Smart Android Graphical Password Strategy: A Review

Abstract

In recent years, when users across the world have embraced smart devices in greater numbers owing to recent advances and appealing applications, they have also become a target for criminals who are zealously attempting to breach protection. As a result, a significant number of attacks have been observed on these systems. As a result, several password-based authentication mechanisms have been proposed to counteract these attacks. Among them, the graphical password scheme is more consistent with smart devices, which are highly graphic-oriented. However, current graphical password schemes are vulnerable to a variety of assaults, including shoulder surfing, smudging, intersection attacks, and reflection attacks. Thus, the paper aims to review recent published papers on android smart phone graphical password and identify used techniques. Moreover, the paper analyzes results to give better understanding for users of such devices to protect their devices from unauthorized access and attacks.
