현재 사용되고 있는 ETCS(Electronic Toll Collection Services)는 충전식의 스마트 카드와 카드리더를 이용하여 필요한 정보를 읽음으로 인증 및 과금 결제를 처리하는 방식이다. 혀 방식은 스마트 카드 규격이 다양하여 사용자는 각 규격에 맞는 카드리더를 사용해야 한다. 게다가 충전식이기 때문에 매번 충전해야하는 불편함이 있다. 본 논문에서는 현 ETC(Electronic Toll Collection)시스템의 단점을 극복하고자 스마트 카드 대신 휴대폰과 WAP(Wireless Application Protocol) 서버를 사용하여 통행료 자동징수 시스템을 설계한다. 또한 휴대폰을 사용함으로써 ITS(Intelligent Transfer Service) 시스템과 별도로 지역적인 인증이 가능하여 인중절차를 간소화시킬 수 있으며, ITS 시스템의 부하를 줄일 수 있기 때문에 ETC시스템 처리속도 또한 증가시킬 수 있다.

A mobile phone has became as a payment tool in e-commerce and on-line banking areas. This trend of a payment system using various types of mobile devices is rapidly growing, especially in the Internet transaction and small-money payment. Hence, there will be a need to define its standard for secure and safe payment technology. In this thesis, we consider the service types of the current mobile payments and the authentication method, investigate the disadvantages, problems and their solutions for smart and secure payment. Also, we propose a novel authentication method which is easily adopted without modification and addition of the existed mobile hardware platform. Also, we present a simple implementation as a demonstration version. Based on virtual machine (VM) approach, the proposed model is to use a pseudo-random number which is confirmed by the VM in a user's mobile phone and then is sent to the authentication site. This is more secure and safe rather than use of a random number received by the previous SMS. For this payment operation, a user should register the serial number at the first step after downloading the VM software, by which can prevent the illegal payment use by a mobile copy-phone. Compared with the previous SMS approach, the proposed method can reduce the amount of packet size to 30% as well as the time. Therefore, the VM-based method is superior to the previous approaches in the viewpoint of security, packet size and transaction time.

In this paper, a smart bus system that automates public bus traffic payment by applying beacon and computer vision and provides bus route information, real-time location information, getting off alarm is proposed. By using the beacon to recognize busses near the stop and to board the bus to be boarded, this system automatically processes the payment when boarding by using the distance from the beacon and the information provided by the beacon and the face comparison. After the payment processing, the system provides the route information of the boarded bus and the real-time bus location information to the user, and when the user sets an alarm using these informations, the alarm is activated when the bus leaves the bus stop.

스마트폰의 확산으로 금융관련 결제는 어디서나 가능하게 되었기에 편리함이 증가하였다. 하지만, 위와 같은 편리함과 동시에 사용자의 단말이 해커의 공격에 취약하거나 분실할 경우 심각한 문제가 된다. 따라서, 위와 같은 부정행위가 있을 경우 이를 자동으로 탐지하는 시스템이 필요하다. 그러므로, 본 논문은 이러한 문제점을 고려하여 스마트폰을 이용한 금융업무를 처리할때 GPS정보를 적용한 이상금융거래탐지시스템(Fraud Detection System) 모델을 제안한다.

최근 얼굴인식 시장의 규모가 증가하고 있으며 모바일 결제, 디바이스 본인인증, 신분확인 및 출입 통제, 치안 등의 다양한 분야에 적용 되고 있다. 온라인 화상회의에서 출석하는데 번거로운 방식들이 사용되고 있으며 대규모 회의일 경우 인원파악에 어려움을 겪고 있다. 본 논문에서는 온라인 회의를 할 때 머신러닝을 이용하여 여러 수강자의 얼굴을 자동으로 인식하여 출석을 확인하는 출석시스템을 제안한다. 이후 사용자는 출석 시스템을 사용해 객관적인 데이터를 확보하게 된다.

So far the study of digital home has mainly been made up of the network technology and the sorority system, but the application to consider the discriminatory characteristics of the individual family members has been interested in comparison with the necessity. The system proposed in this study is to get the information of the internal users through the access-controlling system. The controller offers the discriminatory environment by activating the database of the internal users and controls the sub-system of the home-network. The suggested system can automatically offer the discriminatory environment among the family members by limiting TV programs or channels according to the users' age, by offering other internet environment according to the users, by putting restrictions on telephone numbers, or by restricting the settling right of the home-shopping companies.

This paper introduces a development of the auto sushi conveyer-belt payment system using UHF RFID dishes. In a sushi bar, instead of counting the number of the finished sushi dishes, sushi dishes with the UHF RFID have been used in the auto payment system to have accuracy and convenience. To recognize each dish, the UHF RFID tag has been designed, and auto-payment system has been developed. The UHF RFID tag under the dish has been recognized by an RFID reader, and the auto RFID payment system shows the total price of the finished dishes based on the color and number of dishes automatically. The performance of the developed UHF RFID tag and auto RFID payment system have been measured and verified.

In this paper, we propose a design of automated electronic sanction system for management of six sigma projects. The proposed system performs diverse operations such as registering and choosing enterprise-wide enhancement project, managing schedules of the project, verifying the validity of the project, and thus managing the whole life cycle of the project. Each six sigma project is stored in the database repository for facilitation of its later use. The proposed system has been effectively applied in a Korean company, and thus, through the proposed system, we expect the effects of innovation-related and enhancement-related activities which six sigma is fundamentally pursuing.
