the control unit displays the information of the portable electronic device received by the second receiving unit on the display unit when the identification data received by the receiving unit does not correspond with the predetermined identification data.
5 . The security system according to claim 1 , wherein the other information device includes a third receiving unit that receives an identifying information of the information device and the identification data over the network, a third storage unit, and a second control unit that stores the received identifying information of the information device in association with the received identification data in the third storage unit.
6 . The security system according to claim 5 , wherein the second control unit keeps the other information device not usable when the enabling signal is not received.
7 . The security system according to claim 6 , wherein the other information device further includes a second display unit and
the second control unit displays the information of the portable electronic device based on the received identification data on the second display unit when the other information device is not usable.
8 . A portable electronic device comprising:
a first storage unit in which an unique identification data is stored; and
a first transmission unit that transmits the identification data to information device including a receiving unit that receives the identification data from the portable electronic device, a second transmission unit that transmits data over a network, a second storage unit in which predetermined identification data and an address of the other information device are stored, and a control unit that transmits an enabling signal to the address over the network when the identification data corresponds with the predetermined identification data.
9 . The portable electronic device according to claim 8 , wherein the information device further includes an operating unit for operating the information device, and
the control unit starts the receiving unit in response to a operation performed on the operating unit.
10 . The portable electronic device according to claim 8 , wherein the second storage unit further stores an identifying information of the information device, and
the control unit controls the second transmission unit so as to transmit the identifying information of the information device; and the identification data to the address over the network.
11 . The portable electronic device according to claim 8 , wherein the information device further includes a display unit and a second receiving unit that receives information of the portable electronic device over the network and
the control unit displays the information of the portable electronic device received by the second receiving unit on the display unit when the identification data received by the receiving unit does not correspond with the predetermined identification data.
12 . The portable electronic device according to claim 8 , wherein the other information device includes a third receiving unit that receives the identifying information of the information device and the identification data over the network, a third storage unit, and a second control unit that stores the received identifying information of the information device in association with the received identification data in the third storage unit.
13 . The portable electronic device according to claim 12 , wherein the second control unit keeps the other information device not usable when the enabling signal is not received.
14 . The portable electronic device according to claim 13 , wherein the other information device further includes a second display unit and
the second control unit displays the information of the portable electronic device based on the received identification data on the second display unit when the other information device is not usable.
15 . A security method among a potable electronic device, a first information device and a second information device, the method comprising the steps of:
transmitting an identification data in the potable electronic device;
receiving the identification data in a receiving unit of the first information device; and
transmitting an enabling signal to the second information device over a network according to a stored address when the receiving identification data corresponds with a predetermined identification data, in the first information device.
