Captcha, which apparently stands for the completely incomprehensible “Completely Automated Public Turing test to tell Computers and Humans Apart”, is a system that asks users to type in words, in order to prevent robot programs from filling in forms. We’ve all come across them. They drive me mad…..
Firstly, more often than not the words we are asked to copy, like those in the image above, are so distorted that I start to think it’s time for a trip to the optician. If this isn’t enough, the words are usually total garbage.
The idea of adding Captcha to forms is to is to ensure that only humans fill them in. But if humans can’t read the words, they won’t be able to fill in the forms which renders the forms totally useless.
