In 2009, Google acquired reCAPTCHA, which you could describe as a spin-off of the original CAPTCHA we just mentioned.Īlthough there are over 20 prominent CAPTCHA vendors today, Google’s reCAPTCHA is the most widely used solution. With the explosive growth of the Internet in the early 2000s, CAPTCHA became a popular way to stop bots from signing up for email accounts and other online services. A lot has changed since then, including the intelligence of cyber threats. CAPTCHA quickly evolved into a method to prevent other types of automated attacks, such as ticket scalping and blog comment spam.ĬAPTCHA was invented over 25 years ago. It was designed to stop bots from submitting URLs to search engines. The CAPTCHA test was first introduced in 1997. That’s not to say that reCAPTCHA didn’t have its time in the spotlight. Believe it or not, this is precisely what’s happening with reCAPTCHA today. Even the most groundbreaking technologies need to retire and eventually make way for better solutions.
