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.

Dogs 101: thanks for reading and responding. However, a CAPTCHA has nothing to do with dogs. CAPTCHA is used on computers. CAPTCHA is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart."

Yes! *Grins* I detest captchas too, because they are inexcessible for the most part, and sometimes don't even work if you put in the correct answer because the script/code is buggy. They forgot about the visually impaired and the deaf when they came up with captcha, even the audio ones block out the deaf-blind. Some sites thankfully use truly accessible captchas now, in the form of a simpl question in text format that you type the answer to, and all good captchas should never require you to see an image or hear a sound to prove you are a human.
