Enhancement of the Security of Pass-Go Pattern Password Using Shuffling Grid-Shapes

Abstract

The trend of the graphical passwords is rising and every year a number of new password scheme are being launched by researchers from the various parts of the world.Password patterns, as used on current Android phones, and other shape-based authentication schemes are highly usable and memorable. In terms of security, they are rather weak since the shapes are easy to steal and reproduce. In this work, we introduce an implicit authentication approach that enhances password patterns with an additional security layer, transparent to the user. In short, users are not only authenticated by the shape they input, but also by the way they perform the input. The smart phones which use number based authentication scheme or a fixed point based android like pattern scheme are prone to the shoulder surfing attacks, which is a type of password guessing using social engineering as a hacking tool. We have proposed security critical authentication model for the smart phones, which is purely based on the uniqueness of the password combinations and ease of access. We have proposed and implemented a critical improvement in the existing pass-go pattern password based scheme. The improved scheme is using shuffling points and shuffling shapes based pattern password scheme is designed to mitigate the threat of the password guessing attacks (graphical) as well as encouraging developers to adopt much secure password schemes.
