CAPTCHAs are "completely automated public Turing test to tell computers and humans apart" commonly used on websites to make sure the submission of content is being done by a human and not a robot (and sometime even just to access content). The main implementation right now is Google's ReCAPTCHA which can be viewed as "working for free for Google" which a growing number of people are having problems with.

It would awesome to have a captcha technology that improves the commons instead of improving a company.

A paper by Stefan Keller talks about ReMAPTCHA for this problem https://wiki.hsr.ch/StefanKeller/wiki.cgi?ReMAPTCHA but the code is unavailable. Maproulette seems similar in certain ways.

Would it be possible to adapt maproulette for this kind of use ?

  • having an "anonymous" usage (no need for registration)
  • providing a iframe/js widget to do this task
  • probably have a way to put changes in an "incoming" queue that is checked by OSM contributors

By the way kudos for the excellent work on maproulette ❤️

Hi @arthurlogilab, I haven't had a chance to read the paper yet, but off the top of my head you might be interested in #367 (suggested fixes), which seem like they'd be more friendly to a captcha-style workflow
