Light-Induced Entropy for Secure Vision This cover illustrates a secure imaging system that counters deepfakes using light-induced hardware security. Upon capturing a scene, the photodetector simultaneously generates a unique physical random number, embedding a watermark directly into the image. This ensures immediate authentication, distinguishing “Real” captured moments from “Fake” manipulated content at the hardware level. More details can be found in the Research Article by Byung Chul Jang, Young-Joon Kim, Hocheon Yoo, and co-workers (DOI: 10.1002/adma.202516947).
