Abstract
Multiple polynucleotides with random sequences are collectively used as a molecular anti-counterfeiting tag. The polynucleotides are placed on an item as a molecular identifier of authenticity. Each position within the random sequences is synthesized using a predetermined ratio of nucleoside bases. With this technique the sequence of each polynucleotide is random but the ratio of nucleoside bases over the collection of synthetic polynucleotides is not. Verification of authenticity is achieved by sequencing a portion of the polynucleotides collected from the item and calculating the ratio of nucleoside bases at each position. If these ratios are the same or similar to the ratios used for synthesizing the polynucleotides, then the item is identified as authentic. The ratios of nucleoside bases and a description of the item may be stored in an electronic record that is used for validating authenticity of the item.
