Maybe it can't work.

Hi, there exists a problem, if we verify whether a user is human or bots in browser, bots can simply ignore the CAPTCHA and send packages the same as a human who passed the CAPTCHA.

Not only that, but a bot can take hold of the DollarRecognizer instance and redraw the templates precisely. The templates should be server-side, along with the recognizer itself.

Wouldn't that be the case with ANY client-side captcha/ verification? You always want a server side validation to double check.
