Ironclad CAPTCHA

Why should I use it?

Almost every web site on the Earth that contains some form to allow visitor register, login, or to submit some information, suffers from spam. There thousands of robot programs that surf the Internet and fill in the forms to promote their sites, post unsolicited advertising or even compromise web sites they visit.

If you own some forum, blog, social networking site or a site with registration/login procedure, you know that spam can easily kill every good project in the matter of days.

The most effective measure against spam is to require user pass some test, often called CAPTCHA (Completely Automated Public Turing Test to make Computer and Human Apart). In most cases user should enter some letters or numbers or words he sees on picture (which is screwed, crossed by lines, noised, etc.) to pass the test and then he'll be allowed to submit form.

Bad news: All conventional CAPTCHAs are aready CRACKED. There are programs that can recognize your current CAPTCHA with 80% accuracy which means that your site WILL be spammed anyway.

Even current Google and Yahoo CAPTCHAs are already cracked (this rumored to be impossible for a long time, but not today). Though there are programs that can recognize them only with 35% accuracy, it is still enough! It just means that robot will try three times in average before he succesfully submits his spam.

Ironclad CAPTCHA is DIFFERENT.

Why do you call your Ironclad CAPTCHA "unpenetrable"?

Because it is unpenetrable. Nobody can crack it today, and nobody probably will in next 10 years. Instead of asking user to enter letters and numbers (which even real human sometimes can't recognize, but computer already can!) we show him a picture with several primitive objects like teapots, keys, balls, and so on.

Ironclad CAPTCHA is rendered in realtime from 3D scene, where each object can be positioned, scaled, rotated and colored in random way. We then require user to count the number of three given types in the picture to pass the test.

This is the task that even a kid can accomplish! But not computer. In image where there are a lot of objects which can't be determined by their shape (because the shape can change dramatically when the object is scaled and rotated), by their color (different objects can have similar colors and several objects of one type can have different colors) and can't be segmentated (because objects can intersect, overlap, etc.) computer raises its virtual hands and gives up!

Wow! But can I use it for my site? Is it free? Is it reliable?

Absolutely! You can use it for free for any site, even if it is commercial and even if it is popular and has a lot of traffic - our capacities are high and we can handle almost any load and deliver Ironclad CAPTCHA to your site in any circumstances.

When we say that you can use Ironclad CAPTCHA on any site, there are however some exceptions. We DO NOT accept sites with adult content, gambling, advocating terrorism and discrimination of any kind. If your site doesn't fall into one of these categories - you are welcome!
