Femtosecond Laser‐Induced Recrystallized Nanotexturing for Identity Document Security With Physical Unclonable Functions

Abstract Counterfeit identity (ID) documents pose a serious threat to personal credit and national security. As a promising candidate, optical physical unclonable functions (PUFs) offer a robust defense mechanism against counterfeits. Despite the innovations in chemically synthesized PUFs, challenge...
