Zusammenfassung:	A physically unclonable function is an object that has characteristics that make it extremely difficult or impossible to copy. An array of randomly dispersed hard (magnetized) and soft (non-magnetized) magnetic particles that may be conducting or nonconducting that are disbursed in a binder create a particular magnetic field or capacitive pattern on the surface. This surface magnetic field and capacitive variations can be considered to be a unique pattern similar to fingerprint. The Hall effect prism is a sensor that measures the effects of these patterns by sensing the deformation of currents or electric potential flowing within or around a resistive substrate material that exhibits a substantial Hall effect coefficient.
