I work in FR. The first PR move when covid hit was to publish videos demonstrating our accuracy with both a medical mask and sunglasses on. The technology still works, with a less than 8% drop in accuracy for single images, and less than 4% drop with motion video.

I assume it's looking at more than faces then? Gait, earlobes, etc.

  Face, head, ears & shoulders, with full 3d reconstruction and refinement via motion video. Np gait, too easily gamed.

    Any suggestions to lower the %? Small prosthetics under mask for nose/cheeks? Does hair bulk affect head shape? Any suggestion for ears? Shoulder pads? I guess there's not a great way to slim features, only bulk, which may be accounted for? Is this currently mainly matching people with their past self's model, or is this also integrated with data connecting us to our identities (for the average suburbanite who doesn't visit locations which scan IDs frequently)

      Can't say much without revealing trade secrets. However, two things one can do to prevent identification via any FR: 1) place a bright LED somewhere near your face, such as on eyeglass frames or the brim of a hat. That bright LED causes a hot spot in the camera frame with an area of glow large enough to obscure one's face. Additionally, many cameras have a physical mechanism that closes an aperture to reduce the light received - that takes a bit less than a second; if the LED blinks at a rate near that mechanism's adjustment time, it will never adjust in time and the entire frame will always be too bright or too dark in alternation with the LED blink. The second thing one can do is draw or place stickers on your face with additional eyes, noses, and/or mouths on your face. Similar to the fantasy/art makeup look where people paint an additional set of eyes on their forehead - the FR will see 6 eyes or 3 mouths and will reject that as being a human face.

What is the alleged accuracy before the drop, and under what circumstances?

And honestly, covid just created a larger dataset of people in the wild with masks and sunglasses. In all sorts of lighting and settings.
