Cloudflare releases Privacy Pass 2.0 extension

Internet company Cloudflare launched the Privacy Pass extension for Firefox and Chrome back in 2017 to reduce or even eliminate the number of captchas that Internet users are exposed to.

Captchas may be displayed on websites as a form of verification to ensure that the visiting user is a human being and not a bot. Cloudflare operates one of the latest networks on the Internet that many sites use for protection against DoS attacks and for various other functions.

If you connect to the Tor network or VPN networks regularly, you may have noticed that the number of captchas that you are need to solve to access sites increases significantly over regular Internet connections. One of the main issues is that the regular system does not take into account previously solved captchas. If you visited a site and solved a captcha, you may still be asked to verify another one on another site.

Privacy Pass has been created in collaboration with researchers from several universities to bypass captchas without sacrificing privacy in the process.

Privacy Pass, in a nutshell, allows clients to provide proof of trust without revealing where and when the trust was provided. The aim of the protocol is then to allow anyone to prove they are trusted by a server, without that server being able to track the user via the trust that was assigned.

Basically, what happens is that users get tokens in advance that may be used later on to bypass captures that would otherwise be displayed.

A simple visit to a captcha page could fill up tokens to 30 which would then be used automatically when compatible pages are encountered that require additional verification.

Cloudflare launched Privacy Pass 2.0 for Firefox and Chrome on October 28, 2019. The new version makes the extension easier to use, integrates a new service provider (non Cloudflare), and improves the technology used by the extension.

The, rather technical, post on the Cloudflare blog provides detailed information on the new version.  One interesting new feature is the unlocking of the extension for other services. Cloudflare revealed that a new version of the extension will roll out soon that supports the provider hCaptcha.

Internet users who solve a captcha provided by the provider will receive tokens if they run Privacy Pass that will be used automatically on other sites that use the provider's captcha solution.

Closing Words

The new version of the extension won't convince users who distrust Cloudflare to give it a try. Users who run into captchas, especially those by Cloudflare, regularly, may benefit from it as it should reduce the number of captchas that they are exposed to.

Now you: would you use something like Privacy Pass?

    Can you trust the CloudFlare DNS server? What the best server DNS OpenDNS, GoogleDNS, ComodoDNS or OpenDNS?

      Comodo spies for the British. Not trustworthy. Why do you think they give away so much free stuff!

    Sounds promising, hate captchas! I wonder how it plays well with resistFingerprinting and other addons like Privacy Badger or Chameleon.

    “would you use something like Privacy Pass?”

    I have to dig into the technical details to see how private this really is. If it actually seems to protect privacy (even from Cloudflare), then I might use it. My gut tells me that’s doubtful, but I don’t really know with any degree of confidence right now.

    I’m getting this right? At first they locked sites behind captchas to “reduce” traffic and protect them from suspicious behavior and then they released an extension that solves captcha on these locked sites and at the same time they’re saying its a safe solution while Google captcha itself can be used to track users? What keeps them from tracking users who decide to use that extension?

      One of the ideas behind the extension is to award users who pass a check once with tokens that may be redeemed in future checks.

    “The new version of the extension won’t convince users who distrust Cloudflare to give it a try.”

    Exactly. Cloudflare told us before that using their DNS was increasing privacy, and the tech press, incompetent or sold-out, parroted them (with few exceptions like the EFF), so that I had to dig in the technical details myself to understand that it was the contrary. This time I am not even going to lose time digging into the complex math and cryptography of this system to check if they have been lying again and if this does allow them to track us, and I’m not going to trust tech press opinions about it: I’ll just stay away from it.
