Since the internet banking service was introduced to Korea in 1999, the service has placed itself as an indispensable service to most users. The internet banking, which provides convenience for internet users as well as efficiency for banks, is expected to increase its importance more and to play a bigger role as a passage of funds. Meanwhile, numerous accounts as to the misusage of the internet banking service have been reported and the types and size of damages, especially making illegal money transfers and embezzling user information through computer hacking, tend to increase continuously. This paper points out fundamental problems of the current internet banking service by analyzing the all components of the internet banking service and fitting the results of structural analysis of hacking threats in accordance with service flow. This paper also attempts to propose the means to minimize the hacking threats of the internet banking service.

본 연구에서는 응답자들의 라이프스타일을 먼저 몇 개의 요인으로 분석 한 후, 도출된 요인들을 다시 군집분류를 하였다. 추출된 군집들에 따라 인터넷 뱅킹 신뢰성과 인지도 그리고 소득수준이 인터넷 뱅킹 이용도에 어떤 차이를 보이는지 분석하였고, 전체 군집에서 나온 결과와 어떤 차이를 보이는지 비교 분석 해보았다. 그 결과 라이프스타일에 따라 4개의 군집이 분류되었으며, 군집1을 '적극적 활동형', 군집 2를 '현실적 가족형', 군집 3을 '전통적 보수형', 군집 4를 '소극적 비활동형'으로 명명하였다. 군집들에 따라 신뢰성, 인지도, 소득수준이 인터넷 뱅킹 이용에 영향을 미치는지에 대한 연구 결과로는 전체군집에서는 소득에만 영향을 받았으나 군집을 세분화하여 세분화된 군집별로 알아본 결과 전체 군집과는 달리 '적극적 활동형'은 신뢰성, '전통적 보수형'과 '소극적 비활동형'은 소득수준, 그리고 현실적 가족형은 아무 영향을 받지 않는 것으로 보아 시장을 세분화 하였을 경우와 세분화 하지 않았을 경우의 연구 결과는 다르다는 결론을 얻어냈으며, 인터넷 뱅킹 활성화에 있어서도 라이프스타일에 따른 고객 세분화는 큰 의미가 있다.

The purpose of this study is empirically analyzing the effects of external factors(user knowledge, service characteristics, security), perceived risk, trust, ease of use, and usefulness on continuous customer acceptance in Internet banking. To achieve the goal, we develop the extended Technology Acceptance Model(Ex-TAM) based in the theoretical backgrounds of the Technology Acceptance Model(TAM). To test the new model(Ex-TAM), path analysis is performed by AMOS 4.0 package as a statistical tool. The finding indicate that 4 factors(service characteristics, ease of use, usefulness, trust) are significant. However, 2 factors(security, perceived risk) are not significant, user knowledge is partly significant.

This study investigates time series data on internet banking systems and business performances for 5 large-scale banks : Kookmin, Woori, Hana, City, Shinhan. These banks have the common features that they merged with other banks around 2000, hence they experienced massive IS integration between banks. This study adopted VAR and VECM for identifying Granger causality between the quality of internet banking systems and the performances of banks(operating revenue and cost). The main results are as follows. First, internet banking system impacts positively on the revenues as well as costs of banks. Second, the improvement of internet banking system is instigated by cost part more than revenue part. Hence, the results imply that banks tries to reduce operating costs via internet banking systems, however the systems rather increased the costs of banks, although the systems increased operating revenues of banks too.

The importance of Internet banking has been emphasized due to the spread of Internet and the potential advantages of Internet banking. In case of Korea, Internet banking users have been risen dramatically since 1999 after its introduction. The purpose of this study is to draw the antecedent variables that affect the adoption of Internet banking and show their effects empirically. In this paper, influencing factors are proposed to distinguishing Internet banking users from non-users. And nine hypotheses are empirically tested using logistic regression. The results show that most of hypotheses are supported except for complexity and IT innovativeness. And compatibility was found to have a strong positive effect on the adoption of Internet banking. Implications of these findings are discussed for researchers and practitioners.

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.

As Internet banking service became popular, many users can exchange goods by online. Even though this advantage, there are incident cases in the Internet banking service due to security threats. In order to counteract this problem, various security techniques have been applied over whole area in the Internet banking service. Therefore, we described that analyzed results of security techniques applied in the financial institutions area and network communication area in this paper. We consider that this paper will be useful as a reference to protect security threats occurred by insiders and vulnerabilities in implementation.

The paper tests the hypothesis that Internet banking reduces cost and ultimately enhances profitability for banks. Our analysis suggests that Internet banking does contribute to cost reduction but does not affect profitability. The implications are that the primary objective of Internet banking has been accomplished, but has not reached the stage in which the benefits overcome the burden of initial investment. The findings also offer the implication that Internet banking probably raises social welfare by passing on the benefit of cost reduction to customers rather than resulting in enhanced profits. In addition, we find that the banking customer's preference for face-to-face transactions may be very low in Korea, which supports the hypothesis that the cost in securing a customer base will be reduced significantly.

Seventeen domestic banks, Hongkong & Shanghai Banking Corporation Ltd. and Korea Post provide their subscribers with banking services such as statement service, funds transfer, and application for loans through Internet banking sites, which have become ever-increasing banking services for individual and corporation and government subscribers. First, this study aimed at presenting a process of determining factors to measure customers' perception while using Internet banking for doing transactions. Secondly, this paper attempted to unveil a list of major factors that Internet banking customers perceive while accessing the web sites to do their business with their banks. This study also suggested the features of those factors, which would help improve our understanding of Web usage for Internet banking. This result of the paper will lead further understanding of factors associated with Internet uses in other economic activities, which enable practitioners such as web designers and security specialists to provide Internet banking subscribers with better services in a safe and convenient web pages.

은행이 급변하는 마케팅환경에 적극적으로 대처하고 인터넷뱅킹 시대를 맞이하여 경쟁의 우위를 점하기 위해서는 안정적인 인터넷뱅킹 서비스의 공급이 필수적이다. 이를 위 해서 은행은 기존의 물리적인 고객 접점에서 인터넷의 전자적인 공간을 이용한 가상은행의 구현이 필연적이며 이러한 목표를 달성하기 위해서는 금융전산망의 완벽한 보안이 선결되어 야 한다. 이러한 관점에서 국내 은행들이 전자상거래에서 가상은행을 통한 전자지불시스템 의 구축시 선행되어야 할 전산망 보안에 관한 연구를 국내 금융기관의 실정에 맞게 모델을 선정하고 발전된 모델을 제시하였다.
