Re: [EXTERNAL] Re: CAPTCHA Update--Providing CloudFlare Reference

With apologies, I should have searched further before writing my earlier message.

Here’s the explanation of the scheme based on zero-knowledge proofs.

Thank you, Janina. Here’s the more detailed, technical treatment of the proposal.
https://blog.cloudflare.com/introducing-cryptographic-attestation-of-personhood/<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fblog.cloudflare.com%2Fintroducing-cryptographic-attestation-of-personhood%2F&data=04%7C01%7Cjjwhite%40ets.org%7Cbaf3e67086b94161073408d99fb6a0f7%7C0ba6e9b760b34fae92f37e6ddd9e9b65%7C0%7C0%7C637716429008415324%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=Btp%2ByHWd7P%2BxVc1PzEAdnnLKEWPWkXNCHdwuowNHlik%3D&reserved=0>

Note also the suggestion toward the end of the article that a zero-knowledge proof-based scheme is also contemplated, with details forthcoming.

We’ll need to consider updating the CAPTCHA note accordingly. Is the following process in accord with your understanding of what is needed?


  1.  Revise the Note and obtain appropriate review.
  2.  Republish as a Working Group Note, if approved at a Call for Consensus.
  3.  Request elevation to W3C Statement status.
Regards,

Jason.

Colleagues:

Here's the ZD Net article about Cloud Flare's desire to kill CAPTCHA I
