A PUF-film comprises a flat circuit structure comprising a plurality of circuit elements and comprises a flat electric shield. The circuit structure is evaluable with respect to a plurality of electric capacitance values being arranged between the plurality of circuit elements. The electric shield at least partially covers the circuit structure and provides for a counter reference electrode of the plurality of electric capacitance values.
