Providing Advanced Security for Card Validation Using Enhanced Luhn Algorithm in Cloud Computing

Abstract

The most important security issue in cloud computing which is disturbing the organizations is data protection, because they will not transfer their data to remote machines if there is no guarantee about data protection from the cloud service providers. One of the sensitive issue that is related to data protection is card data (credit, master, visa etc.,) protection. The existing techniques/algorithms for card data security have undergone some failures regarding the confidentiality and integrity matters. Sometimes, the sensitive data or information generated in unencrypted format to other systems resulted in unauthorized access and disclosure. Based on these reports, in this paper we presented an IBM Cloud Hardware Security Module (HSM) encryption and tokenization-based system for credit and debit card information security. The proposed system consists of the HSM and card processing modules as well as Enhanced Luhn Module (ELM).The ELM is a luhn based card validation system, which can compute and processcard transactions in restricted and more securely in cloud. The implementation of the system was carried out on Intel core i7 9th generation processorand 8 GB of RAM on Red Hat Enterprise Linux 7.7 Operating System. TOMCAT server and HTML with CSS JavaScript served as the frontend with JDK 1.7 for business processing and MySQL as a database. Analysis of the results of implementation with Master, Amex and Visa cards showed that the system delivered very high usability and more secured experience for users.
