Abstract
Subject matter described herein is directed to detecting unauthorized use, such as by a cloned mobile device, of wireless telecommunication services. Differences in location patterns of unauthorized and authorized mobile devices are leveraged to detect likely fraudulent uses. For example, a location-pattern entropy of an authorized mobile device is tracked. A change in the location-pattern entropy suggests an unauthorized use of the mobile device's account.
