Image word verification is a special system where we take a random string of
characters then create an image containing the random characters and display it to the visitor,
then ask the visitor to enter those characters into a text box.
The purpose of this system is to prevent automated systems, also known as "bots", from posing as
a human and posting spam submissions using the web forms.
To use the system, simply type the characters you see in the image into the text box
provided below it. |
