ABSTRACT:
In an instant lottery ticket system having a lottery administration host computer that includes a ticket validation file, security of the validation file is provided by an audit system that allows periodic audits of the validation file. Audit data, based on ticket data that is used to print the instant lottery tickets, can be compared to the information in the validation file to confirm the integrity of the validation file. The audit data can include all or a portion of the records that should be in the validation file or selected portions of data in the records such as ticket redemption values. Alternatively, the audit data can be computed from the ticket data into a data string for comparison with a data string computed from the validation file. Security can be further enhanced by incorporating time or other variable data in the data strings. The audit data can be transmitted to the host computer or placed on a read only memory for use by the host computer in the audit process.
