforations in the document through which light may pass. The authentication process thus involves viewing and decoding the encoding and generating a computed result using a stored decoding algorithm. Different levels of decoding may be linked to subscriber access privileges and these may be controlled by subscriber identity data and or a finger print capture and validation sensor.
