Constructing Virtual Commercial Website And Research Of Information Security

E-Commerce is the notion for the various activities of electric commerce performed by individuals or companies through computers and remote network. It developed very fast in the past 10 years. In the Web sites used for E-Commerce, text and 2D images are used widely for presenting products. The limitation for such presentation is that the effect has some difference to the real objects. Thus it will affect the decision-making of the consumers in E-Commerce. In this PhD dissertation, we will study the integration of virtual product presentation to shop.The fast development and great success of E-Commerce is based on the strong support of E-Commerce platform. Therefore, we have an overview of the E-Commerce platform .including E-Commerce model .electric trading model, paying system on Internet et al. We also discuss the E-Commerce framework integrating virtual product presentation. During the electric trading, the customers can view the product interactively, and the transaction is visible.In the study of techniques for establishing virtual product presentation for E-Commerce website based on JSP, we focus on the geometric model based product presentation and image-based product presentation. Geometric mode-based product presentation can provide multiple view of the product, and it is easy for the users to interact with it, while the model construction is time-consuming, Image-based method can only provide one view, but it only need one or several images. In geometric model-based product presentation, we design and implement an interactive virtual presentation system for home-used furniture on Internet. In image-based product presentation ,we design a new virtual product presentation shopping.Security problem is a key problem in E-Commerce, it contains two aspects: one is the security of electric trading; the other aspect is the copyright protection of the visual model of products in E-Commerce. In the thesis, we present a safe on-line transaction model exploiting the information hiding and digital watermarking, the transaction data embedded with identification watermarking istransmitted as ordinary multimedia data. The model can satisfy the requirement of secure transaction, such as safety, no-deny, credibility, confidence. In addition, the paper presents an algorithm of exploiting digital and digital watermarking. The experimentation result show that double entity authentication based on digital signature and digital watermarking is achieved. The security, creditability and authenticity are achieved.
