A CAPTCHA is a test used to identify humans, by asking questions that a machine would have a hard time answering. For example, you've probably seen things like images with scrambled letters in them when you fill out forms online. A lot of times, these things are really hard to read, even for real people. I get them wrong all time.
When I developed the challenge response system at Spam Arrest several years ago, that was how we kept that spam out. I also created an audio-version, which spoke the letters that the person needed to type, so that sight-impaired people could pass the test. But it still wasn't very user-friendly.
A competing product, by MailFrontier, had a cute variation on the test where they showed a picture of a number of cats, and asked "how many cats are in this picture"? It was always 1-5, and there were only cats in the pictures, so it was pretty easy to guess at or to hack with really basic image processing, but it was much friendlier of an experience.
I always thought it'd be cool to do something similar using tagged images from flickr. Today, I found a couple fun/funny variations on that idea.
-
Identify Cats and Dogs (Microsoft Research Asirra Project). Cute, using pictures from Pet Finder....
- Hot Captcha (Pick the "HOT" girls or guys, from HotOrNot data). Offensive to some I'm sure, and purely subjective/cultural, but an entertaining idea...
For accessibiliy, I think some should do an animal sounds one ("what animal makes this noise? (play MEOW)") too..
