Put your glasses on: A voxel-based 3D authentication system in VR using eye-gaze

Due to the current push of social Virtual Reality (VR) apps and mobile VR headsets, users are surrounded by people in real life and virtually. Users need a private method to authenticate payments or login into apps. In this paper, we propose VoxAuth, a novel voxel-based 3D authentication system, allowing users to input their password in a private way. By using eye-gaze as a secure, input method, people outside VR are prevented from observing the pass-word. Sunglasses on the avatar appear during the authentication process both as a gaze observation prevention and as a signal that the user is still connected.
