Nanobarcodes particles as covert security tags for documents and product security

At Nanoplex Technologies, Inc. we have developed Nanobarcodes particles, which are encodeable, machine-readable, durable, sub-micron sized taggants which have application for document and product security. We will present results on the use of Nanobarcodes particles in a number of authentication and anti-counterfeiting applications. We also focus on the software component in recognition of particles imaged against varied backgrounds.
