Works even if the fake is pixel-perfect (since it looks at the facial "wireframe" rather than the image itself). The obvious downside is you need sample data of the subject (and usually tons of it).

Siwei Lyu (in the article) did a bunch of work in this space. Also see Hany Farid and Shruti Agarwal. They've worked specifically with deep fake detection. https://arxiv.org/abs/2004.14491
