<P>PROBLEM TO BE SOLVED: To provide a game system capable of preventing such a fraud that an image itself of code information containing game history information is uploaded. <P>SOLUTION: When a start operation is executed, a game machine acquires a random number value (a QR identification counter), displays a first QR code containing the acquired random number value and, when an end operation is executed, displays a second QR code containing the random number value and the game history information. When there is an access from a cellular phone or the like via the first QR code, a server registers the random number value contained in the first QR code. Alternatively, when there is an access from the cellular phone or the like via the second QR code, the server executes an authentication process based on the registered random number value and, when the authentication is succeeded, stores the game history information contained in the second QR code. If the random number value contained in the first QR code has been already registered in another game machine, the server does not register the random number value and allows the cellular phone or the like to display an error image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
