Enhancement of two-tier ATM security mechanism: Towards providing a real-time solution for network issues

Abstract

In the current scenario, the crime rate has tremendously increased with respect to the Automatic Teller Machine (ATM). During the last few years, criminals are becoming more sophisticated and paid more attention to ATMs. The majority of ATMs in India are working on a single authentication technique. The attacks, such as skimming, shimming, card cloning, card swapping, shoulder surfing, etc. works due to the use of minimal authentication in ATMs. So, the concern about the security of ATMs is reached to its peak level. Nowadays, banks have moved towards the two-tier authentication level. Recently in India, some banks have adopted the One Time Password (OTP) mechanism along with a UID number to perform the transaction in ATMs. In such a case, dependency on the cellular network for OTP is also a significant concern. To overcome these types of issues researcher proposed a two-tier authentication mechanism. The paper addresses the recent problems and their solution with the help of a two-way authentication method. To resolve the network issue, the researcher also proposed a novel technique, i.e., Security Question-based verification mechanism.
