ATM Security Framework for Ethiopian Banks

Abstract

Automated teller machine (ATM) security is the current issue throughout the world. ATM users increase every time because it is more convenient to use rather than to go to a branch. So, many banks, including Commercial Bank of Ethiopia, are trying to install ATM machines throughout the country to facilitate financial transactions. ATM machines are located in different areas which are suitable to customers to get the service anytime and anywhere. But this may cause various security problems. ATM threat can be divided in to three major categories. Those are logical threat, physical threat and fraud commonly known as skimming. On this study we tried to investigate these threats in the local context. Based on which we proposed an improved ATM security framework. Our preliminary survey indicated that banks do not use procedures to secure their ATM machines. The main objective of this study is, therefore, to design an improved framework that is used to secure ATM machines and, any bank can use this framework to enhance its ATM security. To validate the framework MATLAB with specific scenarios that model common ATM tasks has been executed. The result show that on the MATLAB simulation on biometric (voice and finger print) measure uniquely identify high level of security which is by far stable and secure ATM system that of the current authentication system on practice.
