A Bayesian Probit Online Model Framework for Auction Fraud Detection
Individual users are able to buy and sell a broad variety of goods and services worldwide on online auction and shopping websites, e.g. eBay.com and Taobao.com. However, attackers have also attempted to conduct fraudulent activities against honest parties for the purpose of illegitimate profit. On Internet auction sites, auction fraud mainly involves fraud attributable to the non-delivery of products purchased through an Internet auction site or the misrepresentation of a product advertised for sale. Malicious sellers may post a non existing item for bidding with false description to deceive the buyer concerning its true value, and request payments to be wired directly to them.
