The Combining Method of Fingerprint and QR Code as Mutual Authentication for Mobile Payment

Abstract

The existing payment system using a debit/ credit card is not safe. The cards are easy to lose, and sometimes people forget to bring card while doing a transaction. Nowadays, payment system has shifted to the digital world. Most people never leave their mobile phones. This situation shows that there is significant opportunity to use mobile devices as mobile commerce applications, especially for paying through the use of credit cards. Unfortunately, the mobile device is still not secure and enable the variety of security risks. In this paper, we propose the protecting method of Fingerprint and QR Code as mutual authentication for the mobile payment system. QR Code and Fingerprint are combined to make mobile payment system more secure than ever. Because each of our fingers has their unique pattern, we can bring an additional layer of protection for authentication by making a sequence of which finger should be read first, second, and so on. The adoption of QR Code ensures the legibility, integrity, and confidentiality of the transmitted information, and lays a good foundation for the overall security of the system. © 2017 SERSC.
