DAP PLXENT#x1D107; : Develop pair-Authentication Protocol with DAP

In today’s interconnected world, secure authentication is crucial for both high-security environments and everyday interactions. Traditional authentication methods like passwords and biometrics are designed for individual use, but new challenges emerge in interactive gaming, theme parks, and collaborative virtual reality (VR) where multiple participants must authenticate collectively. This study introduces a multi-person authentication that leverages cooperative actions to enhance security. By analyzing synchronized sensor data from cooperative actions, the system ensures the presence and consent of all participants, making impersonation difficult. We propose a pair authentication using inertial sensors during a complex handshake known as Dignity And Pride (DAP). Our research evaluates the accuracy of pair authentication, the impact of behavioral degradation over time, and resistance to attacks. Experiments with university students demonstrate high authentication accuracy and robustness against time degradation, though vulnerabilities to spoofing attacks were identified, suggesting areas for improvement in secure cooperative authentication.
