Empirical Test of Determinants of Accepting Mobile Payment

From a global perspective, the development of 3G services in China is quite different from other countries. The factors that influence users' adoption of mobile payment are worth exploring. This study employs the Technology Acceptance Model (TAM) to examine determinant factors affecting consumers'acceptance intentions of mobile payment. We adopt Hofstede's cultural dimensions as moderators to extend the TAM model for exploring the impact of uncertainty avoidance on mobile payment acceptance. Based on the data from China and United State, we conduct a confirmatory factor analysis and the results show an adequate level of reliability and validity, with Cronbach's Alpha value, Composite Reliability (CR) value and Average Variance Extracted (AVE) value greater than 0.850, 0.823 and 0. 519 separately. The model and the relationship between the variables are confirmed based on SEM. Multi-Group Analysis is used to test the moderating effect and it shows that the moderating effects of Uncertainty Avoidance on PR-->BI, PU-->BI and SN-->BI are significant at 0.049, 0.032 and 0.000 significance level. Results support that Uncertainty Avoidance has a profound moderating effect on users' behavior intention to use mobile payment.

An Anonymous Payment Protocol withMobile Agents in Hostile Environments

By using Pedersen's verifiable secret sharing scheme and the theory of crossvalidation, we propose an a-nonymous payment protocol which have following features: protecting theconfidentiality of sensitive payment information from spying by malicioushosts; using a trustedthird party in a minimal way; verifying the validity of the share by the merchant; allowing agent toverify that the product which it is a-bout to receive is the one it is paying for; keeping thecustomer anonymous.

A Structural Topic Model for Exploring User Satisfaction with Mobile Payments

This study explored user satisfaction with mobile payments by applying a novel structural topic model.Specifically,we collected 17,927 online reviews of a specific mobile payment(i.e.,PayPal).Then,we employed a structural topic model to investigate the relationship between the attributes extracted from online reviews and user satisfaction with mobile payment.Consequently,we discovered that“lack of reliability”and“poor customer service”tend to appear in negative reviews.Whereas,the terms“convenience,”“user-friendly interface,”“simple process,”and“secure system”tend to appear in positive reviews.On the basis of information system success theory,we categorized the topics“convenience,”“user-friendly interface,”and“simple process,”as system quality.In addition,“poor customer service”was categorized as service quality.Furthermore,based on the previous studies of trust and security,“lack of reliability”and“secure system”were categorized as trust and security,respectively.These outcomes indicate that users are satisfied when they perceive that system quality and security of specific mobile payments are great.On the contrary,users are dissatisfied when they feel that service quality and reliability of specific mobile payments is lacking.Overall,our research implies that a novel structural topic model is an effective method to explore mobile payment user experience.

Touch-and-Go Mobile Payment System

Contactless mobile payment devices are fast, convenient and user friendly means for executing small value business transactions. This kind of transactions is preferred to be executed conveniently and on the fly by just tapping a mobile payment device to a mobile terminal. Mobility, convenience and fast transaction execution are very important payment system properties in potentially crowded places such as in public transportation. These properties are in practice causing transaction execution problems, such as: delays in offline transaction execution, transaction atomicity failures caused by mobile data communication drops, lack of central control on mobile transaction system components and increased vulnerability risk caused by easy physical access to the mobile transaction system components. This paper describes a holistic transaction processing model for resolving mentioned problems in micropayment mobile touch-and-go transaction systems. Defined processing model was implemented on real public transportation mobile payment system where it was proven as a robust solution for execution of small value touch-and-go mobile ticketing transactions.

Financial literacy,behavioral traits,and ePayment adoption and usage in Japan

This study investigates how financial literacy and behavioral traits affect the adoption of electronic payment(ePayment)services in Japan.We construct a financial literacy index using a representative sample of 25,000 individuals from the Bank of Japan’s 2019 Financial Literacy Survey.We then analyze the relationship between this index and the extensive and intensive usage of two types of payment services:electronic money(e-money)and mobile payment apps.Using an instrumental variable approach,we find that higher financial literacy is positively associated with a higher likelihood of adopting ePayment services.The empirical results suggest that individuals with higher financial literacy use payment services more frequently.We also find that risk-averse people are less likely to adopt and use ePayment services,whereas people with herd behavior tend to adopt and use ePayment services more.Our empirical results also suggest that the effects of financial literacy on the adoption and use of ePayment differ among people with different behavioral traits.

Towards the Advancement of Cashless Transaction: A Security Analysis of Electronic Payment Systems

In recent decades, day-to-day lifestyle requires online payments as easy and simple solutions to several financial transactions, which makes the concept of Electronic payment Systems very popular in the growth of a cashless society. In fact, cashless transactions through simple mobile apps are not merely a concept anymore rather are implemented robustly and being used extensively. On the dark side, obvious financial benefits are making these apps vulnerable to being attacked, which can be successful through security breaches. These cybersecurity issues need to be traced out and resolved to make the financial transactions through an app secure and trustworthy. In this paper, several related papers are analyzed to trace out possible cybersecurity issues in the domain of Electronic Transaction System. The objective is to establish sufficient theoretical background to propose methodologies for measuring security issues and also identify the security strength of any FinTech application and provide standard security metrics.

Secure Authentication Protocol for Mobile Payment

With the increasing popularity of fintech, i.e., financial technology, the e-commerce market has grown rapidly in the past decade, such that mobile devices enjoy unprecedented popularity and are playing an ever ncreasing role in e-commerce. This is especially true of mobile payments, which are attracting increasing attention However, the occurrence of many traditional financial mishaps has exposed the challenges inherent in online authentication technology that is based on traditional modes of realizing the healthy and stable development of mobile payment. In addition, this technology ensures user account security and privacy. In this paper, we propose a Secure Mutual Authentication Protocol （SMAP） based on the Universal 2nd Factor （U2F） protocol for mobile payment. To guarantee reliable service, we use an asymmetric cryptosystem for achieving mutual authentication between the server and client, which can resist fake servers and forged terminals. Compared to the modes currently used, the proposed protocol strengthens the security of user account information as well as individual privacy throughout the mobile-payment transaction process. Practical application has proven the security and convenience of the proposed protoco

A Trusted Mobile Payment Environment Based on Trusted Computing and Virtualization Technology

In this paper, we propose a trusted mobile payment environment （TMPE） based on trusted computing and virtualization technology. There are a normal operating system （OS） and a trusted OS （TOS） in TMPE. We store the image of TOS in a memory card to hinder tampering. The integrity of TOS is protected by means of a trusted platform module （TPM）. TOS can only be updated through a trusted third party. In addition, virtualization technology is applied to isolate TOS from normal OS. Users complete ordinary affairs in normal OS and security-sensitive affairs in TOS. TMPE can offer users a highly protected environment for mobile payment. Moreover, TMPE has good compatibility in different hardware architectures of mobile platforms. As the evaluation shows, TMPE satisfies the requirement of mobile payment well.

Analysis and Improvement on a Mobile Payment Protocol with Outsourced Verification in Cloud Service

Mobile wallet is a very convenient means of mobile payment to allow the clients to conduct the payment via their mobile devices. To reduce the computation burden of resources-constraint mobile devices, a few mobile wallet protocols with outsourced verification in cloud computing were proposed. But in some of the protocols, there exist the risk of a colluding attack of the customer and the untrusted cloud server. In this paper, we propose an improved protocol, in which the payment information is protected by Hash function and random number. The malicious customer and cloud server cannot change the payment information to conduct a collusion forgery attack to defraud the merchant. The security analysis indicates that the proposed improved protocol can enhance the security in terms of correctness, unforgeability and traceability without increasing the computational burden.
