SYSTEM AND METHOD OF DETECTING FRAUD IN THE PROVISION OF A DEAL FOR A SERVICE ON A MOBILE DEVICE

Abstract:

A system and method for detecting and accounting for the improper use of a deal code on a mobile device. When the user initially configures the mobile device, the third-party provider receives information from the mobile device that includes user information, mobile device information, a deal code associated with a third-party service, information about an application program preloaded on the mobile device associated with the service, and a hash value that is at least partially calculated based on the foregoing. The third-party service provider calculates a second hash value at least partially based on the received information and based on other predetermined information and compares the first hash value to the second hash value. Based on the comparison, the system determines if use of the deal code is improper and, if so, tracks the user and mobile device information to prevent improper use of the deal code.
