Demonstration of an Authentication Technique on an International Supply Chain
Keywords: Authentication Technique, Supply Chain Trust, Counterfeit Avoidance
To stop counterfeit products being introduced into assembled systems, manufacturers of critical systems must use checks and safeguards to ensure that the parts and modules contained within their systems are not counterfeit. These safeguards can range from specially designed tests, to aggressive overt and covert authentication techniques. In this paper, we present the use of microtaggants at the electronic product level as an authentication technique. We utilize a 2D barcode (data matrix) “sealed” with the taggant concealed within it. The taggants are complimented with secure dual purpose reader and a trust management software. The application of the tool is demonstrated for purchase of commercial electronic product by a major military contractor.
