CAPTCHA = Completely Automated Public Turing Test To Tell Computers and Humans Apart A CAPTCHA is a type of challenge–response test used in computing to determine whether the user is human. The term was coined in 2003 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper, and John Langford. The most common type of CAPTCHA was first invented in 1997 by two groups working in parallel. They could be easily solved by humans, but they become challenging for machines to solve, therefore preventing programs from abusing online services and occupying internet resources. Using Convolutional Neural Networks, the CAPTCHA tests could be solved automatically at high efficiency. Current approaches of high accuracy CAPTCHA recognition can be structurally complicated. CAPTCHA Recognition As a solution to the automation problem due to a CAPTCHA Bypass, we have developed an API web service that caters automated CAPTCHA solving to solve a CAPTCHA. How it works?
