A method of authenticating objects is disclosed. At least one object having a print region with printed material contained thereon is provided. The printed material of the print region includes a layer of non-visible indicia which emits at least one wavelength of light outside a visible range of an electromagnetic spectrum when stimulated with electromagnetic radiation. An optical image of the object is recorded with an imaging device to make the non- visible indicia perceivable to a human eye. The perceived image is then compared against expected authentication indicia to authenticate the object. A system for authenticating objects includes at least one imaging device to record optical images of objects having a layer of non-visible indicia and to render the non-visible indicia perceivable to a human eye. The system also includes a central authentication system in communication with the imaging device to receive optical images recorded by the imaging device.

L'invention concerne un procédé servant à authentifier des objets. Au moins un de ces objets présente une zone d'impression sur laquelle est apposé un matériau imprimé. Ce matériau imprimé comprend une couche d'indice non visible émettant au moins une longueur d'onde lumineuse hors de la portée visible du spectre électromagnétique quand elle est stimulée par un rayonnement électromagnétique. Une image optique de l'objet est enregistrée au moyen d'un dispositif de prise d'image afin de rendre ces indices non visibles perceptibles pour l'oeil humain. L'image perçue est ensuite comparée à des indices d'authentification attendus afin d'authentifier l'objet. Système servant à authentifier des objets et comprenant au moins un dispositif de prise d'image servant à enregistrer des images optiques d'objets possédant une couche d'indices non visibles et à rendre ces indices non visibles perceptibles pour l'oeil humain. Ce système comporte également une unité d'authentification centrale communiquant avec le dispositif de prise d'image afin de recevoir les images optiques enregistrées par ce dispositif.
