C-Auth: Exploring the Feasibility of Using Egocentric View of Face Contour for User Authentication on Glasses

Published: 08 October 2023 Publication History

Abstract

C-Auth is a novel authentication method for smart glasses that explores the feasibility of authenticating users using the facial contour lines from the nose and cheeks captured by a down-facing camera in the middle of the glasses. To evaluate the system, we conducted a user study with 20 participants in three sessions on different days. Our system correctly authenticates the target participant versus the other 19 participants (attackers) with a true positive rate of 98.0% (SD: 2.96%) and a false positive rate of 4.97% (2.88 %) across all three days. We conclude by discussing current limitations, challenges, and potential future applications for C-Auth.
