1. An antitheft apparatus comprising:
- a device attached to a movable body, operated by electric power supplied from the movable body, and storing an owner'"'"'s specific authentication code;
an authentication code storage and transmission unit capable of storing an authentication code equivalent to the owner'"'"'s specific authentication code and capable of transmitting a signal of the authentication code to the device;
an authentication code reception unit capable of receiving the signal of the authentication code transmitted from the authentication code storage and transmission unit when the device is operative; and
a control unit for making a decision that a legitimate owner of the movable body is using the movable body when the authentication code received by the authentication code reception unit coincides with the owner'"'"'s specific authentication code stored in the device.

Abstract
A vehicle is equipped with an electronic device having a micro-computer which controls the operations of a playback unit for playing back sound data, and so on. A wireless unit is connected to the micro-computer. When an authentication code from an authentication transceiver is not received by the wireless unit or does not coincide with owner'"'"'s specific authentication data stored in the electronic device in the condition that the electronic device is made operative by electric power supplied from the vehicle, information indicating occurrence of an abnormality is output.

8. An antitheft system comprising:
-
an antitheft apparatus including;
a device attached to a movable body, operated by electric power supplied from the movable body, and storing an owner'"'"'s specific authentication code;
an authentication code storage and transmission unit capable of storing an authentication code equivalent to the owner'"'"'s specific authentication code and capable of transmitting a signal of the authentication code to the device;
an authentication code reception unit capable of receiving the signal of the authentication code transmitted from the authentication code storage and transmission unit when the device is operative;
a control unit for making a decision that a legitimate owner of the movable body is using the movable body when the authentication code received by the authentication code reception unit coincides with the owner'"'"'s specific authentication code stored in the apparatus; and
an abnormality occurrence output unit for outputting information indicating occurrence of an abnormality; and
an external server which acquires information indicating occurrence of an abnormality from the antitheft apparatus and transmits the acquired information, wherein the control unit controls the abnormality occurrence output unit to output the information when the control unit makes either a decision that the signal of the authentication code transmitted from the authentication code storage and transmission unit is not received by the authentication code reception unit in a condition that the device is operative or a decision that the authentication code received by the authentication code reception unit does not coincide with the owner'"'"'s specific authentication code stored in the device.

9. An antitheft system comprising:
-
an antitheft apparatus including;
a device attached to a movable body, operated by electric power supplied from the movable body, and storing an owner'"'"'s specific authentication code, and having a function for acquiring location information indicating a current location of movable body;
an authentication code storage and transmission unit capable of storing an authentication code equivalent to the owner'"'"'s specific authentication code and capable of transmitting a signal of the authentication code to the device;
an authentication code reception unit capable of receiving the signal of the authentication code transmitted from the authentication code storage and transmission unit when the device is operative;
a control unit for making a decision that a legitimate owner of the movable body is using the movable body when the authentication code received by the authentication code reception unit coincides with the owner'"'"'s specific authentication code stored in the apparatus; and
an abnormality occurrence output unit for outputting information indicating occurrence of an abnormality and information indicating a current location of the movable body by transmitting the information to an external portion through a wireless transmission medium; and
an external server which acquires information indicating occurrence of an abnormality and location information indicating a current location of the movable body from the antitheft apparatus, consecutively updates the location information acquired after acquisition of the information indicating occurrence of an abnormality, and transmits the updated location information, wherein the control unit controls the abnormality occurrence output unit to output the information when the control unit makes either a decision that the signal of the authentication code transmitted from the authentication code storage and transmission unit is not received by the authentication code reception unit in a condition that the device is operative or a decision that the authentication code received by the authentication code reception unit does not coincide with the owner'"'"'s specific authentication code stored in the device.
