ABSTRACT:
In a network implemented based on IEEE 1394, when an HDD is connected to a personal computer via an IEEE 1394 connection unit and a GUID terminal connection unit, the HDD obtains a GUID via the GUID terminal connection unit. When the personal computer requests acquisition of an access right, the HDD obtains a GUID via the IEEE 1394 connection unit, and compares it with the GUID obtained via the GUID terminal connection unit, and since the GUIDs match, the HDD assigns an access right to the personal computer. Even if another personal computer not connected to the HDD via the GUID terminal connection unit, transmits a GUID to the HDD via the IEEE 1394 connection unit, because the GUID differs from that of the personal computer connected to the HDD via the GUID terminal connection unit, an access right is not assigned to the personal computer not connected to the HDD via the GUID terminal connection unit.
