Content-Independent Avatar Ownership Detection for Preventing Sockpuppet-Enabled Violations in th...
summary
AvatarJudger identifies all avatars controlled by the same person using 3D finger-joint telemetry rather than account metadata, claiming cross-device ownership detection with a multi-stage pipeline that combines a random-forest global model and a deep neural net for short-term habits. Evaluation on 2,217 avatars from 30 participants across HoloLens 2, Quest 2, and Vision Pro yields >94% accuracy, finds pink noise in 90% of signals, highlights left-hand fingertip–wrist distances and 44 stable features, and notes time drift and reliance on hand‑to‑keyboard input.
