Specification for bypassing CAPTCHAs using blinded tokens
by Alex Davidson 31 Dec '16

31 Dec '16

Hi everyone, I've been interning at Cloudflare for the past 3 months and have been working on developing an implementation of the blinded tokens spec that George and Filippo developed a while back. We've updated aspects of the original spec, the newest spec can now be viewed here: https://github.com/cloudflare/challenge-bypass-specification. We're happy to hear comments from any of you on the design and on the capacity of the solution for preserving anonymity. We've managed to build a test copy of the protocol along with an extension that carries out the required operations. The extension is not completely finished yet, but we're looking towards making that open source as well when it is done. Thanks, Alex

Welcome to the tor-access mailinglist!

Howdy everyone, Welcome to the tor-access mailinglist. This mailinglist is meant to be a semi-moderated forum to engage in solution-oriented discussion about ways to address issues that users have while using Tor (and similar shared-IP systems) to access websites - particularly CloudFlare sites, but also any other major site or provider that currently limits access from Tor for various reasons. If you're getting this mail, you should be able to post to the list freely. Others may also subscribe, but their posts will be held in moderation until we decide to whitelist them. The list archives are public. The list is only moderated so we can prevent it from degenerating into the counter-productive flamewars that have happened elsewhere in these discussions. I intend to be fairly liberal with adding new folks to the discussion, and if everything seems to go smoothly, I will likely turn off moderation entirely. I'm hopeful that as we make progress on these issues, all of that pent-up frustration from seeing one too many captchas will evaporate, and everyone will be much happier to work with eachother :). We've also got a fairly good initial selection of friendly people here: several Tor folks, CloudFlare folks, EFF folks, friendly cryptographers, and other allies are already subscribed. Here's to a positive solution to these issues, and a more accessible Internet for everyone! -- Mike Perry
