At the 110th CSEC and 60th SPT Joint Conference, held from July 7 to 9, 2025, Fukuchi Lab delivered one oral presentation.
In this presentation, we introduced a novel spoofed QR code attack technique that leverages a high–refresh-rate display. By exploiting the gap between human visual perception and camera imaging characteristics, the display appears to a viewer to show only a legitimate QR code, while a camera is deliberately placed in a probabilistic state where it decodes either the legitimate code or a malicious code.
