Framework for ATM Card & Safety: Preventing ATM Transaction from Hackers and Frauds

Abstract

Authentication is possible in several ways namely text password, graphical, bio-metric, and 3 dimensional password authentication. In this paper we have tried to overcome the authentication problem involved due to pin hacking of ATM cards by introducing multi-level authentication technique. The use of ATM card is increasing and making headway day by day among the humans, moreover giving rise to malignant attacks on bank accounts via ATM cards due to limited security & authentication technique i.e., PIN used for ATM transactions. To resolve this problem, paper will focus at concept of graphical-text authentication that will be done by the bank at time of signing-up along with ATM card confidentially to the possessor / owner itself. When possessor will swipe ATM card into machine, as soon as the ATM card will get accepted, the possessor will have to choose an image from 9 images shown and that image must match the image he chose at time of registration. After choosing correct image possessor will have to go through second level of security i.e., he have to choose 4 grid points on that image in a particular sequence that he did at time of registration. If security level is passed with correct grid points then, possessor will get a random encrypted form of PIN number by clicking on chip at ATM window. This will reduce ATM attacks and frauds to a great extent.
