“We look at your face and generate a formula looking at stable features of your face that will describe your face and produce a one-way hash result of… where there is interesting information in your face. And when you apply your unique formula to your face, what would the results of that formula look like as expressed in a hash.”
That’s very different btw than the way normal biometrics work, where they’re basically taking a picture of your face vectorizing it, and saving it out. But it’s still reversible…
