State of the Art: Secure Mobile Payment

Abstract

With mobile payments popular around the world, payers can conduct a payment anytime and anywhere. While providing great convenience, mobile payment also brings many payment security issues. This paper is the first comprehensive review of secure mobile payment. We classify the mobile payment into TPC(third-party payment company)-led mobile payment and Bank-led mobile payment, and based on this, summarize the system structure of mobile payment. Then we discuss the mobile payment security technology framework from Tokenization, PAN(bank card primary account number) binding, and Secure Payment Authentication, respectively. Besides, this paper introduces secure technologies(hardware and software) used in these procedures, discusses and analyzes the security issues that they have been encountered, summarise open issues, and proposes future development directions. In the end, we give the discussion and comparison of popular and representative mobile payment applications, including Alipay, Wechat Pay, Apple Pay, Samsung Pay, and Google Pay. INDEX TERMS Tokenization, symmetric cryptosystem, hybrid cryptosystem, PAN binding, TOTP, remote payment, near-field payment.

Therefore, the researchers of this study believe that the inability to provide a good instant interactive experience belonging to their own brand is a relevant reason why the parent enterprise of Ant Forest cannot strengthen the consumer-brand engagement of Ant Forest users through interaction.…”

AI Based Mobile Bill Payment System using Biometric Fingerprint

It is a time-efficient method to complete a transaction as the user has to scan the QR code (Liu et al, 2020) with their smartphone. The users always need to have money preloaded in these applications these require a constant internet connection as all the transactions are online.…”

E-Money Security Dilemma: Advanced Cybersecurity Mechanisms and Legacy Mobile Payments in Sub-Saharan Africa

“…During financial transactions, tokenization is used to substitute the actual mobile money account number with non-sensitive placeholders. Tokenization is especially practiced in the payments processing industry and the process involves protecting sensitive data by replacing them with an algorithmically generated number called a token that is by design unrelated to the actual data (Liu et al, 2020;Iwasokun et al, 2018).…”
