Patent attributes
A computer-implemented method and system for detecting fraud in electronic commerce traffic are disclosed. A global conversion rate is defined that represents activity related to a purchase made or proxy activity executed during electronic commerce traffic to a commercial website that is indicative of non-fraud activity. Subsets of the electronic commerce traffic to a commercial website are monitored for clusters of activity having a conversion rate that is lower than a global conversion rate by a threshold margin. A number of user-initiated input signals from an input device to navigate from each of one or more affiliate websites to the commercial website, and a number of conversions generated from each of the one or more affiliate websites, are registered by a computer for analysis.
