Ask HN: User friendly Captcha systems for mobile apps?
Hi,
I'm looking for a captcha solution that is as user-friendly as possible for a mobile app. Couldn't find anything interesting.
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.
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.
Thanks!
- pavel_lishin 10y agoGoogle's "Select all the pictures that are of flowers" seems like it would be well-suited for mobile.
- yonilevy 10y agoThat's a pretty good solution, but I can't find a way to ask Google for that specific challenge (it seems to be bundled with other challenges that are web-oriented). Is there a way to do that?
- pavel_lishin 10y agoI'm not sure, I've never used it :/
- Vexs 10y agoI think it auto-detects mobile, I've never gotten one that wasn't click-the-flowers.
- zodPod 10y agoI always get the one that is like "select all of the storefronts" and I screw it up consistently. I end up having to go through like 20 pictures before I'm verified because I choose things that look, to me, like storefronts but, apparently, aren't?
- Freak_NL 10y agoAll the while feeling as if you are part of a massive unpaid labour force training Google's optical recognition algorithms and adding and verifying Google Streetview metadata (e.g., “select all images containing street signs/store fronts/lakes”).
- doublerebel 10y agoOh we definitely are. Best way to get this kind of information into a database is by socially engineered human map-reduce.
- dutra 10y agoWhat about implementing something in the likes of https://github.com/josscrowcroft/MotionCAPTCHA https://github.com/josscrowcroft/MotionCAPTCHA ? I think this would be user-friendly for mobile users.
- shthed 10y agoCan you use reCAPTCHA? Nothing easier than just ticking checkbox "I'm not a robot".
- ahoka 10y agoAs far as I know that check-box works by analysing the mouse movement when you check it. I don't think that would work on a touch screen.
- simbalion 10y agoThe 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.
- angryasian 10y agoOn 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.
- yonilevy 10y agoBut how do you know it's not just a random string?
- angryasian 10y agoI think it depends on what you are trying to accomplish with the use of the captcha.
- anthonys 10y agoValidation 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. 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.
- rezashirazian 10y agoThis 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. You send a request to a driver, the driver shows up and confirms the person applying, completing or w/e is actually a person. This can have potential legal/government related application.
