MotionCAPTCHA – Drawing-Based Captcha With jQuery

Captchas are usually hard to use and boring. However they help a lot in minimizing headaches on the application-side by making sure that "an action is performed by a human".

MotionCAPTCHA, a jQuery plugin, offers a different type of captcha by asking the users to draw the shape displayed. It is not only different but also fun and can even be easier to-use for touch devices.

The project is currently a proof-of-concept considering the captcha is only verified on the client-side and can be manipulated. However, the next version is planned to have server-side and better browser support. Looking forward to it!

    Nick, dummy fields can be manually fixed in the bot script. Captcha cannot.
