Advanced pin entry method by resisting shoulder surfing attacks

Abstract

The individual distinguishing proof number or (PIN) and Passwords are the remarkable well known verification strategy used in different gadgets, for example, Atms, cell phones, and electronic gateway locks. Unfortunately, the traditional PIN-entrance technique is helpless vulnerable against shoulder-surfing attacks. However, the security examinations used to support these proposed system are not focused around only quantitative investigation, but instead on the results of experiments and testing performed on proposed system. We propose a new theoretical and experimental technique for quantitative security investigation of PIN-entry method. In this paper we first introduce new security idea know as Grid Based Authentication System and rules for secure PIN-entry method by examining the current routines under the new structure. Thus by consider the existing systems guidelines; we try to develop a new PIN-entry method that definitely avoids human shoulder-surfing attacks by significantly increasing the amount of calculations complexity that required for an attacker to penetrate through the secure system.
