What is CAPTCHA | Definition and Meaning

CAPTCHA stands for Completely Autonomous Public Turing Test to Tell Computers and Humans Apart. CAPTCHAs seek to identify bot traffic by making a test that most humans can pass but that computers currently cannot. CAPTCHAS therefore prevent the bots from interating with apps designed for human use. The founders of CAPTCHA avoid using the term “Reverse Turing Test” or (RTT) to describe CAPTCHAS due to the inaccuracy of the description. However, some academics refer to it as a reverse turing test regardless. CAPTCHAS are not designed to be forever unbreakable, and the founders of the CAPTCHA believe that computers will be at least as good as humans in time.
