Abstract: Online commercial activities are susceptible to high levels of fraud. Online sources of goods, including business-to-business resources, marketplace web sites, custom retail web sites, and the like may knowingly or unknowingly pass off counterfeit goods as genuine, sell overstock goods at low prices without production and commission costs, and solicit customers anonymously. In some embodiments of the present disclosure, electronic commerce sites are monitored using data metrics to track electronic retailer activities, monitor distribution volumes by source, and monitor pricing. Analysis of such items may be used to detect potentially fraudulent activity, and, based on manufacturer policy and threshold settings, may automatically report, notify, or take action against such illicit product sources.
