The “T” in CAPTCHA is for the famous Alan Turing, who is considered the “father of modern computing.” Turing, who died in 1954, developed a test as a way to examine whether machines could think like humans, and if people could tell the difference. The father of computing gave birth to the idea. However, the actual term CAPTCHA is attributed to the four-man team who were the creators of reCAPTCHA, which was a Captcha-like system bought by Google in 2009. The idea for the graphical CAPTCHAs used today was described in detail in a 1997 priority date patent application by a handful of men in 1998. It generates and grades tests that humans can easily pass but are impossible for computer programs to solve – like having to type the scrambled or distorted words and letters inside a picture (or voice recording for the visually impaired).
