      Biometric data can be copied. Which is usually one of the most important flaw of this form of authentication.

      If someone (or something) steals your biometric data, you cannot change it.

      I would be much more convinced by a cryptography based solution where you can create a token on some separate hardware device and have to give a secret PIN to authorize it’s creation. Then that token would prove for a time that you are indeed a human. No AI can read your mind so I suppose that’s the safest way to prove your human… Until your PIN gets stolen by an AI somehow…

      I hope most governments around the world will provide cryptographic certificates to their citizens to help them manage their online identity.

        This does already exist on a blockchain, but people hate shitcoins so it’ll likely never take off until the tech gets subsumed into some centralised Web2 service. Account access by a human and an account with a bot that’s been delegated access by a human have two different states being noted. A developer can implement a gate that requires a fresh physical unlock to get in.

        You can, at least for now in some small way, accomplish this through use of hardware security tokens. Maybe not for long, but at least it’s something.

        Which is where I though the real use of nft 's would come in. Its a shame there just associated with crap generated images now

          I’m not sure to follow what an NFT would bring to the table to solve this problem. I think an AI could create a NFT just as well and pretend to be human.

          Also blockchains are usually pretty slow so minting a new NFT everytime you need to prove you are human would probably be unpractical.

          The more I think on this problem the more it looks challenging. Almost anything digital could be forged by an AI in some way.

          The only thing might be a problem only an human can reasonably solve and so it ends up like captchas. And captchas are notoriously weak to AI now.

          I’m not sure there is any easy way to identify a human from a machine. If there is a way it will almost always need the human to solve a complex problem everytime which will be very annoying.
