Re: Making A Better CAPTCHA For the Visually Impaired And Making Captions More Available To The Hearing Impaired

I don't mean to be contrarian here, but there are number of problems with
the math problems and other 'simpler' CAPTCHAs.

Effectively, the "if you are a human, tell me what 0 + 1 equals" puzzle
provides absolutely no security against a computer attacker, because computers,
as we know, can do simple addition. Those computers could then spam to
create hundreds of thousands of accounts or comments, thus rendering the
system essentially useless for any human, disabled or otherwise.

I'd like to say that it's unlikely that tomorrow we will wake up and
CAPTCHAs will be gone. In fact, that would probably be a bad thing, because
computer automated spam machines could then essentially shut down large
parts of the internet (email, facebook, twitter, comment sections, forums
... etc).

I think the more realistic and feasible approach is to improve CAPTCHAs and
try to make them more accessible. Simply wishing they were gone won't help
make the internet more accessible.

Also, Jon, have you tried my alternative here <http://t-oss.com/puzzle.php>;?
Do you think the audio is more understandable in this puzzle?
