Exciting news! Our submission to ACM ASIACCS 2024, entitled “The Catcher in the Eye: Recognizing Users by their Blinks” has been accepted for publication. Congratulations to Iijima-kun and the team!
BlinkAuth leverages unique blink patterns and electro-oculogram (EOG) data for user authentication, with an impressive average accuracy of 95.2% and a usability score of 82.50. This innovative technology has been extensively tested under a variety of conditions and shows remarkable robustness to environmental changes and potential security threats. Get ready to explore the future of secure and efficient user authentication!

Suzuki-san presented a talk at EuroUSEC 2023, which is held in Copenhagen. We got excellent questions/comments from the audience. In this study, we introduce “PinchKey,” a novel VR authentication method leveraging the natural ‘pinch’ gesture. Here’s a snapshot:
Intuitive & User-Friendly: Replaces traditional methods like pattern locks or PINs, using the VR-familiar pinch gesture.
Technical Insight: Uses a supervised machine learning model to analyze the 3D trajectory of the pinch gesture for authentication.
Tested on Meta Quest 2: Our evaluation with 29 participants showed an impressive average AUC of 99.7% and a swift average authentication time of 1.65 seconds.
High Usability Score: Achieved a top-tier system usability scale (SUS) score of 86.25.
Real-World Ready: Demonstrated resilience against potential threats.
In essence, PinchKey offers a seamless, accurate, and rapid VR authentication experience. Watch out for its wider adoption in the VR realm!
