A Captcha is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine. A common type of CAPTCHA requires that the user type letters or digits from a distorted image that appears on the screen. This component based on kaptcha library and produce following HTML code: span id="kaptcha1" class="ck-kaptcha" img id="kaptcha1_kaptcha" class="ck-kaptcha" src="..."/ input id="kaptcha1_input" class="ck-kaptcha" type="text" name="kaptcha1"/ /span so you can change the design by cascading style sheets by the "ck-kaptcha" class. To use this component, you need the chenillekit-image library in you classpath.
