Anti-Counterfeiting Tags High dimensional Ti3C2Tx MXene topographies are generated in a unclonable manner, which can be read with layer-by-layer laser confocal imaging and reconstructed to 3D PUF keys, as demonstrated by Lin Jing, Qian Xie, Po-Yen Chen, co-workers article 2300568. Pairing pick-and-check strategy self-trained Siamese neural network, this anti-counterfeiting technology features ultrahigh encoding capacity, fast processing, high authentication accuracy under various external disturbances including tag rotations, dislocations, mechanical/thermal stresses.
