Hi,
I'm looking for a captcha solution that is as user-friendly as possible for a mobile app. Couldn't find anything interesting.<p>Do you know of such a framework / are you working on one? With the many sensors available i'm sure there could be interesting, user friendly ways to make life harder for bots.<p>It seems like the common alternative is to send a validation text message (makes it harder to spam), but that doesn't seem optimal from a UX perspective. Would love to hear ideas from that direction as well though.<p>Thanks!
The best captcha system is no captcha system at all. You might take a look at the Wordpress plugin 'WP Bruiser', which is extremely effective at eliminating bot submissions, without any user interaction at all.
What about implementing something in the likes of <a href="https://github.com/josscrowcroft/MotionCAPTCHA" rel="nofollow">https://github.com/josscrowcroft/MotionCAPTCHA</a> ? I think this would be user-friendly for mobile users.
On mobile is it necessary. I guess its most dependent on what you're trying to accomplish. On mobile you have access to a unique id like device id or other identifiers that are specific to a device.
Validation text messages can be useful and as long as you think about the message (Ie. I can pull the notification banner down and see the numbers rather than have to exit the application I am in), it shouldn't impact the process too much.<p>On Android you can even read the message yourself. It seems iOS can do this too but for now it seems on Apple can read verification messages.
This may fall outside of what you're trying to do, but I always thought the best form captcha would be to extend Uber to do real human to human verification.<p>You send a request to a driver, the driver shows up and confirms the person applying, completing or w/e is actually a person.<p>This can have potential legal/government related application.
