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 1):
An electronic device, comprising:\n a chipset; a secure processing unit in the chipset; a memory in which is stored a first identifier that uniquely identifies the electronic device; a secure read-only memory (SROM) in which is stored a second identifier that uniquely identifies the chipset; an operating system configured to control:\n providing the first identifier and the second identifier in a communication to check correctness of the first identifier and the second identifier against pairings of identifiers in a registry of International Mobile Equipment Identity (IMEI) numbers, which are registered with GSMA; and \n obtaining access to a communication network in accordance with correctness of the first identifier and the second identifier.
