Abstract
An anti-counterfeiting method, system, and non-transitory computer readable medium an anti-counterfeiting system, include a production circuit configured to produce a Directed Self-Assembly (DSA) pattern including a unique pattern, an analysis circuit configured to analyze the unique pattern, an embedding circuit configured to embed the unique pattern on a document, and a verification circuit configured to verify that the unique pattern embedded on the document corresponds to the document.
