One of the major sources of inefficiency in supply-chain management is information asymmetry; i.e., information that is available to one or more organizations in the chain (e.g., manufacturer, retailer) is not available to others. There are several causes of information asymmetry, among them fear that a powerful buyer or supplier will take advantage of private information, that information will leak to a competitor, etc. We propose secure supply-chain collaboration (SSCC) protocols that enable supply-chain partners to cooperatively achieve desired system-wide goals without revealing the private information of any of the parties, even though the jointly computed decisions require the information of all the parties. Secure supply-chain collaboration has the potential to improve supply-chain management practice, and by removing a major inefficiency therein, improves productivity. We present specific SSCC protocols for two types of supply-chain interactions: capacity allocation, and e-auctions (electronic auctions). In the course of doing so, we design techniques that are of independent interest, and are likely to be useful in the design of future SSCC protocols.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

We argue that C2C e-commerce is an application domain that maps naturally onto the emergent field of P2P systems simply by its underlying interaction model of customers, i.e., peers. This offers the opportunity to take P2P systems beyond mere file sharing systems into interesting new application domains. The long-term goal would be to design a fully functional decentralized system which resembles eBay without eBay's dedicated, centralized infrastructure. Since security (authenticity, non-repudiation, trust, etc.) is key to any e-commerce infrastructure, our envisioned P2P e-commerce platform has to address this adequately. As the first step in this direction we present an approach for a completely decentralized P2P public key infrastructure (PKI) which can serve as the basis for higher-level security service. In contrast to other systems in this area, such as PGP which uses a \"Web of trust\" concept, we use a statistical approach which allows us to provide an analytical model with provable guarantees, and quantify the behavior and specific properties of the PKI. To justify our claims we provide a first-order analysis and discuss its resilience against various known threats and attack scenarios. In support of our belief that C2C E-commerce is one of the potential killer applications of the emerging structured P2P systems, we provide a layered model for P2P E-commerce, demonstrating the dependencies of various security related issues that can be built on top of a decentralized PKI.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

Likewise, it is critical in e-commerce applications to have the security service that generates, distributes, validates, and maintains the evidence of an electronic transaction. Quite of number of non-repudiation protocols have been proposed in distributed systems and evaluated based on some evaluation criteria. However, in the context of e-commerce, there are additional evaluation criteria to be considered: fairness to both the message sender and the message receiver with respective to their control over the completion of a transaction, the degree of trust on a third party, and existence dependency on a third-party for dispute settlement on a committed transaction. We identify the set of requirements for a message transfer protocol in e-commerce, and propose a new non-repudiation message transfer protocol that meets these additional criteria. Our protocol protects the confidentiality of message contents such that no unauthorized intermediary is able to see the contents. And, the protocol is superior to other protocols in that continuous existence of the third-party authority is not needed beyond the completion of a message transfer. Furthermore, with respect to the control over the commitment of a transaction, our protocol is fair to both the message sender and the receiver.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

A common shortcoming is the lack of customer service and marketing analysis tools in most e-commerce web sites. In order to overcome this problem, we have constructed an intelligent agent based on Case-Based Reasoning (CBR) and collaborative filtering, which we have included in our product recommendation system, called PCFinder. This system was four main characteristics. The first is applying novel methodologies based on CBR to an e-commerce application. We propose a heuristic to represent an Order-Based Similarity Measure, together with the method of weight modification and adaptation. The second is applying CBR and collaborative filtering techniques to make our intelligent agent more efficient and effective. We also apply clustering analysis techniques to assist our intelligent agent for grouping the customers according to their long-term profiles in order to analyze the user profiles (external attributes) and provide some suggestions of the items (internal attributes) of the product. The third is introducing a method for constructing product recommendation systems: from architecture to methodologies and from applied technologies to implementations. The last is providing a graphic-building wizard based on clustering analysis of the past purchasing history to the management staff for analyzing the marketing tendencies.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

Web services are based on a set of XML standards such as simple object access protocol (SOAP), universal description, discovery and integration (UDDI), and Web services description language (WSDL). The benefits of adopting Web services over traditional business-to-business applications include faster time to production, convergence of disparate business functionalities, a significant reduction in total cost of development, and easy to deploy business applications for trading partners. However, Web services architectures are built on an insecure, unmonitored, and shared environment, which is open to events such as security threats. Security concerns are the major barrier that prevents many business organizations from implementing or employing Web services. This paper discusses one of the classical security policies that deal with conflict of interest - the Chinese wall security policy. The paper then extends this concept into specifying and implementing conflict of interest assertions in the newly developed WS-Policy. WS-Policy is an XML representation that provides a grammar for expressing Web services policies, to allow service locators to have a common interpretation of security requirements in the matchmaking process. Further, this paper also describes a prototype Web service called \"CIRService\" for supporting conflict of interest assertions in matchmaking process. The paper will conclude with identification of further research into the area of identifying hierarchical structure and relationship among Web services, to be considered in the matchmaking process.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.
