SYSTEM AND METHOD FOR SECURING ON-LINE DOCUMENTS USING AUTHENTICATION CODES

摘要

A system and method for providing an authentication code across a network for use in authentication of documents, such as printed lottery tickets. Th e system includes document-printing terminals that include a key that is use d in a mathematical function with the bet information for a specific-game en try to generate a document code that is sent to a central server. The centra l server stores the received document code and then generates an authenticat ion code for the document desired to be printed at the terminal, and sends t he authentication code back to the terminal for printing on the issued docum ent. The authentication code can be a further mathematical processing of the document code. Verification of the document occurs from comparison of the a uthentication code on the document and stored authentication and/or document codes at the server.
