ABSTRACT:
In a method for manufacturing instant lottery tickets where book numbers and ticket numbers are printed on the tickets utilizing a dual security process such that the book numbers are shuffled in each pool before the tickets are printed to break the link between the book numbers the ticket numbers or validation numbers, a reversing process can be used under certain predefined conditions to relate the original book numbers to the ticket numbers or validation numbers. In one example, where a shuffling algorithm utilizing seeds is used to shuffle the book numbers, the seeds used in the algorithm are maintained in an encrypted file. A decryption key for the encrypted seed file can be used by a lottery administration or trusted third party to reconstruct game play indicia for game adjustment purposes and manufacturing adjustments. To enhance security, the independent third party can also be used to administer the encryption and decryption keys during the ticket manufacturing process and during life of the instant ticket game.
