photoinitiator

UV lamp illuminating security banknote with invisible inks and blockchain hash network for anti-counterfeit protection.
Anti-counterfeit printing combines covert inks that respond to ultraviolet (UV) or infrared (IR) light with serialized codes recorded on a blockchain ledger. The ink binds authentication to the physical item, while the ledger stores one 256-bit cryptographic hash per serial that exposes altered records. The ledger alone cannot confirm that […]
