Modeling an Electronic Commerce Protocol for a Trusted Banking

Abstract

E-commerce Protocols represent the allowed interactions among communicating components. Protocols are essential in electronic commerce to constrain the behaviors of autonomous entities. This paper proposed an e-commerce protocol that consists of two players: merchant and customer. The two e-commerce parties i.e., merchant and customer perhaps lie in far distance. The merchant has its bank and the customer also has its bank and the two banks (merchant bank and customer bank) are connected to a trusted bank. The trusted bank is an international government bank. The function of the trusted bank is to check the validity of the customer credit card and carry out the required money transfer. The bank protocol can detect duplicated, reused, or expired credit card. The proposed protocol guarantees fairness. That is by engaging in the protocol, no one in the e-commerce transaction i.e., merchant or customer, can gain advantages over the other players by misbehaving, misrepresenting or by prematurely aborting the protocol. The merchant site has been built as a web service model. This model is based on open standards and protocols: HTTP and XMLbased protocols including SOAP (Simple Object Access Protocol), WSDL (Web Service Description Language, and UDDI (Universal Description Discovery and Integration).
