Abstract
A method of producing an authenticatable article. An overt feature is produced in the article using a fabricating technique which is selected based on a material of the article so as to produce the overt feature having predetermined, reproducible macroscopic characteristics as well as random, non-reproducible microscopic characteristics rendering the article physically unique. The overt feature including the microscopic characteristics are imageable using a predetermined imaging technology to produce an overt feature image. An authentication signature is generated based on the overt feature image and stored in a central database. The overt feature may alternatively be produced in an apparatus or means used to manufacture authenticatable articles such that the overt feature including the random, microscopic characteristics is reproduced in the articles. The overt feature and generated authentication code therefore corresponds to articles manufactured using that apparatus or means.
