We show numerically that the label is unclonable without access to a secret key - the starting problems of this design algorithm. But, because of the key, it's straightforward to reproduce a tag displaying the expected fingerprint. Several tags happen understood, implemented as plasmonic meta-holograms, and characterized experimentally. The robustness associated with the tag to fabrication mistake and its particular resilience to counterfeiting are studied in more detail and demonstrated experimental
