What Is A CAPTCHA Anyway?
I don't like CAPTCHAs! What is a CAPTCHA anyway?
First of all, CAPTCHA is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart." It is a program that protects websites by generating tests that only humans can pass. CAPTCHAs prevent automatic form submissions. For example, only humans and not computers can read distorted text or numbers.
We must type letters or digits from a distorted image that appears on the screen to prove that we are human.
CAPTCHAs are not limited to letters and numbers. CAPTCHAs may also include other tests. One might have to identify an object that does not belong in a particular set of objects, locate the center of a distorted image, or identify distorted shapes.
The first choice for a CAPTCHA is visual. However, if a person cannot see the CAPTCHA, he can use the audio device provided. If at first you don't succeed, try another image, and another image if necessary.
I don't think CAPTCHAs were designed to make my life miserable. I know they are useful. The test is supposed to be simple, but I declare I cannot read some of those letters. Sometimes it takes me at least three tries to prove that I am human. If I can't read the CAPTCHA, I use the audio device. Sometimes I can't hear that either. Often this is not a speedy process.
I know CAPTCHAs are useful, but I still don't like them.
