[nfbcs] Captcha

Tue Feb 28 16:40:11 UTC 2012

Well, I've been promoting digital IDs as a solution to the problem.

As a proof of concept, I set up a portion of my web site at 
http://www.johnheim.net/ccso/ for sign-on with a certificate from 
cacert.org. Cacert.org provides free digital certificates. The only catch is 
that you have to have two other people who are already signed up with 
cacert.org to "assure" you. In other words, you have to have two current 
members vouch for your identitty.

If you have a digital ID from cacert.org, you can point a browser to 
http://www.johnheim.net/ccso/ and click the sign-on link. Your browser will 
then ask you to select a digital ID.  Select your cacert.org digital ID and 
you're in. It is 100% accessible to anyone who can use a computer at all, 
costs nothing, and is easy to configure.

I have a dream (fantasy?) of these long lines of blind people at the NFB and 
ACB conventions waiting to sign up to get digital IDs from cacert.org and 
then getting yahoo, google, and the rest to allow them as an alternative to 
captchas. Or  serious sites like yahoo or google could issue their own 
digital certificates.  When you create your account, you would get an email 
with the digital certificate attached and instructions for installing it. In 
fact, I believe the instructions could be as simple as "Click this link". 
But you might want to use the digital ID on other computers so you would 
probably save it to a thumb drive.

The ultimate solution to the problem of keeping out spammers is not captcha. 
There is nothing that most humans can do that a computer cannot. Its just a 
bogus concept in the first place.
