Abstract (en)

[origin: EP2246824A2] The protection element has a base and a metallized layer, where the metallized layer represents a single- or multi-layered metallized island layer made of granulated metal. The metallized layer has a nonlinear dependence on the electro-physical characteristics, when the layer is exposed to a weak electric direct current field or alternating current field. The granulated metal contains normal metal, ferromagnetic metal, magnetic metal alloys or non-magnetic metal alloys. An independent claim is also included for a method for authentication of a protection subject.
