Captcha is a computer program or system intended to distinguish human from machine input, typically as a way of thwarting spam and automated extraction of data from websites.

JV-MathCaptcha is a free Joomla 3.x captcha plugin that challenges the user to provide the result of a randomly given mathematical operation using addition and multiplication operations on numbers. This is typically used in forms where form data will not be processed if the user does not get the result of the operation right.

The plugin is extremely easy to use, and has a couple of simple configuration options. It should not take more than 5 minutes to download, configure and get it up and running!


  • Admin can decide the type of operation - Addition or Multiplication or a combination of both
  • Admin can decide on the complexity level - Simple/Medium/Complex

Like any other captcha plugin, it attaches itself to a form automatically, and is processed upon form submit.


  • Joomla 3.x
  • PHP 5.4+
