<p><P>PROBLEM TO BE SOLVED: To provide a game system capable of securing the properness of a password input when a game is started. <P>SOLUTION: A game machine previously stores one or a plurality of character information strings in which character information capable of expressing player information is arrayed, and creates starting instruction information including information on any one character information string when a starting instruction to start a game is received. An information processing server previously stores the character information string, and stores game history information on the game played in the game machine. When the starting instruction information is received, the information processing server creates authentication information for authenticating the player information by using the player information and the starting instruction information. The information processing server creates the authentication information and authentication information added player information. The game machine creates the starting instruction information with a bit number which is not more than the bit number in the bit sequence of the player information at the time and which includes information on the character information string. The information processing server creates the authentication information by using the bit sequence of the received starting instruction information and the bit sequence of the player information. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
