"Enjoyable captcha experience"
Really, I mean REALLY.?
Proof, if it were needed, of the deluded world PR people live in.
Love to see the results of the accessibility study they did prior to creating/releasing this.
What, you mean they didn't do one?
So much for the accessible web, huh...
Just given that a go, and have come away unimpressed. The slider has 30 possible positions, and it gives you a margin of error of +/- 2 on the slider, so there are 5 positions that correspond to a pass. So, overall, the chance of guessing the test is 1 in 6.
Unless there are ways of increasing the number of slider positions, or easily making multi-slider tests, then 1 in 6 is just not good enough.
Didn't some research say that computers were actually better than humans at passings the current CAPTCHA tests?
If they intend it to be used with images containing text or logos, it won't work as a captcha. Aligning and warping images so they're straight is something that machine vision systems do really well, e.g. Scantailor
Looks like most of the images have a horizontal part to the image so just check that while the sliders being moved, or at pure guess as Fraz points out you've got a 1 in 6. Captcha's are already easily broken by adjusting the image, this is just straightening out an ad!
Even without image work, positions 1 to 3 won't likely be usable as they'd count as a pass without moving the slider, and probably the same for the end positions 28 to 30 gives you just 5 positions which could be used to pass.
Seems to work well and obviously easier to use but its not going to stop it easily being broken.
It's a good idea in principle, image recognition is the one thing the human brain completely leaves software in the dust over for now. But it depends on having healthy sight, not much use for blind folk. And I'm pretty sure I'd be pissed off with 'fixing ads' endlessly just to post on some piss-ant forum..
This! The slider position is handled through a hidden form field "adscaptcha_response_field" on form post. It would take less than 30 seconds to write a bypassing hack for it. Whoever thought this would be a good idea has no understanding of web security and risks thereof at all. Adding complexity to it in a way you describe and not make it appear absolutely riddiculous would be nigh impossible and would just end up resembling similar CAPTCHA solutions we've seen before (pattern matching, image interpretation,... you name it, it's all been done before).
There is not even 100 points on the line porbably not even 50, that means if the site doesnt include a limit, it would be very easy for a bot script to choose a value and repeat the test until its at point 20
Well that's assuming you get the same test 20 times and that it doesn't penalise you for repeated failures.
As snootyjim allured to, current captcha codes, the scanned word and the known word, are digitising millions of books whilst you punch them in, so it's not a waste of time anymore, it's actually a genius idea, but does require those few seconds to punch in.
Enjoyable - really ? Imagine your online banking page filled to the pixel with ads
It's amazing how often I fail the 4 letter CATPTCHAs for Hexus competitions and other things. Often times I am 100% sure I've got it correct and I'm pretty sure I'm not being retarded so no idea what is going on there...
