Abstract
There is provided techniques for two-factor facial recognition authentication of a user. A method is performed by an authentication device. The method comprises performing a facial recognition process. The method further comprises performing a challenge-response evaluation process. There is also provided an authentication device configured to perform such a method. There is further provided a computer program for implementing the two-factor facial recognition authentication of the user.
Claims26
A method for two-factor facial recognition authentication of a user, the method being performed by an authentication device, the method comprising:
- performing a facial recognition process, comprising:
- obtaining, via an image sensor, a first facial image of the user;
- and
- recognizing the user by performing facial recognition on the first facial image;
- and
- performing a challenge-response evaluation process, comprising:
- providing a challenge to the user by playing out at least one media item to the user, wherein the at least one media item is selected from a set of available media items for the user and is associated with a face emotion selected from a set of available face emotions;
- obtaining, via the image sensor, a response to the challenge from the user, wherein the response is a second facial image of the user;
- classifying the second facial image to one of the face emotions in the set of available face emotions by performing face emotion recognition on the second facial image;
- and
- successfully authenticating the user, responsive to the face emotion of the second facial image matching the face emotion associated with the at least one media item.

An authentication device for two-factor facial recognition authentication of a user, the authentication device comprising processing circuitry, the processing circuitry being configured to cause the authentication device to:
- perform a facial recognition process, according to which the processing circuitry causes the authentication device to:
- obtain, via an image sensor, a first facial image of the user;
- and
- recognize the user by performing facial recognition on the first facial image;
- and
- perform a challenge-response evaluation process, according to which the processing circuitry causes the authentication device to:
- provide a challenge to the user by playing out at least one media item to the user, wherein the at least one media item is selected from a set of available media items for the user and is associated with a face emotion selected from a set of available face emotions;
- obtain, via the image sensor, a response to the challenge from the user, wherein the response is a second facial image of the user;
- classify the second facial image to one of the face emotions in the set of available face emotions by performing face emotion recognition on the second facial image;
- and
- successfully authenticate the user, responsive to the face emotion of the second facial image matching the face emotion associated with the at least one media item.
