a Ternary information recording by using the three basic states of dislocation-formed zones. Scale bars: 5 µm, 20 µm. b Information rewriting by using the reversibility of dislocation generation in the PMN-PT crystal. The dislocation-patterned letter “PT” was first erased and then rewritten as “HL”. Scale bars: 50 µm. c Concept of multi-layer asymmetric physical information encryption in 3D space. d Experimental results of dislocation-encoded asymmetric encryption and decryption in the PMN-PT crystal. The specific parameters for information encryption and decryption are detailed in the Methods section. Scale bars: 20 µm.
