Abstract
When an online ticket is purchased, a record is maintained in a third-party online service; the record does not include the unique serial number of the ticket. The unique serial number is salted and/or hashed to generate a unique cryptographic value, which is stored with the record by the service. When the online ticket is redeemed, the unique serial number is again salted and/or hashed to produce a candidate cryptographic value. The records of the service are searched using the candidate cryptographic value and upon a match, the appropriate matching record is returned to the redeeming entity associated with the ticket by the service as evidence of authentication and as auditing information associated with the original purchased ticket.
