Ingenieure demonstrieren ein neues Verfahren, das Daten in natürlicher Wärmestrahlung „versteckt“ und so eine verdeckte Kommunikationsmethode schafft, die kaum abzufangen oder zu hacken ist

Happy Monday r/science! Sharing this study our researchers have published that details a new process for sending sensitive communications by making signals blend into the background of natural heat radiation, like what you would see with a thermal camera.

The study has been published here if you would like to check it out: https://www.nature.com/articles/s41377-025-02119-y

The process harnesses a phenomenon known as ‘negative luminescence’ to create a hidden signal using a special device called a thermoradiative diode. The diode can switch output quickly between brighter and darker-than-usual states which creates a pattern that blends into the usual background ‘noise’ and is therefore invisible to anyone not aware that data is being sent.
