A Survey on Shoulder Surfing Resistant Text Based Graphical Password Schemes

Mokal P. H., Devikar R. N.

Abstract: For security authentication is important factor in any computer system. Authentication is the process of determining whether someone or something is in fact, who or what it is declared to be. In computer system authentication is done through use of password. The alphanumerical username and password is well known and commonly used authentication approach. As this approach is easiest one and provides security to some extent but it has some significant drawbacks such as if user selects short password which is easier to remember then it can be easily guessed or hacked by hackers and on the other side if user selects too long and difficult password then it is difficult for user to remember it for long time. To overcome the drawbacks of traditional authentication approach researcher have been developed new authentication approach as possible alternative to alphanumeric or text based approach. This new proposed approach uses images, pictures as a password known as Graphical password approach. The researcher have been designed Graphical passwords in such a way that passwords are easier for people to use, to create and so that more usable and secure. As graphical password provides security to certain degree but it is vulnerable to shoulder surfing attack. When user enters their password in public place then it can be capture by attacker by direct observation or by recording the users authentication session. This attach is known as Shoulder surfing attack. In this paper we will conduct comprehensive survey of existing shoulder surfing attacks in text based graphical password approach by studying five papers on shoulder surfing resistant graphical passwords and explains the problems and their possible solutions.
