A technology precluding attacks through peripheral devices (410, 420, 430, 440, 450) thefts to a network of electronic appliance, by utilizing physical chip identification devices (60, 21, 22), is disclosed. The electronic appliance in the network are divided into the peripheral devices (410, 420, 430, 440, 450) and stem servers (400, 1400, 2400, 3400) managing registration information of the peripheral devices (410, 420, 430, 440, 450), wherein the stem servers (400, 1400, 2400, 3400) serve as central control using software, and the peripheral devices (410, 420, 430, 440, 450) are managed at device-level by having physical chip identification devices (60, 21, 22), thus the security of the whole network is efficiently reinforced. |
