CAPTCHA!

I am looking into using a captcha to make it safer for users to sign up to Project Hours Time Tracking.  This component voor MVC will do the trick: https://github.com/tanveery/recaptcha-net

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart  and is designed to determine if it is a human or a bot that is trying to logon (only humans allowed of course)..


Google's reCAPTCHA is easier  for users than the old images with distorted characters..


The user only has to tick the box to verify she/he is not a robot. How does that work? Robots can also very easily tick boxes, automated UI tests do this every day. Apparantly, Google analyzes the user's behaviour, i.e. the way the cursor moves, and is able to determine whether it concerns  a human or robot. More explanation in this stackoverflow thread: How does the new reCAPTCHA work
