Hello Gary:

     I don't know if Dr. Lazar from Towson will be at the convention, but he
and his students have come up with a unique CAPTCHA.
The user is asked to press the space bar when a certain sound is heard. For
example, the user is asked to press space when they hear a train. The user
then hears a sequence of sounds such as a cat, horse, glass breaking, train
etc. the system seems to work.

Regards,

Robert

Subject: [Nfb-web] Captcha Alternatives

Hello everyone,

    This whole issue has caused me to seek out alternatives to captchas and
the problems they cause for all Web site visitors. Being a ColdFusion
developer I was delighted to discover a utility called "CFForm Protect." 
This plug-in does its work behind-the-scenes and requires no user
interaction removing the need to deal with traditional captchas and the
accessibility issues they create for the blind. To learn more about CFForm
Protect visit:
http://cfformprotect.riaforge.org/

    To see a demonstration of how it works visit:
http://www.nfb-writers-division.net/blog

    We currently have CFForm Protect running on the blog and will role it
out to other interactive components of this Web site in the coming months.
I'll also be installing it on several other ColdFusion sites I'm creating or
will build in the future. Want to give it a go? Select the link to the blog
post and leave a comment. In your comment type more than six URLS, enter
words and phrases such as free music download, or Viagra and see what
happens. In the future CFForm Protects capabilities will be enhanced by
linking it to Akismet and Project Honeypot.com.

    One idea I suggested to control spam while not locking out blind Web
surfers is to find a utility that will compare a would-be spammer's IP
address with those of known spammers and preventing that spam bot from
entering data in to the form. Project Honeypot does exactly that! The IP
address of an entity attempting to fill out a Web form is compared with
Honeypot's extensive database of IP Addresses of known spammers. If a match
is not found the entity is allowed to fill out the Web site form. If a match
is found the entity attempting to fill out the form is prevented from doing
so thus protecting the site's owners from spam bots. Working with CFForm
Protect Project Honeypot gathers flagged form entries belonging to would-be
spammers and adds their IP addresses to its database. Hence we can do a
little community service as well as protecting our Web sites from spam bots
all with out creating accessibility barriers for blind computer users! 
Project Honeypot is a free service.

    Akismet is a paid service that can determine if the entity filling out a
Web form is a spammer or not. If it flaggs the entity as a spammer it
notifies the site owner so they can take further action.

    My discovery of CFFormProtect has me wondering if there are similar
plugging, components, and utilities developed for other Web development
environments: ASP, PHP, ASP.NET, ETC. Perhaps this is a matter for our
Webmasters and the IBTC to explore and gather information about these
products and services. Whenever someone seeks our help to make their Web
site accessible we can recommend the installation of one of these programs
instead of captchas and the problems they create for blind and deaf-blind
computer users. Just thought I would spread the word.

Subject: [gui-talk] will Webvisum be rendered useless?

Hi Ken here.  I read in Kim Komando's email that firefox has started a new 
schedule they will be new versions of the browser every too months.  I just 
got the update automaticly today and they are recommending you install it 
since no more updates will be made for version 4.  So in two months for 
example version 6 or maybe 5 point something or other.  Webvisum has been 
disabled since it isn't updated.  the firefox browser says it will enable it

if it has an update.  But can webvisum possible keep up with a two months 
schedule?  is our capcha solver useless thanks to this new timetable by 
firefox?
