Abstract

Cette invention concerne un procédé et un appareil qui permettant de détecter la présence de particules dans un substrat. Le matériau de base de ce substrat possède des propriétés électromagnétiques qui diffèrent sensiblement des propriétés électromagnétiques correspondantes desdites particules. Cette invention concerne également ces particules ainsi que le substrat qui contient de telles particules. Il est ainsi possible d'identifier facilement un document comme étant un document sécurisé original, ceci afin d'éviter qu'il ne soit copié ou afin de contribuer à son authentification.
