Abstract

La présente invention se rapporte à un marquage constitué d'un matériau polymère à cristaux liquides ayant des caractéristiques optiques déterminées permettant son authentification et sa lecture par une machine et son authentification par l'Sil humain. Le marquage est appliqué sur un objet, un bien ou un article par un procédé d'impression d'informations variables. Le marquage se présente sous la forme de timbres représentant un code unique qui permet une authentification aisée par l'Sil humain et un suivi et un traçage sûrs de l'objet, du bien ou de l'article marqué pendant toute sa durée de vie.
