The U.S. Patent & Trademark Office (USPTO) has recently published a continuation patent from Apple showing possible improvements to Face ID biometrics in relation to users wearing masks.

The proposed solution leverage heat maps to assess the occlusion of key landmark on a user face (by wearing a mask, hand in the way, scarf, hat, glasses, etc..). The solution leverages the heatmap to estimate the location of landmarks on a user’s face and may help the biometric algorithm to make a successful identification.
