The same way any highly regulated company does when ID needs to be 100% confirmed
Put on today's news/put up today's newspaper/generate a unique, time sensitive code the person needs to write down and display, have them take a picture while holding up ID and the date proof using a live webcam.
But when authoritarian people want other people to do things, they generally don't think about how much effort it takes, or if it does take effort it is brushed off as if nothing with no concept of cost benefit. It's easy when you just shift the burden of proof by making vague insinuating statements to appeal to the majority of the population which is highly emotive.
You'd better hope their ID/webcam matching software (or employee) isn't racist. Why are there no dark-skinned people on your platform? Oh, turns out they're all held up in ID verification…
