Abstract (en)

[origin: WO0199076A1] The invention concerns a magnetically marked paper document and a device for sensing magnetically marked paper document. The device comprises excitation means (A1, A2, A3) for varying in time the magnetisation of amorphous ferromagnetic filaments sheathed in glass contained in the marked document and means for sensing the variation in magnetisation of the ferromagnetic filaments. The invention is useful for controlling reproduction of documents and authentication of documents.
