Do I need to create a database table to implement captcha on a registration form?

+4  A: 

Have you considered using reCaptcha rather than implementing your own system? There is a Ruby library available although I haven't personally used it.

It also has a ruby plugin.

Even if I use recaptcha or any other third party plugin, do I need a table to match the captcha code with what the user enters as an answer?
With recaptcha, you don't. see http://github.com/ambethia/recaptcha/blob/1b8c52017467a1ae19397320615b63387cef03ba/README.rdoc
