CA 2441219

The present invention in one aspect is directed to a method for labeling the durable surface of an object for its identification, which object has a durable surface or a durable surface tag affixed to the object. This method includes the use of "pit and fall" (i.e.., holes and bumps as are used to record compact discs, CD-ROMs) technology to encode durable surface objects with coded message. The coded message can be information on the owner, a history of the object, or any other information desired. The coded message would not be detectable to the human eye; however, by scanning the pits and falls with a laser, the coded message could be detected and displayed. Such coded message encoding could be used, for example, to label objects for their identification in case of theft, or in case of product counterfeiting or diversion.

Un aspect de l'invention concerne un procédé permettant d'effectuer un marquage sur la surface durable d'un objet dans le but de son identification, l'objet présentant une surface durable ou une pièce de marquage à surface durable apposée audit objet. Ce procédé consiste à utiliser une technologie de "creux et de bosses" (pareille à celle utilisée pour enregistrer des disques compacts, CD-ROM etc.) pour coder des objets à surface durable au moyen d'un message codé. Ledit message codé peut être une information relative au propriétaire, à l'histoire de l'objet, ou tout autre information voulue. Le message codé n'est pas détectable à l'oeil humain; cependant au moyen d'un balayage laser des creux et des bosses, le message codé peut être détecté et affiché. Le codage d'un tel message codé peut être utilisé, par exemple, pour marquer des objets dans le but d'une identification en cas de vol, ou en cas de contrefaçon ou de détournement de produits.
