As the Internet continues to have the commercial trade changed, the method of payment is one of critical components to conduct successful businesses through the internet. An electronic cash has all of the characteristics of a traditional commodity cash and ensures the security for all transactions. Accordingly an internet billing system based on the electronic cash is expected as the secure and efficient payment method for the future electronic commerces. The digital contents such as digital merchandise and services have the characteristic that both the delivery of merchandise and the payment of money can be accomplished on the same network and are helpful to idealize the design of the electronic commerce system. In this paper, Anonymity got to be possible by using a virtual ID in the process of payment, the payment steps were decreased by being processed on the same network, and the efficiency and the security were guaranteed by decreasing the frequency of the coding and communication.

The study evaluates India's technological advancement, which has created a range of opportunities for consumers to enter into digital payment space. Demonetization in India has forced all consumers and companies to embrace and create cashless digital payment platforms. The cashless economy scenario involves various factors for its adoption such as reach, availability and awareness. This study considers factors responsible for adopting new digital payment technologies in India's different regions across various consumers. The study includes descriptive statistics and variance analysis (ANOVA) to identify elements to achieve maximum satisfaction. The research collects data from 250 respondents living in India, experiencing digital payments and online transactions. The data is collected through a structured questionnaire and critically analyzed using statistical analysis. The data has been analyzed with no sectorial biases and tracked by creating real-time indications. The study uses various hypotheses after taking responses from a sample of respondents. Cronbach's Alpha analysis is also used to determine the validity and reliability of the data. The study illustrates the complete shift of consumer behavior from cash to a cashless economy. A certain number of factors are shown to directly influence the rate of such a shift toward digital transactions in India.

Intangible assets are the important tool which decides upon economic wealth and development of knowledge-information economy. We have to make effective use of intangible assets in order to assure surplus earnings, competitive superiority. The importance of intangible assets, especially patent right, may be properly understood only when their values are assessed adequately. It is very significant to appraise rationally patent right value from finance support, technology transaction, investment decision, M&A, legal proceedings, strategy and etc. Thus the purpose of this study is to evaluate the economic value of a patent right using DCF(Discounted-Cash Flow Method). This paper presents the basic model, related principles and standards of valuation, and then, case analysis of patent right valuation using DCF.

We propose an undeniable digital signature scheme which is practical since it has less computation and communication overhead than Chaum's one. We expect that this protocol be useful to develop secure systems such as electronic contract system, electronic mail system and electronic cash system.

With a rapid development of Information Telecommunication technique, network communication environment has been greatly improved. People come to feel more convinient to purchase products through Internet. Accordingly, various kinds of electronic payment systems have been developed and used. In this paper, we propose an algorithm which not only can associate the broker system with an electronic cash user, but also regenerate all amount of money previously paid using technique such as Meta-Message recovery and a RSA Blind Signature based on discrete logarithm problem.

This study analyzed and compared the accounting earnings quality after the adoption of K-IFRS, targeting the stock exchange-listed firms (KOSPI, KOSDAQ). The analysis first revealed that KOSPI had higher quality accruals, and better persistence and predictability of the reported earnings and cash flows, compared to KOSDAQ. Second, in both KOSPI and KOSDAQ, the predictability of future cash flow showed that the accounting earnings was better than the cash flows. Third, for the persistence and predictability of earnings associated with the degree of accruals, in KOSPI and KOSDAQ both all, groups with better accruals quality had greater persistence and predictability of earnings, and a better future cash flow predictability of accounting earnings.

The increase of electronic commerce leads to the increasing attention to the way customers pay and a large number of researches on payment system. Recently many researches on a system which provides anonymity in order to protect user\`s privacy have been carried out. And some potential problems from that system are being reviewed by anonymity control system. This thesis will include the following. First, I want to analyze the old scheme related to divisible and examine general ideas of anonymity control. Second, I propose a new blind signature in addition to KCDSA, the standard digital signature in Korea. The last one I want to propose is a new electronic cash system with the divisible for more efficient use of electronic cash which can control anonymity with the help of trustee.

Electronic cash is used as a payment tool for contents purchase in mobile electronic commerce environment. In order to protect customer`s privacy, we use blind signature. Blind signature has an anonymity property since it does not allow connection between customer`s ID and customer`s message. In this paper, we propose an blind signature scheme using elliptic curve algorithm based on Cap Diffie-Hellman Problem. Proposed scheme efficiently improved against existing blind signature scheme by reducing communication and computation time of the process.

최근의 급격한 전자상거래 시장의 확대는 21세기 기업의 생존전략으로 부각되고 있으며, 각 기업에서 적극적으로 추진되고 있다. 이러한 전자상거래가 활성화되기 위해서는 사이버 스페이스상에서 현금과 동일한 기능을 수행하는 화폐가 필요하다. 이렇게 전자상거래에서 통용 가능한 화폐를 디지털 화폐(Digital Cash)라고 하며, 전자상거래 구현을 위한 핵심 기술이 된다. 디지털 화폐에 관한 기술 개발 및 사용에 관한 검토는 이미 미국, 일본 등을 중심으로 적극적으로 추진되고 있으며, 상업적으로도 충분히 성공하는 사례가 제시되고 있다. 본 연구에서는 전자상거래 활성화를 위한 디지털 화폐의 활용에 관한 연구로, 현재 부산에서 성공적으로 수행되고 있는 디지털 화폐인 “하나로교통카드(HANARO Traffic Cand)”를 중심으로 디지털 화폐의 성공 가능성에 대하여 검토한다. 여기에서는 하나로교통카드 추진 배경 및 추진 경위, 하나로교통카드의 성공 요인 분석 등을 수행하여, 향후 디지털 화폐가 전자상거래에서 성공할 수 있는 방안에 대하여 검토한다.

IT 혁명으로 전자적인 활동이 전 사회의 중심 축으로 이루어지고, 또한 컴퓨터를 이용한 정보처리와 통신기술의의 눈부신 발달에 힘입어 기업의 Business에 커다란 변화를 초래하게 되었다. 특히, 인터넷이라는 환경하에서 전자상거래는 급속하게 성장하고 있으며, 기업은 전자상거래 모델을 앞다투어 개발하면서 새로운 E-Business 환경을 수용하고 있다. 또한 기업은 무역업무에 이러한 전자상거래를 도입하면서 국제간 거래의 활성화를 위해 노력하고 있지만, 국채간 사이버 무역이 안고 있는 여러 가지 애로점을 가지고 있다. 그 중에서 국제간 전자결제에 과한 문제이다. 인터넷을 이용한 무역업무를 실행시키고, 활성화하기 위한 하나의 결제방안을 제시해 보면 제3자에 의한 결제 시스템으로서 인터넷 서비스 제공업자, S/W 개발업체, 은행과 신용카드회사를 비롯한 금융기관 등은 결제시스템을 구축하는 방안이 강구될 수 있다. 또한 이 시스템에서는 다양한 판매자의 제품을 소개하고 일정 시간간격 또는 특정 구매자의 총누적 거래대금이 일정수준에 이를 때에 결제함으로써 신용카드를 지불수단으로 사용하는 경우에도 소액거래를 지원할 수 있다. 또한 전자결제제도가 성립되기 위해서는 전자자금거래의 규제를 위한 법 제도적인 측면의 정비가 시급하다. 따라서 각종 거래의 결제에 관한 법적관계는 물론 금융관련 법률을 기본으로 하여 새로운 접근방안을 마련해야 할 것이다. 이와 같은 사항들을 고려함으로써 사이버 환경의 활성화를 도모할 수 있다.
