JNCASR researchers add more security to LiFi

Researchers from JNCASR have added another layer of security to LiFi by coating the walls with phosphorescent paint.  The phosphorescent paint absorbs light and randomly emits photons, which ultimately scrambles the signal by superimposing a larger noise component to the signal. Jamming the signals can even prevent usage. Like WiFi, the light-fidelity (LiFi) technology that uses both visible … Continue reading JNCASR researchers add more security to LiFi
