Abstract:
A method for producing a PUF-film includes printing a layer of dielectric material on a film substrate, such that a variable thickness of the layer is obtained by the printing. The method includes arranging a structured electrode layer on the dielectric material such that the structured electrode layer is influenced with respect to an electric measurement value due to the variable thickness.
