Enhanced Authentication Mechanism for Automated Teller Machine (ATM) through Implementation of Soft Two-Factor Authentication

Abstract

The demand of Automated Teller Machine (ATM) is exponentially increase from 2003 to 2018 which makes the ATM as important component in modern banking. The easiness and flexibility to have a transaction at any time without the need to stand in a long queue and dealing with administration make ATM is preferable by a lot of bank customers. However, it is also a big attraction point for criminals and fraudsters. Skimming is one of the threat of ATM service which will allow fraudster to create a clone card through duplication and combination of eavesdropping techniques such as shoulder surfing or installation of miniature video camera, utilization of counterfeit hardware proximity, etc. Therefore, an enhanced method of authentication shall be implemented to maintain the security of ATM service. In this work, we are proposing a new mechanism of ATM authentication which will enhance its security through the use of Soft Two-Factor Authenticator. The analysis of our proposed mechanism is done using NIST SP800-63B to ensure its security against possible techniques for skimming. Henceforth, it provides an additional security against skimming.
