Abstract

Un système d'authentification (1) comprend : une pluralité d'identifiants d'article uniques (3a, 3b, ... 3n) comprenant chacun un motif configuré de telle manière que chaque image d'une pluralité d'images soit visible suivant un angle respectif ou une orientation respective par rapport à l'identifiant (3a, 3b, ... 3n) ; un moyen de capture d'image (40) servant à capturer des données d'image se rapportant à l'un des identifiants (3a, 3b, ... 3n) ou le représentant ; un moyen de traitement (P) relié de manière opérationnelle au moyen de capture d'image (40) ; et un moyen de mémoire (M) relié de manière opérationnelle au moyen de traitement (P) et dans lequel est stockée une base de données contenant des données d'identification d'articles relatives à deux articles ou plus (2a, 2b, ... 2n) et un code d'article associé à chacun des articles (2a, 2b, ... 2n) ; le système (1) pouvant être utilisé pour capturer, à l'aide du moyen de capture d'image (40), des données d'image dont au moins une partie représente ou concerne la pluralité d'images de l'identifiant (3a, 3b, ... 3n), pour extraire un code d'identifiant dans les données d'image capturées, pour comparer, à l'aide du moyen de traitement, au moins une partie du code d'identifiant aux codes d'article stockés dans la base de données afin d'identifier l'article (2a, 2b, ..., 2n) auquel le code d'identifiant est associé et de récupérer les données d'identification d'article associées à l'article identifié (2a, 2b,... 2n).
