Google has launched reCAPTCHA version 3 that is a complete overhaul of the reCAPTCHA technology. The company first introduced this background check system back in 2007 and this is the 3rd major overhaul being sent to it. reCAPTCHA itself was initially introduced in 2014.

Designed to ward off bots on the internet, reCAPTCHA has proven to be useful but extremely annoying. However, with reCAPTCHA v3 Google aims to reduce this annoyance by no longer requiring any user interaction. No more squinting of eyes to read garbled codes or clicking on images of billboards.
