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.
