Dear all.
I am hoping for a bit of a shortcut by posting this, rather than
leafing through the WCAG 2.0 standard, because I guess some of you may
have dealt with this situation before.
An Icelandic government web site has put captia on every single load
of the web site (the web site is that of the superior court and they
claim they are protecting the privacy of the individuals in the court
cases from internet searches).
Their captia is completely inaccessible, and nothing on the site can
be activated without having to fill in the captia first.
The government has committed itself (not legally, but in its official
information society policy document) to W3C A compliance .. which I
take to mean WCAG 2.0 Level I compliance, it is never explained
further.
Which part of the WCAG standard does inaccessible captia break?
Does anyone have experience in writing about this before (a letter of
complaint or legal statement of any kind)?
Anything of that nature you can share would be very helpful.
Thank you very much and have a great day y'all.

Under 1.1.1 Non-text Content: All non-text content that is presented to the user has a text alternative that serves the equivalent purpose, except for the situations listed below. (Level A)
CAPTCHA: If the purpose of non-text content is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities.

Our software engineer found a transparent captcha. I don't know much
about it, but seemed like a perfect solution both for accessibility
and usability.

So now NO ONE can see the word provide the answer! :)
Seriously, what's a transparent CAPTCHA?

Agree, I have a hard time imagining it.

"what is 2 plus 5, write the number here"
type ones

I just talked with the software engineer and we are using more of the
spam protector, that is coldfusion specific
http://cfformprotect.riaforge.org/
If you type in transparent captcha into google, Wordpress seems to
have several entries.
Sorry for the misinfromation

there is one site that I've come across where the captcha is actually
readable and the user is asked to retype it in to another box. I found that
it can be selected and then copied to the box as well.
