How to use the Captcha?
All you need to do is type the characters appearing in the image (below the text box) into to the text box.
If the image characters are not clear to you – you can always click the "Can’t read it" link, and picApp will replace the image with a new one.
What is a Captcha?
In a CAPTCHA test (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart", also sometimes spelled in lowercase), an image of letters is dynamically generated. The letters, because they're part of an image and not text (not text that you could cut and paste), are difficult for a spambot or other computer program to read. Still, a person has very little trouble reading the letters in a captcha image.
Using a captcha test on a website is a great way to ensure, for instance, that a person and not a program or robot is filling out a web form for purposes like spam or creating a denial of service attack on the service servers. Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm the form's purpose.
