Code Hitmen

Overview

This is a module for the Drupal content management system that enables the use of the Asirra CAPTCHA system. Asirra was created by Microsoft Research as a more robust implementation of the ideas found in KittenAuth, as well as a more tasteful CAPTCHA than HotCAPTCHA. It uses images from Petfinder.com to weed out automated robots and spammers.

The module is loosely based on the existing Drupal CAPTCHA module -- however, there are significant differences in the internals of asirracaptcha compared to the CAPTCHA module.

Download

You can download the current version of the module here.

• asirracaptcha-0.1 -- Drupal 5.x version
• asirracaptcha-0.1 -- Drupal 6.x version

Installation

Simply unzip the archive into your modules directory, enable the module, and then set up the forms for which it will be used by going to the "Asirra CAPTCHA" page in the "User Administration" menu.

Limitations

The client JScript code (hosted by Microsoft Research) for displaying the images doesn't work correctly if the CAPTCHA is displayed more than once on a page. As a result, if you have the CAPTCHA enabled for multiple forms that are displayed at the same time, it won't work correctly.
