THE AI ANGLE
Enhancing intercepted electromagnetic signals into legible text and video

Researchers built DeepTempest, an artificial intelligence system that reconstructs on-screen video from electromagnetic radiation leaked by HDMI cables. The software reduces signal reconstruction errors by 60 percent to produce readable text. Engineers and security teams must account for side-channel radio leakage even in wired video setups.
