New 'negative light' technology hides data transfers in plain sight
Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that's hard to intercept. Using a phenomenon known as "negative luminescence," the system works by making signals blend perfectly into the background of natural heat radiation, such as can be seen with a thermal camera.
Australian engineers have developed an innovative way of sending hidden information that is difficult to intercept. Using a phenomenon known as "negative luminescence", the system causes signals to blend perfectly with the background of natural thermal radiation, leading to a new alternative for data encryption.
Researchers hide data in heat radiation. New infrared technology makes communication practically invisible. The post Secret Communication: Engineers hide data in heat radiation first appeared on ingenieur.de - Job market and news portal for engineers.
How does 'negative light' hide data?
Using thermal emission as a covert channel Engineers have demonstrated a communications method that conceals data inside ordinary heat radiation by exploiting a phenomenon called negative luminescence. Instead of broadcasting a distinct optical or radio signal that can be easily detected, the…
