spambots. We just have to jump out of the existing
band-wagon. Here are some ideas:
Surely we can come up with a creative idea that is:
* Easy for humans to solve
* Can't be solved by out-of-the-box captcha breakers
* Isn't trivial for programmers to solve
I would like to suggest a slight variant on something google's doing
now, that I don't think they got quite right.
Pick half a dozen animals of which there are many specie variants, say,
dog, cat, snake, bird, etc.
Show the user one such animal, and a 3x3 grid with 4 animals from that
species, and 5 which are from the others, 64x64px ought to be plenty.
Ask them to click on all the animals of the same species. Assuming
we can word that in a way that doesn't fail for people who don't know
species are. Without losing the advantages of using pictures by *saying*
"cat", that is.
The key here is to make the evaluation criteria sufficiently clear;
the google implementation seems to require too much introspection into
which characteristics of the pictured object they want you to match.
Once you've captcha'd then, you could, I would expect, put a cookie
on the browser good for some amount of time and hashed against, say,
the browser ID string or something so it's not portable?
