This paper shows the result of study on the detailed applicable procedure of software Escrow account applied for rolling stock. The customer as end-user requires software source code, related critical technical documents etc. about software based system of train for maintenance purpose through software modification and enhancement after completion of warranty period. Otherwise, it is not easy to keep up with the customer's requirement of demanding supplier's exclusive information because it is considered as intellectual property rights of supplier as software developer. Therefore, the main contractor(normally called as Car-builder) need to introduce software Escrow service in order to coordinate the different a standpoint between software developer and end-user. Software Escrow is a legal arrangement in which an software Escrow packages (software source code, software development tool, build process, proprietary information, copyright and etc.) is deposited into and Escrow account under the trust of a reliable third party (Escrow agent) depending on mutual agreement on Escrow contract condition as signing off Escrow agreement document. This paper deals with the study on the detailed procedure about the following general category of Escrow procedure and purpose to apply this specific procedure of Escrow into the future project onward.

As with the fast spread of internet uses in recent years, electronic commerce has evolved. The proliferation of electronic commerce has increased diverse forms of fraud cases since internet helps intended criminals remain anonymous. In absence of effective tools to warrant the reliability of parties offering products or services through electronic commerce, consumers have to absorb damages unfairly. Internet escrow service has been considered to be an option to establish reliability between buyers and sellers and to protect consumers from possible fraud cases. However, like other industries, fraudulent escrow services have appeared in internet. This study has been intended to analyze fraudulent internet escrow services and to propose an effective regulatory system of internet escrow services. To do that, this study benchmarked the regulation of the State of California, primarily focusing on the formation of escrow company, regulation of escrow business, and remedies for wrongdoing, so Korea can consider the adoption of similar systems.

인터넷을 기반으로 하는 B2B시장이 엄청난 속도로 증가추세를 드러내고 있는 가운데 국내 전자상거래 시장은 예상만큼의 기대치에 부응하지 못한 채 큰 발전을 보지 못하고 있는 상황이다. 이는 인터넷상에서의 효율적인 결제시스템의 부계와 전자상거래 시장의 특성인 신뢰성의 부재에 그 원인이 있다고 보아진다. 따라서 본 논문에서는 이러한 비대면의 전자적인 결제시스템에 따르는 신뢰성 문제해결을 위한 방안으로 Escrow계정을 이용하는 B2B 결제시스템을 제안하고자 한다. 본 연구에서 제안하는 Escrow Service시스템은 전자결제시스템의 걸림돌이었던 제품보증과 결제보증에 관한 문제를 데이터베이스로 구축하여 체계적이고 안정적인 방법으로 해결할 수 있는 EDI를 이용한 B2B ESCROW 결제서비스를 만드는 것이다. 구매기업과 판매기업간에 매매행위가 발생되면서 양사의 합의에 따른 Escrow사항들을 표준화된 데이터베이스 형식을 갖고 있는 EDI에 저장하고 거래 데이터베이스를 수행하면서 자동적인 EDI File Update를 통해 가장 실시간의 정보를 참조할 수 있도록 하는 것이다. 기존의 B2B 결제시스템에 있어서의 Escrow 기능이 계좌이체를 이용한 결제시스템에만 제한적으로 이용돼 왔었으며 또한 Escrow 시스템 수행이 수동적인 프로세스에 의해 움직여졌기 때문에 신뢰성과 이용도면에서 문제점이 있었다. 하지만 EDI를 이용한 Escrow시스템 구현은 프로세스의 자동화뿐만 아니라 계좌이체 및 기타 대출을 이용한 결제시스템에도 다양하게 적용할 수 있으며 또한 History관리가 가능하므로 전자상거래 결제시스템의 효율을 한층 더 높일 수 있을 것으로 기대된다.

This paper object is application of electronic Customers Relationship Management(e-CRM) for buyer This paper focuses on the possibility of the adaption of Escrow system in Local L/C opening and payment. The purposes of this study are to obtain efficiency and stability of Local L/C and to provide opportunity to accept trust of the transaction parties. The results of the study show that Escrow system is recommended when Local L/C opened, because Escrow system has the following merits: (1) Open system of internet can be used to Local L/C process. (2) Transaction process of Escrow system is very simple. (3) One stop transaction can be applied to all the process of local L/C.

