As the increase of transaction using mobile banking continues, threat to the mobile financial security is also increasing. Mobile banking service performs the financial transaction using the dedicate application which is made by financial corporation. It provides the same services as the internet banking service. Personal information such as credit card number, which is stored in the mobile banking application can be used to the additional attack caused by a malicious attack or the loss of the mobile devices. Therefore, in this paper, to cope with the mobile financial accident caused by personal information exposure, we suggest outlier detection method which can judge whether the transaction is conducted by the appropriate user or not. This detection method utilizes the user's input patterns and transaction patterns when a user uses the banking service on the mobile devices. User's input and transaction pattern data involves the information which can be used to discern a certain user. Thus, if these data are utilized appropriately, they can be the information to distinguish abnormal transaction from the transaction done by the appropriate user. In this paper, we collect the data of user's input patterns on a smart phone for the experiment. And we use the experiment data which domestic financial corporation uses to detect outlier as the data of transaction pattern. We verify that our proposal can detect the abnormal transaction efficiently, as a result of detection experiment based on the collected input and transaction pattern data.

Purpose First, this study examines the relationship between characteristics of smartphone banking and trust of smartphone banking. Second, this study investigates the impact of perceived benefit on the trust and usage intention of smartphone banking. Finally, this study considers moderating effect of service quality in the relationships between perceived benefit and trust and usage intention of smartphone-based mobile banking. Design/methodology/approach This research uses the survey method to test its hypotheses, the survey population is smartphone baking users. A software tool called AMOS 17.0 used to analyze the research model. Findings The results showed that characteristics of smartphone banking channel like compatibility, timeliness, and mobility had a positive effect on the trust of smartphone banking. The device familiarity showed a significant positive impact on trust of smartphone banking. While the service quality moderated the relationship between trust and usage intention of smartphone banking, moderating effect of service quality in the relationship between perceived benefit and its usage intention was not significant. The results of this study could provide a theoretical framework to explain customers' decision of smartphone banking and practical implications for banking venders.

In this paper, we propose 3-factor mobile banking authentication scheme applied to face recognition techniques with existing certificate and OTP. An image of the user's face is captured by smart phone camera and its brightness processing of the contour of a face and background by n of X and Y points. Then, distance between the point of eyes, nose and mouth from captured user's face are compared with stored facial features. When the compared results corresponding to the data that stored in a face recognition DB, the user is authenticated.

The purpose of this study is to find out the factors of customer satisfaction as the critical success factors of mobile banking. Based on previous exploratory work and a review of the literature of customer satisfaction, nine key factors are identified: perceived usefulness, perceived easy of use, perceived ubiquity, perceived safety, perceived tangibles, perceived reliability, perceived responsiveness, perceived assurance, and perceived empathy. A conceptual model is developed and hypotheses are empirically examined using multiple regression analysis. The result of this research are summarized as follows: First, perceived usefulness, perceived easy of use, perceived safety, and perceived empathy have significant influence on customer satisfaction. Second, customer satisfaction has significant influence on reuse intention and word-of-mouth intention.

Securing user authentication and transaction continuation is very critical in mobile banking. Malicious software, which is installed in user's smart phone, can either steal user's password or induce user to confirm manipulated transaction by handling transaction resource. In this paper, we propose schemes, that are aimed to secure user's password or to secure transaction confirmation, based on the security and usability analysis of existing schemes.

Based on prior studies functional benefits, social benefits, experiential benefits, and personalization are identified as affecting factors of the user's attitude and usage of smart banking application. According to the results of multiple regression analysis, all benefit factors(functional benefit, experimental benefit, social benefit) and personalization were found to be significantly related to the user's attitude. Users' attitude on smart banking was found to be significantly related to the real usage as well. This paper has value in that it investigates the attitude and usage of smart banking in terms of benefits.

The purpose of this study is to try to IPA(Importance-Performance Analysis) by applying text mining approaches to user review data for korea mobile banking applications, and to derive priorities for improvement. User review data on mobile banking applications of korea commercial banks (Kookmin Bank, Shinhan Bank, Woori Bank, Hana Bank), local banks (Gyeongnam Bank, Busan Bank), and Internet banks (Kakao Bank, K-Bank, Toss) that gained from Google playstore were used. And LDA topic modeling, frequency analysis, and sentiment analysis were used to derive key attributes and measure the importance and satisfaction of each attribute. Result, although 'Authorizing service', 'Improvement of Function', 'Login', 'Speed/Connectivity', 'System/Update' and 'Banking Service' are relatively important attributes when users use mobile banking applications, their satisfaction is not at the average level, indicating that improvement is urgent.

Technological developments facilitate payment transactions. In 2020, Bank Indonesia issued a regulation that supports QR payments using the Indonesian Standard Quick Response Code (QRIS). PT ABC is one of the banks that launched a QR payment feature on mobile banking with QRIS standards to make it easier for customers to make payment transactions at various merchants. In its implementation, the interest of QR payment users still tends to be small, so an analysis of the interests of QR payment users is carried out. The purpose of this study is to analyze the factors that influence user interest by using a modified UTAUT model. The UTAUT model was modified by adding variables to perceived trust, perceived risk, perceived regulatory support, and promotional benefits. The population taken is the company's customers in the DKI Jakarta area and it takes 403 samples for this case study. The results of empirical analysis show that 8 out of 12 hypotheses are considered proven where business expectations, social influence, perceived trust, perceived risk, perceptions of regulatory support, promotion benefits, age-moderated performance expectations, and age-moderate effort expectations have a significant effect on behavioral intentions, while performance expectations, facilitation conditions, business expectations are moderated by experience and social influence.
