Web Services are rapidity becoming the enabling technology of today's e-business and e-commerce systems, and will soon transform the Web into distributed applications. The aim of this paper is to present our approach in applying Web Services into the Internet transaction banking system. The system is integrated among backend system of banks so that each bank system can communicate with each other in order to perform transactions in transferring money from an account in one bank to an account in the partner bank and vise versa. The backend systems of banks are heterogeneous information systems; therefore it is difficult to build a common environment using existing distributed technologies. Web Services provide a means for different organizations to connect their applications with one another to conduct business across a network in a platform and language independent manner [1]. The paper will examine these benefits of Web Services and apply these features into the Internet banking transaction system regardless of platform, programming languages as well as existing backend system of banks.

The Internet banking service, through which customers process their banking-related works, was introduced in July 1997. The service has since spread quickly, and as of the end of June 2000, just one year after its introduction into Korea, its subscribers numbered 1.23 million people. This figure is ten times larger than the 120,000 subscribers recorded over the six months period up to the end of 1999. In addition, since the end of June 2000, subscriptions on average increase by more than 10,000 a day, and by the end of December 2000, it is expected to pass the 3 million mark. There has been no empirical study conducted on the invigorated Internet banking's status and its services. Therefore, this research is designed to conduct a survey on the Internet banking service status, to conduct actual transactions from the viewpoint of customers and then make a empirical evaluation of it. This will indicate directions for improvement and development of the domestic Internet banking service. We have evaluated ten areas of the Internet banking service including financial service, customers service, users'convenience, and system safety. As of the end of June 2000, 18 out of 20 commercial domestic banks are providing an Internet banking service, and we have conducted evaluations of all these banks. The evaluation is divided into ten categories with 100 points as a maximum score. These are then classified into six grades AAA, AA, A, BBB, BB and B. The outcome of this evaluation was featured in the major domestic journals, and the banks, acknowledging the value of the report, declared that they would adopt it as their criteria for evaluation.

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.

최근 모바일뱅킹 사용의 일상화와 더불어 은행권에서 모바일뱅킹의 사용 비중이 더욱 커져감에 따라 보안 위협도 증가하고 있다. 이에 국내 금융권에서는 뱅킹 어플리케이션 내에 보안 솔루션들을 도입하고, 상시 실행되는지 여부를 확인하기 위하여 보안 검사 지점들을 설정하여 어플리케이션의 안정성을 보장하고 있다. 본 논문에서는 국내 주요 은행들의 안드로이드 뱅킹 어플리케이션 디컴파일(decompile)시 추출되는 중간언어를 정적 및 동적 분석하여 보안 검사 지점들을 우회하는 모바일 백신 프로그램 미작동의 취약점을 보인다. 또한, 결과를 통해 이를 악용할 수 있는 공격을 알아보고 대응 방안을 제시한다.

Along with the trend of financial globalization, Vietnam has undergone a process of increasing financial integration. The great capital inflow poses a problem for the monetary policy's ability to follow a planned target during the changes in the global financial markets. This paper aims to examine the impact of financial integration on monetary policy independence in Vietnam and investigate the role of foreign exchange reserves on this relationship. The research borrows from Mundell-Fleming's Trilemma theory. The results show that increasing financial integration reduces the independence of monetary policy in the short term, and foreign exchange reserves have not shown an apparent role in Vietnam. In addition, increasing exchange rate stability has a negative impact on the independence of monetary policy, but it has an impact on growing market confidence and partly supporting the management process of monetary policy in the short term. Therefore, in the long run, Vietnam needs to allow exchange rate flexibility more, but there should not be sudden changes; the size of foreign exchange reserves should be strengthened to facilitate the implementation of an independent monetary policy with an obvious impact in the context of an increasing scale of international capital flows in the future.

최근 우리나라를 비롯한 EU, 영국 등은 금융구조 개혁 및 금융소비자의 편의성 제고를 위하여 금융회사가 보유하고 있는 금융정보를 핀테크기업에게 개방하는 오픈뱅킹을 적극 추진하고 있다. 향후 오픈뱅킹이 점차 활성화될수록 오픈뱅킹 제공기관의 안정성 확보 및 이용자 보호의 중요성은 더욱 커질 것이다. 특히 우리나라는 전자금융거래의 안정성과 신뢰성 확보를 위하여 2007년부터 시행해 온 전자금융거래법이 있지만, 오픈뱅킹 제공기관에게 적용하기 어려운 한계가 있어 오픈뱅킹에 대한 보안사고 예방 및 이용자 보호가 취약해질 위험성이 있다. 따라서 본 논문에서는 오픈뱅킹에 관한 외국의 규제를 살펴보고, 국내 오픈뱅킹의 안정성 강화 및 이용자 보호를 위한 규제 개선 방안을 제시해 본다.

최근 금융산업의 글로벌 트렌드인 오픈뱅킹(Open Banking)이 향후 금융시장 내 다양한 혁신을 일으키는 원동력이 되고 금융업의 분화와 재결합을 촉발하기 위해서는 올바른 정책방향과 세부 과제의 추진이 중요하다. 본 연구는 오픈뱅킹의 등장배경, 국내외 동향 그리고 한국의 오픈뱅킹 정책을 조사·분석하고, 오픈뱅킹 제도의 성공적인 안착과 활성화를 위한 정책방향과 추진과제를 제언하고자 한다. 오픈뱅킹은 고객의 명시적 동의를 전제로 제3자(TPP: Third Party Provider)에게 은행 계좌 등에 대한 접근을 허용하고 지급결제(Payment) 기능을 개방하는 정책이다. 오픈뱅킹 시대 개막은 은행과 핀테크 기업 간의 경쟁과 협력이 본격적으로 시작되는 계기가 되어 금융산업의 경쟁력을 높이고 금융소비자의 효용 증대에 기여할 것으로 기대된다. 이를 위해 정책당국은 개방형 금융결제 인프라 의 고도화, 오픈뱅킹 법적 근거 마련과 함께 고객 데이터 유출, 금융시스템 안정성 저하 등의 부작용을 최소화하는데 만전을 기해야 한다. 은행과 핀테크 기업은 흩어져 있는 고객 금융정보를 하나의 플랫폼으로 단순 집중하여 상품 또는 서비스를 추천하는 금융서비스의 표면적 결합을 넘어 진정한 금융서비스의 융합과 차별로 발전시켜야 할 것이다.

This paper examines market concentration and its effect on competition in the Chinese commercial banking market. This study also investigates how changes in competition have affected the financial stability of Chinese commercial banks. To test the competitive conditions, we obtained the H statistic of the Panzar-Rosse model from a revenue function equation. The degree of financial stability is estimated by the Z-score formula. The Chinese banking industry has become an increasingly less concentrated market with an increased number of banks. Along with a decreased market concentration, competition in the Chinese banking industry has improved moderately. However, its market structure is still far from a competitive market. An individual bank's ability to earn higher markup or charge a higher net interest margin contributes to its financial soundness, although a higher degree of market concentration may have negative effect on the financial stability of the entire banking system.

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.
