Clever. Not knowing the details of how computers beat CAPTCHAa can you explain why it would be difficult to create a program to trace the path?

- StavrosK 14y agoI don't think it would, really...
- barik 14y agoI've done some research in this area with examining user input mechanics. This particular example would be solvable using B-spines [1], as one possible approach. The "path CAPTCHA" even provides some great computational hints, by indicating the starting point as a circle! http://mathworld.wolfram.com/B-Spline.html http://mathworld.wolfram.com/B-Spline.html
