Multi-mode structural-color anti-counterfeiting labels based on physically unclonable amorphous photonic structures with convenient artificial intelligence authentication

The first physically unclonable anti-counterfeiting label based on structural colors was enabled by interfacing amorphous photonic structures with artificial intelligence. The showing of the structural colors by water, the unique spectra shifts and the artificial-intelligence decodable amorphous arrangements constituted three-level security functions, which add a new dimension to current anti-counterfeiting technology.
