eli5: How do Captcha’s know the correct answer to things and beyond verification what are their purpose?

333 views

I have heard that they are used to train AI and self driving cars and what not, but if thats the case how do they know the right answers to things. IF they need to train AI to know what a traffic light is, how do they know im actually selecting traffic lights? and could we just collectively agree to only select the top right square over and over and would their systems eventually start to believe it that this was the right answer? Sorry this is a lot of questions

Captcha is not really selling an image-recognition product. The whole purpose of a captcha is to stop automated inquiries while still allowing humans to navigate in a natural flow. It’s not an IQ test either.

The images you select, or puzzles you complete, simplifies it all.

captchas actually look at a lot more data. Captchas capture some mouse movements, keystrokes, last page visited, how you entered the website, your browser, attempts made, and some other super secret information.

You see the puzzles because you have a monitor, but a computer doesn’t actually need a monitor, or a display, to browse through the internet. A bot can successfully complete the captcha and still be denied entry to a website.
