Re: Bad humans ?
Maybe it's better to learn whether or not the problem at hand is even tractable.
Consider the First Contact problem. How can Alice and Bob prove their identities to each other if they've never net before? This is essentially the problem we face every time we register to a new site. We don't really know who runs the site, and the site doesn't know a thing about us.
The thing is, the First Contact problem is logically intractable. With no common point of reference, there's no way for Alice to prove she is Alice and not someone else posing as Alice. Not even Trent can help since Trent can be a double agent and has to be vetted himself, creating a Turtles All The Way Down conundrum. It's a Catch-22. You need common ground to create trust, but you need trust to create common ground.
That's why we can't seem to find a simple solution: because there's no solution full stop. We're just trying to make impersonation as hard as possible, but unfortunately we're stuck for the ride. Making things harder for the imposter makes things harder for US, and there's no way to unlink the two since the imposter's job is to BE us, essentially: right down to the DNA if they gotta. And inversely, easier for us is easier for the imposter. Worst yet, it seems the medium is UNhappy: not easy enough for us but not hard enough to thwart the imposter. So, basically, what now, especially when the public demands unicorn solutions?
