iPhone X Face ID fooled again by 'evil twin' mask


"But can they do it ... without the owner being present while creating the mask?"

You don't need to make a clay mask on their physical face.

You (literally) can glean much 3d information from a single photo inferred through shading and reflectivity. And with more photos, including side shots, allows further reduction in error.

This puts anybody with publicly available photos at risk - felons with mug shots on record, actors, models, politicians, Mark Zuckerberg (https://www.theverge.com/2017/9/18/16327906/3d-model-face-photograph-ai-machine-learning), Mr or Ms anybody with a bunch of photos on facebook.

But still, the victims would need to be targeted with planning - it's not a huge risk for someone who phone got pick pocketed at random.

Write your passcode on a piece of paper in ink that only shows up when you illuminate it with your UV pocket pen lamp, and keep that piece of paper in an obscure corner of your wallet.
