Among the various services for mobile banking, user authentication method using bank security card is still very useful. We can use mobile banking easily and safely in case of saving encoded security codes in smart phone and entering codes automatically whenever user authentication is required without bank security card. In this paper automatic recognition algorithm of security codes of bank security card is proposed in oder to enroll the encoded security codes into smart phone using smart phone camera. Advanced adaptive binarization is used for extracting digit segments from various background image pattern and adaptive 2-dimensional layout analysis method is developed for segmentation and recognition of damaged or touched digits. Experimental results of proposed algorithm using Android and iPhone, show excellent security code recognition results.

'05. June, the first Internet banking accident occurred by the malignant cord. It discontinued security programs for protecting important financial informations. A computer hacker had made a collation of password, OTP(One Time Password) values etc and illegally withdraw one´s savings from the bank using the financial information. The attackers are continuously attempted with the hacking tool under bypass security programs as the vaccine program or the personal fire-wall. Therefore, an electronic financial system should be composed with the goal which is to protect financial informations from user's terminal to a banking server. In this paper, we make an analysis of menaces in electronic financial transactions and explain considerable security issues to enhance safety in Internet banking, CD/ATM and mobile banking.

The Internet banking service provides convenience than the traditional offline services. However, it still causes a number of security problems including hacking. In order to strengthen security, the financial institutions have provided such authentication methods as the official authentication certificate, the security token, the security card and OTP. However, the incidents related to hacking have continuously occurred. Especially, various weak points have been suggested for the authentication methods in regard to such types of hacking as the memory hacking or the MITM attack. So I needed was a new authentication method. In this study, the two-channel authentication method which provide two-way authentication on the user's PC and mobile device when executing the electronic financial transactions in the Internet banking environment is suggested. Also, by analyzing it in comparison with other existing methods, it is possible to check that the prospects of safety and credibility are strengthened.

Due to the development of the Internet, Internet banking that we are liberated from time and space has evolved into banking system. So modern life became comfortable. However, Dysfunction (malicious Information leakage and hacking etc.) of the Internet development has become a serious social problem. According to this, The need for security is rapidly growing. In this paper, we proposed the Internet Banking Authentication System using a dual-channel in OTP(One Time Password) authentication. This technology is that A user transfer transaction information to Bank through one Internet channel then bank transfer transaction information to user using the registered mobile phone or smart phone. If user confirm transaction information then bank request user's OTP value. User create OTP value and transfer to bank and bank authenticate them throgth the ARS. If authentication is pass then transaction permitted. Security assessment that the proposed system, the security requirement that the confidentiality and integrity, authentication, repudiation of all of the features provide a key length is longer than the current Internet banking systems, such as using encryption, the security provided by the Financial Supervisory Service Level 1 rating can be applied to more than confirmed.

With the rapid development of mobile technology the use of smartphone is spreading. In order to activate mobile banking and market in the future, the most important key is a secure financial transactoin. However, because many apps are developed without security check in proportional to the spread of smartphone, security threat is inevitably high. Current smartphone banking is processed as the way of the existing public certificate or OTP technique in the mobile environment, but many security hole about current technology is pointed out steadily. Therefore, in this paper we are to improve a existing security hole by reinforcing the security through multi-factor authentication and providing a physical non-repudiation.

Smart Phone devices offer convenience for users, but present a new set of security issues due to loss or malicious code. In this paper, a mobile cloud system environment is used with existing smart phones in an attempt to solve the problems in a banking environment. In order to prevent financial damages due to loss or personal information leakage by malicious code, a mobile cloud computing service that provides control and protection of personal information in environment that ensures individual authentication is used. Existing ID / Password with certificate, with the way smart phone dual password authentication scheme using the gyro sensors proposed.

The objective of this study is to get an implication through the application of Technology Acceptance Model (TAM) focused on Mobile Banking Service based on IC Chip. Thus firstly, this study reviewed the related literatures and materials. After this, this parer analyzed this TAM model with covariance structural method to search the factors influencing technology acceptance of Mobile banking service. In conclusion, the proposed model showed that 'innovation factor' influenced 'perceived usefulness' and 'user's acquaintance' influenced 'perceived ease of use'. And this 'perceived usefulness' influenced 'perceived ease of use' and this 'perceived ease of use' influence 'attitude toward use'.

Recently, Fintech, a technology that was created as a result of mixture of finance and IT technology, has become a big issue with the development of IT technology and widespread of smartphone usage. Although a continuous research to let new mobile banking payment system to settle in the domestic market is necessary, the research available is inadequate in the status quo. Trust, which is lacking at the moment, is regarded the most important factor in mobile banking payment system. This study, therefore, investigate into factors that building trust that effects people's usage of mobile financial payment systems.

Maturity measurement of privacy, vulnerability diagnosis and risk analysis methodologies is used in practical field for present a comprehensive conclusion. The common cyber services are internet banking, mobile banking, telephone banking and the like. Transaction structure, a kind of cyber-banking system, information security maturity of the existing measurement methodologies for research purposes, vulnerability diagnosis and risk analysis methodologies to be used in practical field present a comprehensive conclusion. To ensure safety and convenience for the user, convenient to deal with cyber environment is the key to the activation of cyber trading. Particularly by measuring the maturity of cyber banking system to ensure the safety of the practice field much effects are expected as a result.

This study analyzes the characteristics of customer's preferences on banking channels (branches, automated machines, telebanking, internet banking, and mobile banking) and examines the factors influencing channel usage. To accomplish this, ANOVA and multiple regression analysis are performed using customer data from Bank A. The analysis reveals that customers primarily utilizing branch counter transactions have a significant impact on the profitability of 1st and 2nd grade banks, particularly among the age group of 50 years and above. Additionally, it is observed that as customers' loan, deposit, and financial product holdings increase, branch counter transactions also increase. On the other hand, it is found that as the usage of mobile banking decreases in terms of loans and deposits, transaction volume increases.
