From PINs to Gestures: Analyzing Knowledge-Based Authentication Schemes for Augmented and Virtual Reality

This IEEE conference talk explores the evolving landscape of authentication methods for Augmented and Virtual Reality (AR/VR) environments. Discover a systematic evaluation of 17 distinct authentication schemes across five categories: gaze-based, gesture-based, PIN-based, spatial, and recognition-based. Learn how researchers from the University of Denver and George Mason University analyzed these methods for effectiveness, security, and usability. Examine findings showing Beat-PIN's impressive 140-bit entropy security strength alongside RubikAuth's exceptional usability with authentication times of just 1.69 seconds. Understand user preferences for balanced authentication approaches like In-Air-Handwriting and Things. Gain insights into promising authentication schemes and future research directions for AR/VR security based on the application of Bonneau et al.'s framework.
