Non-Intrusive Intellectual Gaming CAPTCHA for Optimal Web Security

Abstract

In the era of excessive internet usage, a turing test is required to oppose various attacks on websites by differentiating machine based activities from human. So, by concerning the security of a webpage; a CAPTCHA is tentatively very useful in the form of deformed text, mathematical, OTP (One Time Password), Audio, 3D, Graphical and Gaming CAPTCHA. CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart which is a test to identify whether the interacting user is human or a robot. Among various implemented techniques Gaming CAPTCHA is one of the highly secured CAPTCHAs which is trending now.

A CAPTCHA should be as easier as human can solve within few seconds that would be almost impossible to solve by robot. Here, the proposed system is able to provide better level of security as compare to the existing CAPTCHAs. Proposed game possess high graphical interface along with attractive interaction that can inspire users to solve it without any annoyance. Proposed game requires speech based object recognition along with some logical moves that unhide input fields. Game has various AI problems at different phases that turn it more intellectual as compare to the earlier one. The motive of the system is to provide best level of security that cannot be cracked and able to replace the existing systems.
