When I first created my Heyes Captcha I thought I was onto a winner but I must admit it got ripped to pieces by the security community and was hacked in a matter of hours. But I'm persistent so I released another one with a similar outcome :) but now I think I might have created a technique that is fully accessible and also strong enough to resist a computer attack.
The new idea displays the words in a random order and you have to place them in the correct order to produce a valid sentence. I've only included one sample sentence but the idea would be to produce a lot of different sentences and only allow them to be used once. Take a look at the demo below and see if you can arrange the sentence in the correct order.
I've updated the captcha to make it more usable by displaying larger select boxes and changed the code slightly to improve performance. Thanks to Whiteacid for all the excellent suggestions.
More sentences are now included to give a better idea on how the CAPTCHA works.
I've launched another new version which is database powered now. The idea with this one is it takes 2 related sentences and mixes up the second one. It still needs work because it produces too long or short sentences but I think it is getting there.
