<p>An electrical field product method for preventing burglary and an apparatus thereof for authenticating a user by using a CAN communication when the battery is separated are provided to prevent burglary after temporarily attaching or separating the battery. An electric field product senses the power supply interruption from a battery(S400). If it perceives the cut off of the electric power supply to the electric field device, the apparatus is in a locked state(S402). If the power source is again supplied to the electric field device, the apparatus transmits the authentication data require-message in the authentication unit(S404, S406). If authentication data are received from the authentication unit, the apparatus determines whether data registered by the electric field device and received authentication data(S408, S410). If the received authentication data as described above coincides with the registered data as described above, it has the apparatus with the cancel release to lock of the electric field device(S412).</p> |
