Introduction:
reCAPTCHA is a security system provided by google to prevent websites from spam and fraud as you know that there are different bots and humans crawl on web pages at a time. reCAPTCHA detects that whether the bot is present on the website or human beings. Humans can solve reCAPTCHA, but bots cannot solve it.
There are three versions of reCAPTCHA. In the first version, a complicated text or word is present to which humans have to enter to get access to the page. In the second version, an image with cars, traffic lights, and fire hydrants are present. Humans have to choose similar pictures to solve this reCAPTCHA.
