No captcha recaptcha."tick" .I am not a robot.

Google moves to replace "nocaptcha"

[Leosghost]

A survey in 2012 suggested humans found more than 90% of Captcha tests difficult. But computers have got better at them and can now solve an estimated 99.8% of them, Google says.

So it has altered the system. No Captcha ReCaptcha, being rolled out from Thursday, simply asks desktop computer users to tick a box saying "I'm not a robot". The actual tick is not important, but the human behaviour involved - such as the imprecise movement of the mouse before and after clicking and the time taken to solve the problem - is. Computers find these hard to replicate.

Great, if it works.

Here's the Google announcement on the idea.

One of my little jokes that I wheel out from time to time is to exclaim "Damn, that CAPTCHA is so hard, I think only a computer could solve it."

Because that's what it's come to. I find honeypot solutions, Bad Behavior and proof-of-work methods to be as effective against bots, if not more so, while being invisible to human users.

Their mobile-friendly option reminds me of this: [bbc.com...] ... because if they can scale the image recognition then the finite amount of images they rotate can grow, making it harder to just store all the permutations.

For mouse movement, no doubt 'natural' movement will be unique to each site due to the layout, bit of text to be read etc. Seems like it'll be cracked before long though.

Time for spammers to work out the degrees of freedom a wrist can move and some trig to arc their mouse movements...
