If someone asked what is the Captcha Code, then my simple answer would be that it is such a means that it works like a security check and crossing which is not possible in favor of a machine or robot. In this way, it is such a technique that a difference can be made between humans and machines. It was first brought to the world in 2000 by Luis Von Ahn, Manuel Blum, Nicholas Hopper, and John Langford, who was a professor at Carnegie Mellon University. So for your information, let me tell you that the full form of CAPTCHA is a Complete Automated Public Turing Test To Tell Computers and Human Apart. What is Captcha Code?Ĭaptcha Codes or CAPTCHAs are tools that we can use to differentiate between which users are real and which are automated users, such as bots. I always used to think that why they do not show those alphabets directly so that the user would be easy to solve them. I have tried to solve these Captcha Codes for hours. I can say these things with such confidence because I too have faced all these difficulties. Sometimes there is a lot of confusion in lower case L and number 1, upper case O and number 0. Whenever you have signed up for a new website, application, or have commented on an article, you must have been asked to enter some numbers and crooked alphabets.