개인의 사생활을 보호하는 것과 법집행기관의 합법적인 도청/복호화 요구 사이에서 균형을 맞출 수 있는 Key Escrow를 스마트 카드를 사용하는 공개키 암호 시스템에서 적용한다. 사용자의 비공개키는 권위있는 기관/키관리센타와의 상호작용 또는 사용자가 만든 비공개키를 escrow하는 신뢰받는 기관과의 상호작용에 의해 만들어지며 time warrant를 가져서 사용자가 세션키를 만드는 프로토콜을 따른다면 합법적인 도청/복호화의 경우 사용자의 비공개키는 공개되지 않는다.

Today as the scale of e-commerce constantly expands, the number and the amount of the consumer frauds are also increasing very rapidly, without sufficient levels of systematic support to prevent them. Internet Escrow service is one of the promising payment mechanisms, which guarantees secure electronic trades and payments. Especially, if the real-time product delivery information is available via RFID-based track-and-trace environment, the security and efficiency of the Internet Escrow services would be improved a lot. In this research, proposed a novel approach to integrate EPCglobal Network, which is a de-facto standard for RFID-based information network model, with Internet Escrow services. The proposed service model was implemented in the form of "Integrated Financial Platform", which supports the contracts among trading partners and the payment via Escrow services by being fully integrated with bank systems. Using the implemented EPCglobal Network-based Escrow service system, we would be able not only to shorten the money-flow cycle and to develop new kinds of loan services, but also to overcome the problems of existing Escrow services including the lack of product-related information and the delay of purchasing decisions.

Key escrow is a default property that is inherent in identity-based cryptography, where a curious private key generator (PKG) can derive a secret value shared by communicating entities in its domain. Therefore, a dishonest PKG can encrypt and decrypt ciphers or can carry out any attack on the communicating parties. Of course, the escrow property is not completely unwanted but is acceptable in other particular applications. On the other hand, in more civil applications, this key escrow property is undesirable and needs to be removed to provide maximum communication privacy. Therefore, this paper presents an escrow-free identity-based key agreement protocol that is also applicable even in a distinct PKG condition that does not use pairings. The proposed protocol has comparable computational and communicational performance to many other protocols with similar security attributes, of which their security is based on costly bilinear pairings. The protocol's notion was inspired by McCullagh et al. and Chen-Kudla, in regard to escrow-free and multi-PKG key agreement ideas. In particular, the scheme captures perfect forward secrecy and key compromise impersonation resilience, which were lacking in McCullagh et al.'s study, as well as all other desirable security attributes, such as known key secrecy, unknown key-share resilience and no-key control. The merit in the proposed protocol is the achievement of all required security requirements with a relatively lower computational overhead than many other protocols because it precludes pairings.

e-Trade Payment system has been transformed by quickly and effectively. The e-trade Payment system such as TradeCard System, Bolero Surf, Identrus Eleanor and e-Escrow and e-letter of Credit issued by SWIFT System enable partly sellers, buyers and service providers. This paper studies for SWIFT, Surf, TradeCard, Eleanor, e-Escrow as international trade payment, As reason following : The First, Bolero is a neutral secure platform enabling paperless trading between exporter, importer, and their logistics service and bank partners, insurance company. The Second, TradeCard is to manage procurement-to-payment worldwide, that is exporter, importer and connected partners, paperless platform. The Third, Identrus is the global leader in trusted identity solutions, recognized by global financial institutions, commercial organizations and bank partners around the world. The Forth, Escrow payment have effect to L/C issue and enter into electronic contracts in internet bank. Trader practice use Escrow Bank as the same bank that rules to Issuing Bank and Advising Bank and payment, acceptance. This paper of these electronic payment have studies new international trade payment to approach such as eUCP rules and TradeCard System, Surf of bolero, eleanor of Identrus, SWIFT.

We introduce the concept of a Identity Escrow Scheme, an application of key escrow ideas to solve the problem of authentication. In the Identity Escrow Scheme, the User escrows a own real identity to the Issuer and receives a Authentication Information. In authentication step, between the User to the Service Provider, the User only gives a Authentication Information to the Service Provider. Therefore, the Service Provider don't know a real identity of user's. However, when the User does unlawful actions, the Lawful Agent is called by the Service Provider, and his anonymity is revoked by cooperation of the Issuer and the Lawful Agent. We propose new Identity Escrow Schemes and analyze these.
