Implementation of Simple Text Based Shoulder Surfing Resistant Graphical Password using CAPTCHA and VRK

A Higher number of security primitives depend on hard difficulties that are reasonable just by mathematical formulation. Utilization of Difficult AI problems for security has turned into a development for another worldview of security, yet still left underexplored. In this paper, we will recognizably exhibit another security primitive in view of hard AI problems, to be specific, a novel group of graphical password frameworks based on the premise of Captcha technology, which we call Captcha as graphical passwords (CaRP). CaRP is a mind boggling mix of Captcha and a graphical password style. CaRP tackles various security issues altogether, for example, online guessing attack, relay attack, and, if joined with double view technologies, shoulder-surfing attack. CaRP alone gets to be inefficient to keep all security, hence this paper makes a survey of the various security measures for secure password schemes and gives a clear picture of the efficiencies of the different techniques. The proposed system introduces a novel Virtual Random Keyboard and a secure intellectual OTP and LTP technique for securing the authentication at a higher level. Thus the proposed system enables user to securely login without any attack probability by multiple level security and advanced attack preventing mechanisms.
