La présente invention concerne un système et un procédé de génération et de vérification d'étiquettes holographiques permettant d'identifier des articles contrefaits. Le procédé consiste à combiner l'utilisation d'un texte caché de moiré ou d'un texte à l'envers avec une étiquette holographique à codage unique, le code lui-même étant imprimé sur l'hologramme à l'aide d'un code QR, d'un code de matrice de données ou d'un modèle de codage similaire. Pour vérifier l'étiquette holographique, l'utilisateur balaye l'étiquette à l'aide d'une application mobile sur le dispositif utilisateur. S'il s'agit d'un article authentique, l'utilisateur en est informé et, d'autre part, s'il s'agit d'un article contrefait, on le notifie à l'utilisateur. Ceci permet aux utilisateurs de faire un choix éclairé quant à leur achat en vérifiant l'authenticité d'un article.
