Zusammenfassung:	Methods for manufacturing a supply item for an imaging device having a helical physical unclonable function are disclosed. The helical physical unclonable function may be used to authenticate a supply item for an imaging device. Measurements of the magnetic field above a helical flight are stored in a non-volatile memory to be used by an imaging device to authenticate the supply item. Other systems and methods are disclosed. Se describen métodos para producir un artículo de suministro para un dispositivo formador de imágenes que tiene una función física, helicoidal no duplicable. La función física, helicoidal no duplicable se puede usar para autentificar un artículo de suministro para un dispositivo formador de imágenes. Se almacenan mediciones del campo magnético por encima de un filete helicoidal en una memoria no volátil para que se usen por un dispositivo formador de imágenes para autentificar el artículo de suministro. Se describen otros sistemas y métodos.
