Latest Patents

Yan Long holds a patent for "Acoustic eavesdropping using a smartphone camera." This invention reveals how rolling shutter and movable lens structures commonly found in smartphone cameras can modulate structure-borne sounds onto camera images. This creates a point-of-view optical-acoustic side channel for acoustic eavesdropping. The movement of smartphone camera hardware inadvertently leaks acoustic information, as images modulate ambient sound into imperceptible distortions. Experiments indicate that this side channel is amplified by the intrinsic behaviors of complementary metal-oxide-semiconductor (CMOS) rolling shutters and movable lenses, such as optical image stabilization (OIS) and auto focus (AF). This disclosure characterizes the limits of acoustic information leakage caused by structure-borne sound that perturbs the point-of-view of smartphone cameras. Unlike traditional optical-acoustic eavesdropping methods, this side channel does not require a line of sight or an object within the camera's field of view. Yan Long's patent represents a significant advancement in understanding the security implications of smartphone technology.
