DNA trademark

Germany has developed two improved anti-counterfeiting methods based on recognition technology. Molecular fingerprinting technology uses a high-precision keyboard coding mechanism to provide basic anti-counterfeiting protection based on synthetic DNA. Between 1012 and 1016, special user code can be generated. Usually these codes are pasted as labels or printed directly on folding cartons and other products. The seminar demonstrated the use of inkjet printing on food packaging for anti-counterfeiting labels. This practical example provides valid evidence for the following three steps.
â–  Determination of related value (single-stranded DNA)
â–  Incorporation into the trademark (Additions to the 2nd DNA strand)
â–  Confirmation of the machine-readable signal It is believed that it is only a matter of time to incorporate this technology into offset printing.
High-security trademarks with nano-optical barcodes are another possible way to distinguish between genuine and defective products. In this case, a label consists of a reflective layer, a barrier film, and a metal layer with nanoparticles. The label is attached as a seal to the product packaging and adds more than 15 parameters of coding information to the label. This tag can also incorporate other additional elements such as company logos and bar codes. The authenticity of this seal is determined by a dedicated portable scanner or high-speed reader.
