Prevent Comparison Of The Online Pseudonym Offer Several Auction Mechanism

Auction is a long-lived trade mode. It has developed into an integrated system with its own sound mechanism and rules. Since the emergence of Electronic Commerce, Internet auctions have become an important component of it. With the development of computer, the Internet has provided an excellent infrastructure for executing auctions with more solders and sellers around the world with much cheaper cost. Online auction was embraced by people around the world. More and more new forms of auction have originated. Various studies on Internet auction, both theoretical and practical, have already been conducted. However, the online auction frauds have also come with it and have become the number one Internet fraud. The false-name bidding, an agent tries to profit from submitting a false-name bid under a fictitious name is a new type of cheating and is the most notorious one among them. In order to get rid of this type of fraud, many auction researchers have developed several new auction rules based on the traditional auction mode successfully. Because the focuses of these protocols are different, the validities differ too. This paper focuses on the differences between traditional forms of auctions and on-line forms of auction, and surveys those new auction protocols against false-name bidding and makes comparisons among them.One party to an exchange often knows something relevant to the transaction that the other party does not know. Such asymmetries of information are pervasive in economic activity. Some of the most exciting of the recent advances in microeconomics theory have been in the modeling of strategic behavior under asymmetric information. The study of auctions provides a way of approaching the question of price formation. A less fundamental but more practical reason for studying auctions is that auctions are of considerable pragmatical significance: The value of goods exchanged each year by auction is very huge. This fact in itself indicates that some theoretical study of auctions is warranted. The theoretical results in auction theory can explain the existence of certain trading institutions, and perhaps can even suggest improvements in the existing institutions.Auction is a dynamic pricing mechanism setting the price interactively based on predefined rules. The rules define the bidding process, the winner determination and the final price. The main parameters are opening bid, reserve price, duration and bid increment. In the study of auction, many results address the question: What is, from the point of view of the monopolist, the best form of selling mechanism to use in any particular set of circumstances? In this paper, we stress on traditional auction, on-line auction and how to prevent false-name bidding. We want to make auction understood and accepted by most people. The thesis is arranged as follows: First we give an overall look of the history of auction and introduce some basic knowledge about auction. In the second chapter, we first introduce the most common traditional auctions and then the comparison is made between the traditional auction forms. In the third chapter, the Internet auction are introduced and the unique forms of on-line auction are stressed. The strong points and weak points of each are also analyzed. In the forth chapter, after the examination of false-name bidding on GVA, several protocols against false-name bidding are introduced which are all proved strong in preventing false name. Later the applied environments of each protocol are listed and comparisons between them are made. Finally, we put forward the future of auction and the future study direction.
