Security is a constantly changing industry. That's why we have a team of people at NuCaptcha dedicated to monitoring the current security situation and tuning the platform accordingly.
One security feature of the NuCaptcha Security Platform is the Animation System. This helps NuCaptcha to be both the most secure and easiest to use Captcha system available.
Another security feature is our Behavior Analysis System. This gives easier Captchas to legitimate users and progressively more secure Captchas to attackers.
NuCaptcha also employs captcha best practices to help ensure our Captchas are secure.
NuCaptcha uses patent-pending next generation animated Captcha technology. Testing has shown that animated Captcha puzzles are easier for humans to recognize and solve than static, scrambled Captcha images.
Compare the static images on the right, MEA and TEX, to the live NuCaptcha. These are actual screenshots of a NuCaptcha video stream. Notice that the animated NuCaptcha is much easier to read.
When the letters are moving your mind sees the different parts and fills in the blanks; the parts that are moving together are grouped together, and you can clearly differentiate the letters. Computers don't have this advantage and see a smear of pixels.
We're often asked how NuCaptcha is displayed. One common assumption is that it is rendered in Adobe Flash.
NuCaptcha is displayed as an H.264 MPEG-4 Video Stream that is rendered in your browser in a variety of ways.
It's important to note that NuCaptcha is a video stream and not a Flash program. This is because it is not secure to create a Captcha in Flash.
The vast majority of visitors to your website are legitimate users. So why punish customers with a conventional Captcha that presents static garbled images that are difficult and frustrating to decipher?
The NuCaptcha Security Platform is different. It uses a behavior analysis system to monitor all interactions on the platform. It then uses this information to tune the security of each Captcha delivered to each user.
Legitimate users are given easy to solve Captchas, and attackers are given progressively more secure Captchas. This maximizes usability for legitimate users; eliminating frustration and increasing conversions on your website, while providing a high degree of security against attackers.
The examples to the right appear difficult to read as static images, but of course are still very easy to read for humans when they are animated.

On the surface Captchas seem fairly easy to create. But there are many challenges in creating a secure Captcha system.
Below are some best practices for security features to be aware of when evaluating Captcha systems.
