A secured image based three factor user authentication system

Abstract

Graphical User Authentication (GUA) is an image-based password system that leverages the human tendency to remember visuals more effectively. This methodology enables users to effortlessly generate and recall passwords. The three important parameters for any graphical based password system are Usability, Randomness and Security. Usability deals with the system adaptability, memorability, flexibility, User satisfaction etc. On the other side randomness is about Hotspot Coverage, Click Point Clustering, Spatial Patterns, J-statistics etc. This paper is an attempt to initially develop an image-based authentication system that is usable, venerable in terms of randomness. In addition, it is necessary to build a strong security authentication process where the attackers are unable to access the system. The past research study claims the diversity between the usability and security aspect. The focus of this research study is to analyze the impact of various security attacks on the proposed system and the possible solution to avoid them.
