Research On Flexible Payment Model In Emerging Electronic Commerce Environments

In the past ten years, the re-rise and rapid development of electronic commerce attracted extensive attention in both theoretical research and business. The environment of technology innovation that the emerging e-commerce based on and this environment’s profound influence for e-commerce bring us many research subjects, also introduced discussion for payment system construction.Payment issues are the core and key issues in e-commerce. Due to the payment system security requirements are higher than any other application system, and there are many theoretical and practical difficulties in the security issues, which directly or indirectly lead to the payment system construction has always been in a relatively closed and relatively rigid state. Therefore it bring many problems, for example, repeated construction, resources cannot be shared, services cannot meet customers’personalized requirements, and also cannot meet the demands of the Internet environment on all kinds of E-service. Research these issues and classify these issues into "flexibility of payment system", take these as the principal line of the research is the main characteristic of this paper.Flexibility of payment system issue covers the flexibility of the payment system architecture and the flexibility of the service. To solve this issue, we need to establish several important models according to the payment system principle and the development trend of new technology environment. These models not only cover and face payment system necessary composition and function, but also have new features that can specifically solve the problem of the flexible payment system.This research includes the following parts:firstly, the research background and scope of payment system flexibility in the emerging e-commerce environment are introduced and defined. After that, presents the-scientific problems and difficulties that involve in the construction of flexible payment system, and then analyzes and reviews the several important issues, namely payment process in the new environment,system architecture, PI transfer and the corresponding security, trust and the authentication problem. Based on these, puts forward flexible feature models according to the relevant scientific theory. At last, using these models, establishes a general mobile payment model based on "pre-trust" and "public-service-domain" for further instructions and verification of above-mentioned arguments.The main jobs and innovation points are follows. Firstly, a new four-phase payment process analytical model and payment component model taking payment instruction process as the main drive is established by applying design science theory and service oriented software engineering design theory.Secondly, a new flexible payment system architecture model——PSM, with public-service-domain as characteristics and multi-platform fusion as target is established.Thirdly, PI transfer model and hierarchical authentication model with the characteristics of "pre-trust" is established by integrated using information security theory, payment theory and information security technology.There are three parts in the third innovation point.The first part is the establishment of a "pre-trust" description framework and trust transfer model--TTM based on this framework. It lays theoretical foundation for PI transfer model and the authentication model.The second part is the establishment of a new "pre-trust" based PI transfer model——PITM, corresponding to the payment system service flexibility issue. It can span trust domain.The third part is the establishment of a new authentication model——PAM with one-way authentication and terminal simplified authentication as characteristics, to meet the demands of business entity trust and flexible PI transmission in open network environment.In addition, the refining of payment system flexibility issues, the classification of modern payment, system analysis of payment system authentication model,the building of general mobile payment model and so on in this paper also has the innovation significance.This paper has discussed payment system important issues in the process of establishing flexible payment models, try to raise new independent analysis and do achievements for payment system theory in the new environment. The main argument and views has certain contribution to the payment theory innovation, the trust theory innovation in Internet environment and information security theory innovation. Through theoretical research and case analysis, it proves the effectiveness of the proposed ideas.
