Abstract: PROBLEM TO BE SOLVED: To provide a data processing system and a data processing method for restoring the basic password of a client computer system remotely. SOLUTION: When the basic password is not correctly inputted, a user cannot access the client computer system in a complete form. The client computer system is connected to a server computer system by using a network. The input of the basic password is requested from the user before the client computer system completes a boot process. An inquiry-type password method is supplied in response to the input error of the basic password. The basic password can be restored in response to the normal performance of the inquiry-type password method. The basic password can be restored from the server computer system by the client computer system before the boot process is completed by using the inquiry-type password method by the client computer system.

Abstract: PROBLEM TO BE SOLVED: To provide a data processing system and a method protecting a USB device to enable the USB device to be available only by a connected computer system. SOLUTION: The USB device is not connected with any computer systems until it is used for the first time. When the USB device is used and connected with a specific computer system for the first time, it is connected with the specific computer system included in the data processing system. The USB device is initially incapacitated and turns to be available by responding only to the connection with the connected computer system. The USB device and the connected computer system are connected by using a pair of the encryption keys. Here the connected computer system memorizes the first key and the USB device memorizes the second key.
