It has a characteristic of inexpensive cost, flexible method and quick movement. It has changed the method of transaction into an auction movement which allows common people to join in through the internet. It brings people a lot of convenience, at the same time comes about some problems. People start to focus on its fairness, honesty and publicity. In addition, its reliability and security are more concerned. It’s not only required a fairness and rationality on the design of system, but also keeps the information security and reliability when transferring to construct a platform of fairness and security. The system designs an auction system based on the mode of B/S, and proposes a flexible and reliable environment for trade service. The thesis put most words on design of module, data flow and realization of function, including client register, login, auction, competition, commodity researching, comment and credible stat for person on auction. The thesis also discusses how to build up an online auction system with Java, JavaScript, Jsp techniques and configure the SSL to ensure the secure transmission of sensitive information on the web server.
