Who created the captcha and why is it there

many of you may hate the captcha but who and why created it and is it possible to turn off the captcha

I think there's a Techquickie episode on it.

I think they were originally used to prevent people for using bots to buy all of the concert tickets available for some large event.

Not sure who made it, but I'm fairly certain it was made as an attempt to stop bots.

No way to turn it off AFAIK.

Captcha is embedded in the website your trying to use. It is to prevent bots. Not only from the deciphering of the letters and characters, but also from messing mouse movements

The newer "I'm not a robot" ones are made by Google. They use a variety of data to determine who is and isn't a bot, most of which is kept confidential to prevent bot-makers from taking advantage of any flaws in it. If the captcha isn't sure if someone's a bot, it shows a "challenge", usually picking images. 

 

My personal suggestion:

After you click "I'm not a robot", move your mouse really fast over the box while it's spinning. Make sure to do random patterns like circles and diagonal lines. It should approve you right away. 

Reason it works is because bots can't do true random movements very well. So if it sees you doing that, it will know you're probably not a bot. 

 

Not 100% reliable, but I've gotten a lot less challenges since I've started doing this (I encounter captchas multiple times every single day because a site I use requires it for login). Used to get a challenge every single time, now I get them maybe 1-3 times a week. 

 

Your findings may vary, as there's a on of other data it uses. 

 

It also looks at your history, tracked via google ads. So if you clear your cache often, use an ad-blocker, or rarely visit websites that use google ads, you will also get challenges more often.

There's no going around one and even if there were, we wouldn't share that info. Catphca and likes are meant for webmasters as a tool to protect their sites. Think it like password or pin code. Might not stop everyone, but will hold most back.
