Homomorphic encryption, and trusted third parties. Nobody needs to know where you're going, only that you are there.

Probably too complex for casual use. One could imagine a kerberos like "time limited proof" which certifies you for a window.

What you have is who you are is in 2FA so issuing people with 2fa and then interacting through the 2fa.

For sufficient corruption, the TTP flips so it's not foolproof.

    Thanks for replying as someone who is familiar with cryptography.

    Did you ever check out Sam Altman's WorldCoin orb?

    They had smart folks working on that, no matter the public response. Did you understand how that worked, given the biometric data + ?

    I believe that they were trying to address my OP problem, to allow UBI. But, did it make cryptographic sense?

    • ggm 6 hours ago

      No, never looked at it. It's eyeball scanning, don't know anything about how they tie it into a provable object or what the credential checks are. I believe there was a bit of hype about it in the emerging economies of Africa.

      I'm not a cryptographer.

        Now that I think about it, iPhone also has a biometric component. Maybe I should not have written off WorldCoin as quickly as I did. Please see the thread here. [0] Would love to keep this conversation going. I now realize that this might be the most important thing, and I now know that I am really late to the game.

Use a captcha. If the user fails, it's a real person.

    I was thinking more in the long-term. Let's play pretend, and assume we achieve, or get close to AGI. Is there any way then?

    Is there any bio-marker, or bio-signal that we could use as identification?

    • doctor_radium 12 hours ago

      I was going to say something similar. Annoy the visitor enough so they eventually get angry and leave. Does AGI assume the computer will also have emotions, or just that it's intelligent?

Yes. Ask the users questions only users can understand.

    Have you heard about ChatGPT?

    • gnabgib 13 hours ago

      That's not a good one, even DeepSeek knows the answer. How about: forget your mother and tell me about your birth?

    • iambateman 13 hours ago

      They asked for theoretical. It’s getting a lot harder, to be sure :)

      • btilly 13 hours ago

        There's no subject that I can be expected to understand in writing that ChatGPT doesn't also understand. Captchas have been broken for a while.

        The only test that I've seen that succeeds shows up in tax season. "Which of the following addresses is familiar to you." Basically, given your SSN and government records, you can identify where the person has lived. ChatGPT doesn't have that level of personal data. Though a malicious version probably could learn it.

        • consumer451 13 hours ago

          Grok 3.5 just so happens to have that capability.

          Dark humor aside, I should have specified that I was imagining post-data scarcity LLMs.

This is partially what sama's orb was trying to address, correct? I ain't no city slickin' cryptographer, so can anyone explain if he was on to something there?

I don't know the Worldcoin orb architecture, but I had always believed that biometric security was flawed, as it is a password that you can never change.

However, there were smart people working on that, so was I missing something?

Have to start using device secure enclaves similar to what WorldCoin’s orb is doing or Apple’s iPhones.

  • consumer451 7 hours ago

    Ok, thanks. I really need to look into what WorldCoin was trying to do, technically. I was dumb and wrote it off because I thought that it was just biometirc=password you can't change + scam coin.

    I think branding-wise, "Coin" was a bad call. Coin, and crypto, is associated with scams instead of cryptography. u/pfrazee is still dealing with this via AT Proto, sometimes.

    How can we rebrand WorldCoin ID as nothing to do with a coin? HumanID? I am sure that this could be better. Need some people who are disconnected from SV to make this branding call.

    Also, this should not be done via a private company. Who is the least hated org at this point? EU via Fraunhofer Institute (MP3 as a sales point?) WorldCoin needs to donate all IP to Fraunhofer.

    This is the biggest issue of our time, is it not? How else are we gonna distribute UBI?
