Quova provides location services that map IP addresses to geographic locations. Currently, customers host a local Quova server to retrieve this mapping. Using Quova's new Web Service, customers can now use a simple script to access the data. Sophisticated e-retailers use Quova to detect possible fraud.  For example, some retailers check the distance between the actual and expected user location. They create rules in their Web applications to decline or review orders falling X miles or more away from the shipping or billing address. E-tailers report that orders coming from 500 miles or more away from the expected location have a higher probability of being fraudulent.
