Claim 0:
1. A method comprising:
receiving device data from a computing device, the device data including a plurality of parameters associated with the computing device;
identifying a parameter in the plurality of parameters for selecting a set of rules in a plurality of rules for determining a device identifier;
selecting, using the parameter, the set of rules in the plurality of rules, wherein the set of rules include logic for comparing at least one parameter in the plurality of parameters in the device data of the computing device to at least one parameter of previously received device data from multiple computing devices;
evaluating, using the logic, the set of rules in a sequential order until the device identifier is determined by comparing the at least one parameter in the device data of the computing device to the at least one parameter of the previously received device data;
determining a score for the computing device using the device identifier and the at least one parameter of the device data of the computing device; and
determining whether the computing device is a fraudulent computing device based on the score.
