Audio Visual Reconciliation Intellectual CAPTCHA as New Era of Turing Test

Abstract

In this digital world; security is a significant concern towards access validation that can be computed through some kind of turing test i.e. CAPTCHA. The term CAPTCHA was introduced for classifying credibility of user whether the intervention has been initiated by human or bots. . CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”. It is a fortification tool that denies junk/bots entries in the form of challenging problems. CAPTCHA has been prefabricated in various forms such as alphanumeric distorted strings, 3D strings, picture identifications, gaming problems and many more. The recent approach is gaming CAPTCHA and most of the game may increases the server load towards the browser. The logic behind the gaming CAPTCHA is dealing with dragging & dropping object to the target position, so these CAPTCHAs do not belong to the hard AI problems. The
objective of the paper is to provide better level of hard AI problem that can be solved within few seconds with fewer efforts that challenges bots to solve in a limited time. But proposed CAPTCHA is based on audio video reconciliation where user has to recognize the correct combination of appearance with its sounds. That is why it contains two level security premises, speech recognition with picture identification.
