[nfbcs] Accessible CAPTCHA

[Peter Donahue]

Hello Ryan,

    Check the ASP and ASP.net documentation for a captcha solution 
particularly those which don't require user interaction. Remember audio 
captchas work for the blind but not for the deaf-blind or those with severe 
hearing impairments. My wife has normal hearing but was unable to understand 
the audio on many captchas due to its poor quality.

    If you find capcha solutions for ASP and ASP.NET like I described above 
please share them with us particularly if it's something similar to CFForm 
Protect.

Hello, Peter,

Since this is a replacement for the client's current site, for the first
phase of the project, we are building the site in classic ASP as a
placeholder as we build an ASP.net 2008 version which will be the ultimate
finished product.

Hello Ryan and everyone,

    Is the site being developed using Adobe's ColdFusion. There is a utility

called CFForm Protect that does all spam control in the background and
requires no user interaction. Learn more at:
http://cfformprotect.riaforge.org/

    The Towson system still cuts out the Deaf-blind as it uses audio.
Perhaps your company is crying wolf. I wouldn't include any spam control
utilities on your forms unless it truly became a problem. It has happened
where developers told clients they needed to use captchas of some kind on
their Web sites only to discover they were unnecessary in the first place.
Why burdon visitors with this junk when it really isn't needed. Whatever
system you use don't shut anyone out!!

Hello,



My company is working on a feedback page for a new client website, and we
will most likely need to use something CAPTCHA-esque to avoid it being
overwhelmed with spam.  I did a little research and found an article in the
January 2009 Braille Monitor reviewing an address given at our 2008 National
Convention from Dr. Jonathan Lazar from Towson University concerning
something called HIPPUU, which, in testing, was significantly more
accessible and effective than standard and audio CAPTCHA's, for both blind
and sighted.  Has this technology come to fruition, and if so, where can I
find it to present to my managers?



Thanks,

Ryan Stevens
