Brilliant idea but no explanation about how it works, not the slightest hint and no before-after-pics.

Will you stick eyes closer together, stretch noses and mess with other face geometries so nobody takes selfies anymore?

Curious.

EDIT: Ok, I think I know what they do, my first guess:

They change/normalize/randomize the proportions and geometry of the face + make the pic blurry. Look at their team fotos at https://www.deidentification.co/#team where their faces don't look normal.

They slightly alter distances between (and dimensions of) eyes, eyebrowes, nose, mouth, chin and other face features that it's harder to identify faces.

The questions is if this works with pictures shot from other than frontal viewing angles and if users want to put such pics on sites with public exposure like LinkedIn, FB or Instagram.
