    • Determination of the authenticity and integrity of various types of documents such as lottery tickets is accomplished by using an electronic verification machine to compare data contained in electronic circuits printed on the document to document data printed on the document. The electronic circuits are printed on the document in conductive or semiconductive ink using, for example, the gravure printing process, and the presence and status of the circuits can be used to verify or authenticate the document. Data can be represented in the electronic circuits by the electrical signature of the circuit which is measured by the electronic verification machine. In the case of lottery tickets, a ticket can be validated by having the electronic verification machine determine which play spots have been removed from the ticket and comparing data on the ticket with the removed play spots to determine a play redemption value for the ticket. Document verification or lottery ticket validation can also be accomplished by transmitting signature data from the electronic circuits via the electronic verification machine to a central computer for comparison with document data.
    • 通过使用电子验证机将打印在文档上的电子电路中包含的数据与打印在文档上的文档数据进行比较来确定诸如彩票的各种类型的文档的真实性和完整性。 电子电路使用例如凹版印刷工艺在导电或半导体墨水中印刷在文件上,并且电路的存在和状态可用于验证或认证文件。 可以通过由电子验证机测量的电路的电气签名在电子电路中表示数据。 在彩票的情况下,可以通过使电子验证机确定已经从票中移除了哪些游戏点,并将票上的数据与已删除的游戏点进行比较,以确定票的玩赎回值,可以验证票。 文件验证或彩票验证也可以通过电子验证机将签名数据从电子电路传送到中央计算机以与文档数据进行比较来实现。
