Claim Text:
1. A method of enabling replay attack prevention for a gaming system in which a player uses a mobile device with an image capturing camera to become eligible for mobile promotions, wherein a replay attack occurs when an unscrupulous person captures multiple images of a promotion-win triggering event and submits the images as multiple entries, thereby attempting to earn multiple promotions for the same event, the method comprising: providing a gaming machine comprising: (i) at least one display device; (ii) a plurality of input devices including: (a) an acceptor of a first physical item associated with a first monetary value; (b) a cashout button actuatable to cause an initiation of a payout associated with a credit balance; (iii) at least one gaming device processor; and (iv) at least one gaming device memory device storing a gaming device program; interacting with a server over a network using the mobile device; receiving, at the server, event image data representing one or more images captured by a user's mobile device of a gaming machine promotion-win triggering event, the occurrence of which entitles the user to a promotion; comparing, at the server, an arrangement of symbols in a symbol matrix obtained from the captured one or more images of a promotion-win triggering event associated with the gaming machine against possible arrangements of symbols in symbol matrixes for a same game to confirm that the captured one or more images represent different winning results; comparing, at the server, at least one or more of values of a credit, denomination, bet and win meters, and progressive meters against possible values of a credit, denomination, bet and win meters, and progressive meters captured within the one or more images to confirm that the one or more images of the event represent a new promotion-win triggering event; and preventing replay attacks where multiple images of a same promotion-win triggering event are submitted as multiple entries by comparing, at the server, a time and geographic location of a promotion-win triggering event against times and geographic locations of previously submitted promotion-win triggering events to confirm that the images represent a new promotion-win triggering event; the server configured to award an entitlement to the promotion upon confirmation of new and unique promotion-win triggering events, but not in a replay attack where multiple images of a same promotion-win triggering event are submitted as multiple entries.
