Does anyone have good alternatives to old/new ReCAPTCHA? I've been scratching the surface of academic research in the area, and it's all kind of messy.
(It's no great secret that CloudFlare would love to switch away from ReCAPTCHA, for a whole variety of reasons. It's one of the things Tor users complain about the most, but it's an issue for a lot more users than that. We're doing a lot of stuff to reduce reliance on CAPTCHAs overall throughout 2015, but we still need a good one for some checks.)
I wonder if some kind of prize (anti-Turing prize?) would help. There's the core algorithm/approach question, as well as the infrastructure and deployment model question. I'm a lot more comfortable answering the latter; the former is a black art mixture of science and art.
