In this paper, we find out about the effort and status of GwangJu metropolitan city to reinvigorate traditional market. And we propose the micro payment model based on Android NFC and tokenization technique to support the small trader's micro payment in aspect of information technology more than the physical infrastructure and environmental improvement projects to reinvigorate the traditional market. The micropayment model supports facilities of payment using smart phone based on NFC, and the encryption and tokenization support the indirection authentication and privacy of users.

In this paper, we propose about NFC-based mobile Easy Payment System. Already announced about kind of similar payment system by use smart phone NFC function. However this proposition system will uses an encrypted token and user indirect authentication. This feature makes through to simplify payment without other input necessary information. Also my proposition system has easy security certification process. This mean my system does not adequately to use payment of a large amount. But in retail payment will be very useful payment system.

Design an efficient and secure electronic payment system is important for M-Commerce. In this paper, we propose an efficient Micro-Payment Protocol that allows multiple transactions using ID-based public key cryptosystem. Current PayWord system requires to generate certificate of the vendor for each transaction. In this paper, we use a session key instead of certificate key generated by Weil Pairing which use an Elliptic Curve Cryptosystem over finite field $F_q$ for transactions Therefore, it is more secure in Known key attacks as well as Man-in-the-middle attacks.

This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

Recently, payment method is one of the most hot issues for transaction of contents in mobile and internet markets. Many kinds of mobile contents services are rapidly growing with the combination of internet application services. Payment method algorithms are demanded for the stable transaction between producer and consumer. Security protocol algorithms are widely adapted for mobile Platform terminals. In this Paper, we described security mechanism for the current wireless internet services and compared with the performance result. There are security protocols that based on java machine platform or WAP protocols. The system is based on J2ME technology for the java mobile platform. Based on this technology, a security system is proposed for the service of mobile commerce electronic payment. The system is designed for the stability of transaction so that it enables to apply into many kinds of internet payment system.

Together with the activation of wireless Internet, the interest for various integrated methods of the existing wired and wireless e-commerces is on the rise. For the integrated wired and wireless e-commerce, firstly, the optimized security and authentication under the radio communication environment should be decided. And also the user-friendly usage is important. In this paper, we designed and implemented wired and wireless interworking Mobile Wallet on terminal that can be used through both wired and wireless methods by developing electronic wallet module for electronic payment using MIDP (Mobile Information Device Profile) based on J2ME (Java 2 Micro Edition). The characteristics of mobile wallet implemented in this paper provide the stability through encoding/decoding payment information and on-line usage on wired/wireless environments through downloading electronic wallet. In addition, we also present safe and convenient payment method for e-commerce based on wired/wireless Internet.

Mobile payment service is a new innovating technology in the micro payment industry. Although it emerged only one or two years a9o in Korea, it is now highly used and prospered by many online companies. Traditional studies concerning the electronic payment system are usually about the payment process itself, so they stressed the security or the robustness of the process. The study from the angle of behavioral science seldom exists. This article describes the phenomenon of technology adoption with a particular focus on telephone Payment service. The article identifies which characteristic of the telephone payment service affects to the user status (user, non-users). To do this, this article mainly used Roger's Technology Acceptance Model and some characteristics are added to the model. The most important perceptual characteristic that affects to the user status was not security, but ease of use-the telephone payment service had to enhance continuously for the competitive advantage over the other payment service. Observability and convenience are also noted as important.

Recently, there are rapid development of information and communication and rapid growth of e-business users. Therefore we try to solve security problem on the internet environment which charges from wire internet to wireless internet or wire/wireless internet. Since the wireless mobile environment is limited, researches such as small size, end-to-end and privacy security are performed by many people. Wireless e-business adopts credit card WPP protocol and AIP protocol proposed by ASPeCT. WAP, one of the protocol used by WPP has weakness of leaking out information from WG which conned wire and wireless communication. certification chain based AIP protocol requires a lot of computation time and user IDs are known to others. We propose a Micro-Payment protocol based on credit card. Our protocol use the encryption techniques of the public key with ID to ensure the secret of transaction in the step of session key generation. IDs are generated using ECC based Weil Paring. We also use the certification with hidden electronic sign to transmit the payment result. The proposed protocol solves the privacy protection and Non-repudiation p개blem. We solve not only the safety and efficiency problem but also independent of specific wireless platform. The protocol requires the certification organization attent the certification process of payment. Therefore, other domain provide also receive an efficient and safe service.
