How can I set up a knowledge based authentication for my drupal sign up?
not sure how you would pull this off for a registration since the database wouldn't contain any data about a user yet. However one can utilize http://drupal.org/project/password-reset for creation of a kba style password reset.
The other day I came across a forum which on signing up asked difficult maths equation questions in order to join and I thought that is a good idea to get rid of human spammers unless they were particularly good at maths.
For mine I want to ask a question that only locals would know the answer to and in that way would mean no need for manual authentication.
math captcha is included in the captcha module @ http://drupal.org/project/captcha . for questions see http://drupal.org/project/riddler which is an addon module for captcha
well did you see my other post? hope someone knows why riddle is not allowing more than one riddle to be answered, I mean it is allowing but not implementing it.
I figure if I put two riddles on my reg form that should do the trick against spammers :)
