| Summary: | 碩士 === 國立交通大學 === 資訊工程學系 === 86 === The rapid growth of Internet and World Wide Web (WWW) has
produced a maze of documents, databases, and programs. Almost
any information is available somewhere on the Net, but even
expert researchers waste a lot of time searching for the right
sources of information. Where to find desired information has
become a big problem. What we need is a more personalized tool
(agent) to help us travelling through the Web, searching
information, buying or selling things and making orders.
Because the SET (Secure Electronic Transactions) protocol
ensures the security of Electronic Shopping, Electronic Shopping
has become a new tide. How to find out information about
products quickly will become another important issue. In this
thesis, we propose a system architecture to develop agent
applications based on proxy server. Under this architecture,
neither do we need to change the standard protocols like HTTP
and HTML, nor do we need to modify existing components such as
web server and browsers. We implement an electronic shopping
agent to illustrate the system architecture.
