You don’t know what captcha is? Have you seen the colorful words or numbers that most websites ask you to enter when registering or logging in? Yes, this is the so-called captcha image that is actually an acronym: Completely Automated Public Turing test to tell Computers and Humans Apart. Internet Captcha is a free tool that creates very colorful animated captchas that you can embed in your web site to limit traffic to people and exclude other computers or the so-called bots. The captchas it creates use number codes with distortion, animated effects, and background objects that make them impossible for computers to read.

With the detailed wizard like interface you will be able to create captchas in three easy steps. First, there is the Visualization, where you choose the background and number colors and the size, thickness, and movement of the numbers. The user is also able to add simple icon like background images and set their speed. In the Security step set distortion levels, distance between numbers, maximum spin of the animation, and doping elements via level adjusters. Finally, the Code Resulting step generates a code in ASP or PHP that can be copied and embedded easily. A preview panel along the bottom displays your captcha as a work in progress, depicting various effects as you add them. A thermometer like display will rate your security choices.

The program’s web site offers documentation and information, but this tool is basically self-explanatory since you can observe the result of every change you make. If you are concerned about the access to your web site, here is a free-and-easy solution.
