Captcha was once cutting edge technlogy in the fight against spam, but not anymore. These days the systems are being cracked regularly, with Google, Microsoft, and Hotmail among the victims. Now, a 3D-based Captcha system claims to be both unbreakable and easier for humans to solve than the old text based systems.

The system was developed by social website Yuniti.com. It works by asking users to identify 3D objects rather than words or numbers. There are three objects to be identified and the list is endless, making it even harder for scammers to guess correctly.

This seems like an excellent idea. The current Captcha have lost most of their effectiveness. The ones that do still seem to work often frustrate legit users, and the last thing you want are potential customers leaving your site in disgust because the Captcha image they need to solve is too difficult to decipher. This costs you business and can lead to negative word of mouth among other potential customers.

You can try the new 3D Captcha at Yuniti.com. There’s no word yet on when it will be available for widespread use.
