Methods for tagging and tracing materials using nucleic acids as taggants allow for the identification of diverse materials. The process of tagging involves altering a substance in a manner that allows for the subsequent identification of the substance by detecting the alteration. The alteration disclosed herein involves nucleic acids. The methods are especially useful when the nucleic acid taggant is amplified prior to the identification step. L'invention concerne des procédés d'étiquettage et d'indication de matières en utilisant des acides nucléiques comme agents d'étiquettage pour identifier diverses substances. Le procédé d'étiquettage consite à altérer une substance de manière à permettre son identification ultérieure par détection de son altération. L'altération s'effectue en utilisant des acides nucléiques. Les procédés sont particulièrement utiles lorsque l'agent d'étiquettage tel qu'un acide nucléique est ampllifié avant la phase d'identification.
