Abstract
A method for securing an object from forgery involves a seal element having an antenna structure, an object to be secured, and at least one coupling element arranged or arrangeable at the object is supplied. The coupling element influences a value of an oscillating circuit parameter of the antenna structure when the antenna structure is arranged relative to the coupling element at the object. The seal element and the coupling element are arranged at the object such that a relative arrangement of the antenna structure to the coupling element at the object is fixed by which the value of the oscillating circuit parameter of the antenna structure arranged at the object is defined in dependence on the fixed relative arrangement, and serve as an authentication feature of the object. The value of the oscillating circuit parameter can be measured and associated with the object an authentication feature.
