For Smarter Authentication, We Might Need to Use ...
summary
Evaluates brainwave authentication using 14-channel consumer EEG with 52 participants and stimulus tasks (oddball P300, N400, priming, faces). Achieves an equal error rate of 7.2% EER (previous consumer work 22–26%), but at a practical operating point of 1% FAR yields about 22% FRR—usable for low-security or hands‑free/VR scenarios. Reports real-device pipeline, channel-reduction to ~9 channels, a released dataset, and strong usability/privacy concerns (headset setup, speed, “mind‑reading”).
