Installing A System With Graphical Password Schemes

Since conventional password schemes are vulnerable to shoulder surfing, many shoulder surfing resistant graphical password schemes have been proposed. However, as most users are more familiar with textual passwords than pure graphical passwords, text-based graphical password schemes have been proposed. Unfortunately, none of existing text-based shoulder surfing resistant graphical password schemes is both secure and efficient enough. Here, we propose 4-D Password scheme to make the existing scheme even more robust and powerful. We propose to different authentication scheme to one system, and this will lend more stability and make the attacks on user privacy even more difficult to succeed in. We proposed a system with graphical password scheme, Color code authentication, OTP based authentication, and Time Elapse Authentication scheme composed as a 4-D Authentication system.

I. INTRODUCTION

Today, although the password authentication is used widely, since users write their password directly on screen and tend to make their password easy to remember, they may be vulnerable to several attacks such as brute-force, guessing, replay, and shoulder surfing. Although many authentication schemes were proposed to improve the usability and security, they are still vulnerable to the shoulder surfing attack. In this project, we propose a 4-D pattern-based authentication scheme which is secure against this attack. Also, we analyse the usability, deplorability, and security of the
