Claim:
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, one or more values of one or more game meters against possible values of one or more game 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 a 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.
