A system and method using microcoded marks provides retrospective identification of articles. An article is marked with microparticles having multiple layers. The particles form a unique spatial pattern on the article. An image is made of the mark as applied to the article. The digitized image is stored in a database with information about the article. The database can be accessed by users to verify the authenticity of an article.
