C-Auth是一种新的智能眼镜认证方法，它探索了通过眼镜中间的向下摄像头捕捉到的鼻子和脸颊的面部轮廓线来验证用户身份的可行性。为了评估这个系统，我们在不同的日子里对20名参与者进行了三次用户研究。我们的系统在所有三天内正确地验证了目标参与者与其他19名参与者（攻击者）的真阳性率为98.0% (SD: 2.96%)，假阳性率为4.97%（2.88%）。最后，我们讨论了C-Auth当前的限制、挑战和潜在的未来应用。
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.
