A SURVEY ON SHOULDER SURFING RESISTANT GRAPHICALAUTHENTICATION SYSTEMS

Abstract

Authentication based on passwords is used largely in applications for computer security and privacy. However,
human actions such a choosing wrong passwords and inputted passwords in not secure way are regarded as” the weakest
connection” in the authentication chain. Rather than arbitrary alphanumeric character, users tend to select a password
either short or his name related for easy memorization. With web site applications and mobile phone apps charging up,
peoples can get access these types of application anytime and anywhere with multiple devices. This evolution brings good
convenience but also improves the probability of exposing passwords to shoulder surfing attacks. Attackers can observe
directly or use external recording devices to collect users’ credentials. To come this problem, we proposed a novel
authentication system Pass Matrix, based on graphical passwords to resist shoulder surfing attacks. Many
authentications methods are presented, but users are familiar with textual password method. Textual password methods
are vulnerable to shoulder surfing and key loggers. To come this problem many other authentication system like token
based authentication, biometric bases authentication systems, graphical password methods have been proposed. However
biometric bases authentication systems are costly and graphical password systems are not that secure and efficient.
