Online Auction Using Shill Bidding Prevention

Human cheating has been a barrier to establishing trust among e-commerce users, throughout the last two decades. In particular, in online auctions, since all the transactions occur among anonymous users, trust is difficult to establish and maintain. At present, shill bidding is the most severe and persistent form of cheating in online auctions, but still there are only a few or no established techniques for shill defense at run-time. Evaluating the strengths and weaknesses of existing approaches to combating shill bidding. Proposed system prevents shilling activities by monitoring bidding behavior and user history. IP tracking techniques are proposed to detect shilling. The system also takes necessary actions against shill activities at run-time. The experimental results demonstrate that, by prevention, detection and response mechanisms, the proposed auction system keeps the auction users secured from shill bidding and therefore establishes trust among online auction users. Sellers may find lower prices where their items are sold at auctions which potential bidders are avoiding. To prevent this shill bidding process, we developed such a system that makes the bidding process neat and clean.
