Today, we’re excited to announce that we’ve implemented a new smart captcha system to protect the data integrity of all forms powered by Wufoo. A captcha is a test used on a web site to make sure that the data being submitted to a form is actually coming from a human and not an automated bot or script. They’re used to prevent abuse and data contamination.
While a number of our users have requested this feature from us for awhile, we’ve been hesitant because a number of studies have shown that when a captcha is used on a form, it severely impacts the conversion rate. This is because it also slows down and turns away legitimate users, who often get frustrated by the extra test.
In an effort to balance the needs of our users who want to insure the integrity of their data with our desire to promote best practices for high converting forms, we implemented a smart captcha system in Wufoo that tries to automatically detect abusive behavior and only show a captcha test in those situations. Here’s a (http://www.flickr.com/photos/wufoo/3682271967/?processed=1&cb=1246574875589) we made to show off the feature in action.
We’re also very proud to be using [reCaptcha](http://recaptcha.net/) to help power our new anti-bot system. They’re used by web sites all over the world and we think it’s great that we’ll also be able to help digitize texts that are being scanned and stored in digital format for preservation and accessibility.
By default, all forms in Wufoo are set to automatic protection, but you can also set the captcha system to always show or never show the captcha on your form as well. You can find this feature’s options under the form settings tab when you edit your form.
