Captchas text is kept server-side in a session variable, thus remaining unavailable to hackers.

The script uses image caching with IP attribution for better server performance without compromizing security.

Size, color, complexity : the captchas are fully customizable.

Be careful though! Keep in mind that there is no 100% reliable method to distinguish bots from regular users.

The best way to control what happens on your website is to keep your eyes open.
