Re: alternate captcha ideas?

I appologize if this is mentioned in one of the links presented in a
response to this post. I assume so but don't hve time to check those links
till later.
But one solution that is very comfortable, to me as a user, is to pose a
verbal problem the user has to respond to such as "what do you get if you
add five to three", of course I realize this is firstly reliant on the fact
the user speaks English (but if this is on an English language web site that
should be fine, if not the question could be stated in the relevant
language) and secondly one could write code to circumvent this to some
degree by figuring out all possible word and number combinations, however
one could also write ocr software to figure out texts in a picture or sound
file, so I think this strike a good balance, at least for a web site whre
security is not absolutely vital and does not keep highly personal or
financial information about the user.
I know there is a company that provides these solutions directly, or
relevant software, and I can track it down if desired.
Again, apologies if this has already been mentioned.

Being that the issue is still far from successfully resolved it is far from
an old topic.
