NuCaptcha offers a better way to filter bots from humans with a moving text capture technology.

NuCaptcha is a better and more flexible way to keep bots and algorithms from accessing Web sites. With the free, Google-owned ReCaptcha service, 25 percent of humans are filtered out, generating collateral damage. According to Ron Moravek, COO of NuCaptcha, the replacement technology displays moving text against a moving image, making it harder for computers to discern text from background. For humans, this makes reading the text easier as we use relative motion as additional information that helps us see patterns, not as noise to be processed out. The captcha text can also be shortened down to only three characters, saving time and effort in processing the information. NuCaptcha is currently offering a free default option, while enterprise clients can opt for the paid or advertising-supported versions.
