    Patent number: 11040564
    Abstract: The invention relates to a method for forming and detecting security elements on the surface of a component and/or in a component, in which at least one layer or at least one region that is preferably formed of a magnetic material or of a material different from the component material is formed on the surface of the component and/or in the component that is formed of a magnetic or of a nonmagnetic material in a locally and geometrically defined manner. At least one ablated track, at least one heat-affected region and/or at least one remelted treatment track are/is formed by a locally and geometrically defined ablation of material or input of energy on/at the surface of a component along a predefined contour corresponding to the respective security feature.
