ABSTRACT:
Authentication of a casino game data set is carried out within the casino game console using an authentication program stored in an unalterable ROM physically located within the casino game console. The casino game data set and a unique signature are stored in a mass storage device, which may comprise a read only unit or a read/write unit and which may be physically located either within the casino game console or remotely located and linked to the casino game console over a suitable network. The authentication program stored in the unalterable ROM performs an authentication check on the casino game data set at appropriate times, such as prior to commencement of game play, at periodic intervals or upon demand. At appropriate occasions, the contents of the unalterable ROM can be verified by computing the message digest of the unalterable ROM contents and comparing this computed message digest with a securely stored copy of the message digest computed from the ROM contents prior to installation in the casino game console.
