PCMag Features a Facial Recognition System Using a Wink or Smile

Featured by PCMag | March 16, 2021

PCMag featured research led by Brigham Young University professor Dr. D.J. Lee exploring how intentional facial movements could add another layer to a facial recognition system.

In the article “Face Unlock Can Be Made More Secure With a Wink or a Smile,” writer Matthew Humphries examines an authentication method designed to recognize both a user’s facial identity and a specific facial action.

Adding Intentional Motion to Face Unlock

A traditional facial recognition system can determine whether a face matches an enrolled identity. However, recognizing the correct face does not always establish that the person is alert and intentionally requesting access.

The research featured by PCMag explored a method that requires the user to perform a previously selected facial movement, such as a wink, smile, or lip movement, during authentication.

Combining facial identity with intentional motion helps add context to the verification process. The system is designed to evaluate not only who the person is, but also whether the individual is actively participating in the access request.

How the Facial Recognition System Works

During enrollment, the user records a short video containing a distinctive facial action. The system analyzes characteristics of both the individual’s face and the selected movement.

When the person attempts to authenticate again, the facial identity and motion must match the enrolled information before verification can succeed.

This approach was developed as a concurrent verification process, allowing identity and motion to be evaluated together rather than as two separate steps.

Why Intent Matters in Biometric Authentication

Biometric authentication methods commonly rely on physical characteristics such as a face, fingerprint, or retina. These characteristics can help establish identity, but some methods may not confirm whether the user knowingly approved the authentication attempt.

Requiring a deliberate facial action introduces an element of user intent. It can also help distinguish a live, participating individual from a photograph, mask, recording, or unintentional authentication attempt.

From University Research to AuthentiFace

The research led by Dr. Lee and doctoral student Zheng Sun helped establish the foundation for AuthentiFace’s continued development of facial motion authentication.

AuthentiFace is advancing this approach for identity verification across digital applications and physical access environments. The goal is to help organizations verify the individual behind an access request while creating a fast and intuitive experience for the user.
