• 論文抄録(英) / 内容記述: With the increasing number of spatial computing and LiDAR-enabled mobile devices, 3D spatial mapping has enabled novel security applications. In this work, we propose WorldAuth, a LiDAR-based authentication method that leverages the unique 3D geometry of a user's room as an authentication factor. We implement our system entirely on an iPhone, capturing room geometry via the built-in LiDAR scanner and representing the scene as a point cloud. We evaluate several point cloud registration methods and similarity metrics, including ICP, FGR, and learning-based approaches, to compare genuine scan pairs and impostor scan pairs. Experimental results across diverse environments demonstrate promising performance, achieving an F1-score of up to 0.8558 and an Equal Error Rate (EER) of 0.0432, even under moderate changes in viewpoint and scene clutter. A user study complements the performance evaluation by assessing usability and real-world feasibility, suggesting that real-world-based authentication is both intuitive and privacy-preserving on modern mobile devices.
