BlinKey: A Two-Factor User Authentication Method for Virtual Reality Devices
summary
A two-factor VR unlock that combines blink rhythm + pupil-size adaptation as a single “blinkey,” captured by an eye tracker and classified with k‑NN. Implemented on an HTC Vive Pro with a Tobii eye tracker, it reports average EER 4.0% with 6 training samples, average login time 9.6 seconds, and >93% success on first attempt. False-accept rates fall to zero when blinkey length reaches 7–8, and the scheme resists shoulder‑surfing, statistical forging, and credential‑aware attacks.
