Trust management and matchmaking system for multi-attribute reverse auctions

在所有互联网欺诈中占最大比例的在线拍卖欺诈正在上升，因为拍卖容易受到机会主义行为的影响。因此，拍卖被认为是信任关键系统。信任很难建立，因为交易发生在完全陌生的人之间。当前，拍卖行业面临着严重的欺诈行为，包括：虚标价、狙击屏蔽、拍卖人欺诈、拍卖人与竞标人之间的欺诈以及投标方尤其是落标方缺乏隐私等。先令欺诈和拍卖商欺诈是最难发现的欺诈类型。这些问题，在现有的拍卖行报告，使拍卖真的不公平和不可靠。为了增加对拍卖的信任并克服上述问题，我们希望开发一个可信赖的在线拍卖行，用于多属性反向拍卖，即在竞争卖家和多个属性来描述被拍卖产品的背景下。所有现有的关于拍卖信托管理的工作都涉及远期拍卖，即有竞争的买家，以及简单且不能在许多现实情况下使用的仅限价格的拍卖。

Online auction frauds, representing the largest part of all Internet frauds, are on the rise because auctions are vulnerable to opportunistic behaviors. Thus, auctions are considered trust-critical systems. Trust is difficult to establish because transactions occur among complete strangers. Nowadays auctions are facing serious frauds including: bid shilling, sniping and shielding, auctioneer cheating, auctioneer-bidder cheating and lack of privacy of submitted bids especially the losing ones. Shilling and auctioneer cheating are the hardest types of frauds to detect. These problems, reported in existing auction houses, make auctions really unfair and unreliable. To increase trust in auctions and overcome the problems listed above, we want to develop a trustworthy online auction house for multi-attribute reverse auctions, i.e. in the context of competing sellers and multiple attributes to describe the products being auctioned. All existing work on trust management for auctions concerns forward auctions, i.e. with competing buyers, and price-only auctions which are simple and cannot be used in many real-world situations.
