Abstract

A Game Based Graphical Password Authentication System to Prevent Shoulder-Surfing

Highlights

Passwords are widely being used by the users to protect sensitive data from being misused or stolen
The use of alphanumeric passwords has a problem, even though existing system has different password policies to measure the strength of the password and provides stringency in keeping passwords user’s find it difficult to remember them
Since people adopted with graphical passwords number of methods are proposed for providing authentication to user’s

Summary

INTRODUCTION

Passwords are widely being used by the users to protect sensitive data from being misused or stolen. The use of alphanumeric passwords has a problem, even though existing system has different password policies to measure the strength of the password and provides stringency in keeping passwords user’s find it difficult to remember them It is a tradeoff between Stringency and simplicity, further if the user keeps predictable patterns such as their name or date of birth or most commonly used words it is a lot easier for the attacker’s to crack them. In this paper we have introduced a concept of graphical authentication scheme which works like a game to deceive attackers mind The advantage of this method is user won’t be clicking on the pass image directly, we have added a feature called time where within that limit user has to authenticate otherwise the permission will not be granted.

PROPOSED SYSTEM

Registration phase

Pattern selection phase

Authentication phase
