Patent

CA 2648549

A method is disclosed to verify and identify products through their product signatures in order to combat counterfeiting and reduce dispensing errors, using methods such as spectral analysis (e.g., near infrared spectroscopy). Furthermore, in order to actively evade product counterfeiting, a method is disclosed where an amount of one or more components of the product are varied (e.g., over time); the variation provides a different product signature, but falling within a desirable or necessary range.

La présente invention concerne un procédé de vérification et d'identification de produits par l'intermédiaire de leurs signatures de produits dans le but de combattre la contrefaçon et de réduire des erreurs de distribution, à l'aide de procédés tels que l'analyse spectrale (par exemple, la spectroscopie en infrarouge proche). En outre, afin de se soustraire efficacement à la contrefaçon des produits, l'invention propose un procédé dans lequel une quantité d'un ou plusieurs composants du produit est modifiée (par exemple, au fil du temps) ; la variation donne une signature différente du produit, mais rentre dans une plage souhaitable ou nécessaire.
