A couple of captchas

A couple of neat captchas designed to go beyond the traditional warped letters and random sums. For those not in the know, captcha stands for completely automated public Turing test to tell computers and humans apart, and it’s that step you have to go through sometimes when you buy tickets, add comments etc.

First of all, asirra from Microsoft Research. Basically, you’re presented with a picture of nine cats and dogs, and you have to pick out the cats. Apparently, asirra stands for Animal Species Image Recognition for Restricting Access. (I wonder if they’re going to offer me a fortune to buy my domain name off me.)

And then there’s Hot Captcha, the same concept, but with attractive and unattractive women/men (you can choose).

Great concept.

    Imagine if you saw your own picture up there, and you basically had to say you were minging in order to prove that you weren’t a robot. This is how witches were treated in the middle ages you know.
