Abstract:
This disclosure is directed to enhanced security of electronic devices that use IMEI numbers. In addition to a first IMEI number that is created and tracked by an OEM, a manufacturer of chipsets for cell phones creates a similar, but unique second IMEI number that is burned into logic at the chip level of chipsets. The second IMEI number includes a serial number of the chipset to uniquely identify the chipset that is associated with the second IMEI. A combination of a first IMEI and a second IMEI is stored with a registrar. When a device attempts to access a network, a combination of the first IMEI and the second IMEI stored on the device are authenticated with the registrar. If the combination is valid, then the device is allowed to access the network. Otherwise, the device is deemed to be an unauthorized device and access to the network is denied.

Claim (Index 11):
The method as recited in  claim 6 , wherein the first identifier includes a serial number associated with the mobile device.
