Abstract
Provided is a security system for managing which CD-ROM is used for a game device not having identifying information in advance. When a game device accesses a server via a communication network, a device ID, which is issued from the server, is stored in a nonvolatile memory This device ID is generated based on the time and date when the game device accesses the server via a communication network (e.g. Dec. 10, 2000 at 21:05:37). The server associates a serial number (SN) of a CD-ROM used in the game device and a device ID of the game device with each other and registers them on a database This makes it possible to manage which CD-ROM is used in each game device.

1-7. (canceled)
A data processing device for processing saved data in a backup memory, comprising:
- means for storing identifying information inherent in said data processing device;
- means for encrypting said saved data using said identifying information inherent in said data processing device as a key.
A data processing method for encrypting saved data in a backup memory using identifying information inherent in a data processing device as a key.
13-14. (canceled)
A security system comprising:
- means for registering in a database the number of times that a data processing device having a backup memory is connected to a communication network while recording said number of times in said backup memory or said data processing device and
- means for, upon said data processing device being connected to a communication network, when said number of times obtained from said data processing device is consistent with the number of time registered in said database, permitting the processing of said data in said backup memory.
A method for managing a saved data comprising the steps of:
- registering in a database the number of times that a data processing device having a backup memory is connected to a communication network while recording said number of times in said backup memory and said data processing device;
- and,
- upon said data processing being connected to a communication network, when said number of times obtained from said data processing device is consistent with the number of times registered in said database, permitting the processing of the data in said backup memory.
A game server comprising:
- means for setting in advance a level required to participate in a communication game in accordance with the difficulty of said game;
- and
- means for allowing a player complying with the required level according to the difficulty of said game to participate in said communication game.
A game processing method for not saving progression status of a game when a communication game is played via a communication network.
A game processing method for shortening a displaying time of an ending screen of a game when a communication game is played via a communication network.
