I agree with Janina’s point 1 below. Regarding “completely automated”, I think it a CAPTCHA challenge is only “completely automated” from the Web site operator’s perspective. It’s a manual process for the user (in every instance), whereas for the site operator, no human work need be involved once the system has been installed and configured.

Now that we're again working on updates to our 2019 Note on CAPTCHA, I'm finding some 35,000 foot observations we didn't comment on in previous drafts of this document: 1.) We need to acknowledge that the user performs as the site provider dictates. Whether more or less accessible, the site chooses the work the user is to perform. I would now argue this is backwards. I would like now to suggest that we move toward systems that allow users to choose the technology that works for them. Obviously this would need to be a technology sites could rely on. My point is that users shouldn't have to deal with every variant of CAPTCHA on the planet--which is the case today. 2.) I'm finding myself wondering about the perspective of the inventors of this technology. As our document has always explained, CAPTCHA stands for "Completely Automated Public Turing Test, to Tell Computers and Humans Apart." So here's my question: What part of CAPTCHA has every been "Completely Automated?" At least until Google's Recaptcha 3, this strikes me as a bogus claim that we should have called out long ago. Is a process "completely automated" because it's automated for the server? As thought the human in the process doesn't really matter? How sad a world view that bespeaks!

To answer it directly: > > > > 1. The proposed WCAG 2.2 success criteria 3.3.7 and 3.3.8 didn’t exist, at least in their current form, when the CAPTCHA Note was last significantly revised circa 2019; and they were controversial at that time. They presently remain proposals only, as WCAG 2.2 is not yet in Candidate Recommendation or beyond. We can consider whether to refer to them in a subsequent draft of the CAPTCHA Note, as the proposals are relevant in this context. > > 2. More substantially, it is not clear that 3.3.7 or 3.3.8 addresses the CAPTCHA phenomenon. In particular, if we read 3.3.7 and 3.3.8 in conjunction with the “CAPTCHA” item in success criterion 1.1.1, then it makes sense to interpret 1.1.1 as allowing perception-based CAPTCHA challenges, as long as alternatives relying on different senses are available. One can then interpret “authentication” in 3.3.7 and 3.3.8 as referring only to verifying the identity of the user – and not to determining whether the user is human, which is the distinctive function served by CAPTCHA challenges. In addition, it is not clear that tasks requiring the user to recognize objects or characters in images, spoken words, etc., involve “memorization” in the sense in which this term is used in the definition of “cognitive function test” in the WCAG 2.2 proposal. Thus, WCAG 2.2 is arguably best interpreted as not changing the status quo with respect to CAPTCHA, as established by success criterion 1.1.1 in WCAG 2.0. > > If the intention of the Accessibility Guidelines Working Group is to override the explicit statements about CAPTCHA in 1.1.1, then this will need to be made very clear, in my opinion. The only consistent reading of the draft as a whole at the moment appears to be to interpret 3.3.7 and 3.3.8 as not addressing CAPTCHA, at least of the kind which is expressly permitted under 1.1.1. > > > > From: Rochford, John <john.rochford@umassmed.edu> > > Sent: Tuesday, 28 December 2021 6:29 > > To: public-apa@w3.org > > Subject: [EXTERNAL] [turingtest] Accessible Authentication > > > > CAUTION: This email originated from outside of our organization.
