To enhance data encryption and storage, a new, innovative technique has been developed by IIT Delhi. The technique was used on a polymeric material called Cyclic Transparent Optical Polymer. This material can hold inserted charges for extended periods, making it possible to write information at the nanoscale in the form of charges. These charges can only be read using Electrostatic Force Microscopy (EFM), ensuring a high level of security. The technique is versatile and can be applied to various...
