Review my photo CAPTCHA web service

By what measure is peoplesign more secure? You have 6 choices in 2 menus -- even a robot that is completely stupid will pass 3% of the time.<p>I know that in the past some captchas were broken at rates of 30-40% (Hotmail, I think). Is this really still the case?

I downloaded the PHP plugin, and applied for a private key to use the service. The key came immediately, and I've already added the captcha to my site So far I am impressed. <a href="http://www.backwardsparadigm.com" rel="nofollow">http://www.backwardsparadigm.com</a>

Very cool idea. It does seem faster than most captchas I've used. Would be cool to have the option of only one image, and be able to choose the answer in one click instead of via a drop-down menu. That would make it really fast (though probably less secure)

Looks easier to read than most CAPTCHAS, though I suppose that you have to speak english to get past it. Could be a good way to learn a language :)<p>Has this stood up to any bot attacks yet? What's the significance of the image discoloration?

If you draw the labels onto the image (make them each one word) and make the user type them, it's still an easy captcha for a person, but much harder for a bot.<p>If this spreads, it will be worth making a bot for, so that you can spam any of the sites that use it -- right now that bot just needs a few hits on average, and a slightly smarter bot can space them out, so that they are conceivably like commenters.

This is nice but too big for most forms that use captcha (comments, feedback, etc...).

Remove the word "arguably".<p>You're marketing. Not the time for balanced language.

This is too hard. Why don't you have some boxes that you can drag and drop to?

I found a misspelling in a label for a plane image. (The correct selection was 'striped plan' or something like that.)<p>Also, what turned out to be a hydrant looked to me like the leg of a moon lander. (I stared at that thing for a really long time, but I still saw the leg of a moon lander.)
