    • A system and 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 include a key that is used in a mathematical function with the bet information for a specific-game entry to generate a document code that is sent to a central server. The central server stores the received document code and then generates an authentication code for the document desired to be printed at the terminal, and sends the authentication code back to the terminal for printing on the issued document. The authentication code can be a further mathematical processing of the document code. Verification of the document occurs from comparison of the authentication code on the document and stored authentication and/or document codes at the server.
    • 一种用于在网络上提供认证码以用于认证文件(例如印刷彩票)的系统和方法。 该系统包括文档打印终端,其包括用于数学功能的密钥,具有用于特定游戏条目的投注信息以生成发送到中央服务器的文档代码。 中央服务器存储接收到的文档代码,然后生成期望在终端上打印的文档的认证码,并将认证码发送回终端,以便在发布的文档上进行打印。 验证码可以是文档代码的进一步的数学处理。 文档的验证是从文档上的认证码和服务器上存储的认证和/或文档代码的比较而发生的。
