Abstract
A method for authenticating an article including engraving a circular feature into a verification substrate that includes a plurality of concentric rings within the circular feature arranged in a pattern according to a data encoding schema, wherein at least one of the plurality of rings includes a surface anomaly. The method can include capturing a first image of the circular feature and storing the first image in a memory device. The verification substrate can be attached to an article to traced and/or authenticated. A second image of the circular feature can be captured and compared with the first image to determine if the surface anomaly is present in the second image, thereby authenticating the article.
