Recently, internet banking is growing rapidly. Moot banks in Korea provide internet banking services. Internet banking becomes a major trend in the financial marketplace. With advanced computer technology and declining communication costs, many customers prefer online alternatives such as internet banking, mobile banking or phone banking rather than going to banks by themselves. The number of customers using those alternatives is skyrocketing and domestic commercial banks encourage them of the use. As the internet is highly developed, customers demand higher quality services and banks develop and provide diverse services in order to respond to them. However, internet banking service users are still afraid of their personal and financial information being exposed on the internet. The purpose of this research is to empirically analyze the influence that appropriate internet banking affect user's security intention. The research model proposed in this study includes user's security intention which is influenced by self-efficacy, security trust, Internet banking attitude, perceived security and security intention. According to the result of this study, self-efficacy and security trust are related to the security attitude. There is a significant relationship between security attitude and perceived security. Also, user's security attitude and perceived security is significantly affected by security intention.

According to the development of information processing technology and mobile communication technology, the utilization of mobile banking systems is drastically increasing in banking system. In the foreseeable future, it is expected to increase rapidly the demands of mobile banking in bank systems with the prevalence of smart devices and technologies. However, the keeping 'security' is very important in banking systems that handles personal information and financial assets. But it is very difficult to improve the security of banking systems only with the vulnerabilities and faults analysis methods of information security. Hence, in this paper, we accomplish the analysis of security risk factor and security vulnerability that occur in mobile banking system. With analyzed results, we propose the information security control and management processes for assessing and improving security based on the mechanisms which composes mobile banking system.

Technology Acceptance Model (TAM) considers perceived ease of use and perceived usefulness as the important determinants of user behavior regarding information technology. As an extension of TAM, this research examines perceived security as an additional determining variable to explain an individual's acceptance and use of mobile banking as well as internet banking. The results show that perceived ease of use does not affect the individual's attitude toward the use of mobile or internet banking, while perceived usefulness does. Furthermore, perceived security affects perceived usefulness in mobile banking, but not in internet banking. In addition, in mobile banking, perceived security is positively related to perceived usefulness, though perceived security is negatively related to attitude. Finally, the average scores of surveyed data for Internet banking are higher and significantly different than those for mobile banking.

Due to rapid development of mobile device technologies, the mobile banking through Internet has become a major service of banking information systems as a security-critical information systems. Recently, lots of mobile banking information systems which handle personal and transaction information have been exposed to security threats in vulnerable security control and management processes, mainly software systems. Therefore, in this paper, we propose a process model for software security improvements in mobile banking information system by application of fault tree analysis(FTA) and failure modes and effects analysis(FMEA) on the most important activities such as 'user authentication' and 'access control' and 'virus detection and control' processes which security control and management of mobile banking information systems are very weak.

The fusion of Internet technology and applications with wireless communication provides a new business model and promises to extend the possibilities of commerce to what is popularly called mobile commerce, or m-commerce. In mobile Internet banking service through wireless local area network, security is a most important factor to consider. We describe the development of security service for mobile Internet banking on Personal Digital Assistants (PDAs). Banking Server and Authentication Server were developed to simulate banking business and to support certificate management of authorized clients, respectively. To increase security, we took hybrid approach in implementation: symmetric block encryption and public-key encryption. Hash function and random number generation were exploited to generate a secret key. The data regarding banking service were encrypted with symmetric block encryption, RC4, and the random number sequence was done with public-key encryption. PDAs communicate through IEEE 802.IIb wireless LAN (Local Area Network) to access banking service. Several banking services and graphic user interfaces, which emulatedthe services of real bank, were developed to verity the working of each security service in PDA, the Banking Server, and the Authentication Server.

We expect that the accredited certificate-based open banking, which is actively deployed in recent times, will solve the Galapagosization problem of the existing accredited certificate-based closed banking by supporting standard communication protocol and web compatibility. However, it is questionable how much the open banking will answer the security and usability problems of the existing closed banking. This paper is focused on analyzing the differences between the existing closed banking and the open banking, and then evaluates how much the security and usability problems of the existing closed banking are resolved by the open banking. The study firstly analyzes the security vulnerabilities raised in the process of providing closed banking services for the past 15 years or more, the countermeasures applied to enhance security, and the convenience impact of countermeasures. And then, the security and convenience of the open banking is inferred by analyzing the implementation difference between the closed banking and the open banking. The paper also briefly discusses how to improve the open banking to resolve the remaining problems of the open banking.

The objective of the present study is to identify the security factors that influence customer trust towards intention to continue using Internet banking in Malaysia. The participants are individual Internet banking users in Peninsular Malaysia. Data was collected through self-administered questionnaires distributed using the drop-off and pick-up (DOPU) technique to bank branch managers who then passed the questionnaires to their customers. A total of 413 respondents completed the questionnaires. The SPSS statistical analysis software package and Partial Least Squares statistical method were used for data analysis and hypothesis testing. The results show that authentication, confidentiality, data integrity and non-repudiation are significant factors that influence customer trust towards intention to continue using Internet banking. Trust plays a critical role in influencing the intention to continue using Internet banking in Malaysia while perceived privacy does not. An understanding of the factors identified in this study will enable Internet banking providers to effectively and efficiently enhance the security of services and thereby promote continued usage of Internet banking among customers. The findings of this study are thus expected to be of great use to Internet banking providers as improvements in Internet banking security will increase business in the long run.

As smart phones have become widely adopted, they have brought about changes in individual lifestyles, as well as significant changes in the industry. As the mobile technology of smart phones has become associated with all areas of industry, it is not only accelerating innovation in other industries such as shopping, healthcare service, education, and finance, but is also creating new markets and business opportunities. The preparation of thorough security measures for smart phones is increasing in demand. While offering excellent mobility and convenience, smart phones can be exposed to a range of violation threats. In particular, it is necessary to make efforts to develop a security system that can preemptively cope with potential security threats in the banking service area, which requires a high level of reliability. This paper suggests a security reference model that is considered for the smart phone-based joint mobile banking development project being undertaken by the Bank of Korea in 2010. The purpose of this study is to make a security reference model for a reliable smart phone-based mobile financial service, by recognizing the specific security threats directed toward smart phones, and providing countermeasures to these security threats. The proposed mobile banking security reference model is useful in improving system security by systematically analyzing information security threats to the mobile financial service, and by presenting the guideline for the preparation of countermeasures.
