Enhance authentication security by registering strange faces?

With the spread of facial authentication, it became convenient that there was no need to remember PIN numbers and passwords. Face authentication, such as Apple’s Face ID, is known as a very advanced technology as a security tool to accurately read the shape of a user’s face in the TrueDepth camera system.

For example, it is a strong system that cannot be authenticated if you hide a picture of your face in front of the camera. But there are loopholes. Research shows that having glasses on the face of a sleeping or unconscious person can unlock facial recognition.

What was suggested to solve this problem is facial authentication. In English, it is a new two-factor authentication called Concurrent Two-Factor Identity Verification (C2FIV). According to a research team at Brigham Young University, registering strange faces that can be reproduced increases security. It allows you to read two things: facial structure and subtle facial muscles. When registering face authentication, you have to register your face several times, but if you register with a slightly different movement each time, the point is that you can remember a slightly different appearance in the system.

To test this new algorithm, the research team produced 8,000 video clips, including 50 subjects winking, making smiles, and raising eyebrows, and trained them on a neural network. As a result, it is said that it was possible to grasp the movement of the face with a rate of 90% or more. The research team plans to use it for more neural network training.

Strange face authentication increases security even more because the owner has to make a strange face when someone else wants to unlock the smartphone. But what’s good about Apple’s Face ID is that you can unlock it in less than a second just by aiming your smartphone at your face. If you register a strange face, it will take longer than now because it unlocks it compared to the cloud server. It takes a little more time to make a strange face in front of someone to enhance security. Related information can be found here.
