SUZUKI Keita, a fourth-year student in the Department of Frontier Media Science, School of Interdisciplinary Mathematical Sciences, received both the Interactive Presentation Award (PC Recommendation) and the Interactive Presentation Award (Audience Vote categories) for his work titled “Overlay QR Code Attack Using LED Displays” at INTERACTION 2026, the 30th symposium organized by the Information Processing Society of Japan.
The PC Recommendation Award is selected by the INTERACTION 2026 Program Committee, while the People’s Choice Award is determined through votes from all participants of the conference.
This research proposes a new disguised QR code attack using LED displays. By applying the superimposed QR code attack — which exploits the difference between human visual perception and camera imaging characteristics — to LED displays, the constraints on code modification that existed with LCD displays are removed, enabling more flexible tampering and further strengthening the attack.
