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.

L'invention concerne un document de papier marqué ainsi qu'un dispositif de détection de document de papier marqué. Le dispositif comprend des moyens d'excitation (A1, A2, A3) pour faire varier dans le temps l'aimantation de filaments ferromagnétiques amorphes gainés de verre contenus dans le document de papier marqué et des moyens de détection de la variation d'aimantation des filaments ferromagnétiques. L'invention s'applique au contrôle de la reproduction de documents ainsi qu'à l'authentification de documents.
