GPC: Graphical Pen-based CAPTCHA
I know I’m a little behind, but here is the new web application for the month of May. It’s a start of a system I implemented as a final project for a class I took this semester (6.870.) This is a pen based CAPTCHA system, where you trace over shapes to conduct the Turing test. I also have an associated paper that talks about it in more detail, I will fix it up a bit and upload it here when it is done.
