A method for the protection against unauthorized use of an apparatus running on an electric current, whereby at least one external first code word presented to the apparatus is processed in the apparatus, and on the basis of the thus obtained processing result, the apparatus being switched either to at least partial deactivation or released, and where the occurrence of at least one predetermined event is verified by the apparatus after that the apparatus is fed by electric current for the first time, and after determining that said event has occurred, a second code word is generated by the apparatus that thereupon is presented to at least one monitoring station, wherein the first code word is thereafter determined on the basis of the second code word. |
