Facial feature analysis for authentication

A system comprising:

• an image capture device to capture an image of a portion of a face of a user, wherein the user is wearing a facemask;
• a display device;
• a processor;
• memory, including instructions, which when executed by the processor, cause the processor to:
• retrieve, based on identification information, a registered 4D model of the face from a database;
• receive a user selection of a facial feature, the user selection comprising an eye mannerism comprising an eyebrow movement;
• determine whether the user selected facial feature matches a preselected facial feature of the registered 4D model;
• in response to determining that the user selected facial feature matches the preselected facial feature, compare the portion of the face in the captured image to the facial feature of the registered 4D model;
• in response to determining that the portion of the captured image matches the facial feature of the registered 4D model, grant access to the user to secure content, wherein the registered 4D model comprises the eyebrow movement, wherein capturing the image of the portion of the face includes capturing the eye mannerism performed by the eyebrow movement, and wherein determining whether the user selected facial feature matches the preselected facial feature includes determining whether the eye mannerism corresponds to the eyebrow movement;
• and
• output an indication related to the secure content for display on the display device.
