ThermalTap: Passive Application Fingerprinting in VR Headsets via Thermal Side Channels
Researchers have developed a novel method called ThermalTap that can identify applications running on virtual reality (VR) headsets by analyzing their thermal emissions. This passive technique uses a commodity thermal camera to detect the heat patterns generated by the headset's internal computations, acting as a proxy for application activity. ThermalTap can achieve over 90% accuracy in indoor environments with just 10 seconds of data, and maintains significant accuracy outdoors despite environmental variations, highlighting a new privacy risk for VR users.
