Captcha 508 Compliance
Recently when I was creating a contact us web page, I ran into an
issue with 508 compliance. Generally, to make a site 508 compliant you
have to sacrifice certain functionality to achieve this goal. However
there is one area where this functionality cannot be sacrificed and
this is in the use of a Captcha. Captchas are absolutely necessary when
creating a website that allows user to submit comments, questions, or
payments. However in general captcha's are very difficult to read even
if you have 20/20 vision, are sometimes impossible to read for the
color blind, and are obviously impossible for the blind using readers
to understand. .
Now there are many types of captchas some that ask simple questions
and others that ask you to pick the correct image, but this still does
not address the issue for the blind. So after doing some searching
around I found an open source captcha plugin that allows you to use it
as your captcha but the nice thing is that it also has a sound
component that supports four languages and can read off any code you
provide it. After hacking out the sound component out and integrating
it with the captcha being used for the site, it worked beautifully. The
example provided in the source made it easy to understand how to use it
and how to integrate it with my own captcha. I highly suggest it if you
are looking for a sound component for a letter/number based captcha. I
am sure there are other good solutions out there for captchas with
sound but this definitely suited my needs. http://www.titude.nl/scripts/demo/captcha/
