Hi, I work as a researcher for a large company that develops these CAPTCHAs for some of the biggest websites on the internet. You have 100% visited a website we protect.
My job is to create exactly the algorithms that distinguish human-and bot behaviour alike.
Yes, we analyze your mouse movements. Yes, we analyze your activity on the website, we take into account the IP you use, the browser, and much much more.
Bots are able to replicate human-action at very large scale very fast. They can scrape your entire website, stealing your intellectual properties, they can brute force you login page, effectively hacking into people’s accounts. They can even bruteforce credit card forms and steal your money.
These captchas force the bots the replicate more of the human actions, blocking most of them, and slowing others.
I’ll be happy to answer follow up questions 🙂
