1. A method of maintaining a biographical digest of information stored in a radio frequency identity chip communicatively coupled to a motherboard of a mobile communication device, comprising:
determining, prior to activation of a wireless communication service for the mobile communication device, inception information about the inception of the mobile communication device by reading at least some information stored on a non-transitory memory of the mobile communication device; encoding the inception information prior to writing to the radio frequency identity chip of the mobile communication device, wherein encoding the inception information is performed at least partly by executing the biographical digest software layer stored in a non-transitory memory of the mobile communication device and executed by at least one processor of the mobile communication device; responsive to encoding the inception information, writing, by the biographical digest software layer, the inception information permanently into a static portion of the biographical digest of the radio frequency identity chip that is communicatively coupled to the motherboard of the mobile communication device, wherein writing the encoded inception information into the static portion is performed prior to permanently disabling write access by the biographical digest software layer; after the writing of the inception information into the static portion of the biographical digest, permanently disabling, by the biographical digest software layer, write access to the static portion of the biographical digest; in response to a triggering event, determining current information about the configuration of the mobile communication device by reading information stored inside the mobile communication device; in response to the triggering event, determining, on the mobile communication device, a lifecycle event of the mobile communication device that is associated with the current information, wherein the lifecycle event comprises at least one of: device inception, device activation, device branding, device rebranding, device return, device refurbish, or device termination; encoding the current information about the configuration of the mobile communication device and the lifecycle event to log into a dynamic portion of the biographical digest, wherein encoding the current information and lifecycle event is performed by the biographical digest software layer; and based on the encoding, writing the current information and the lifecycle event into the dynamic portion of the biographical digest of the radio frequency identity chip while write access to the static portion of the biographical digest is permanently disabled, wherein writing the encoded current information and lifecycle event into the dynamic portion is performed by the biographical digest software layer, wherein the inception information comprises at least three of: a federal communications commission (FCC) identity, a device model identity, an initial hardware version identity, a manufacturer identity, a country of manufacturing identity, a date of manufacture, an identity of a location of manufacture, an initial software version identity, an initial preferred roaming list (PRL) identity, an original stock keeping unit (SKU) number or identity, or an original universal product code (UPC), and wherein the current information comprises at least three of: a current software version identity, a current preferred roaming list identity, a current stock keeping unit identity or number, a current universal product code, a current device status, a communication subscription service activation date, a phone number, a current mobile equipment identity (MEID), a current international mobile station equipment identity, a current communication service provider identity, or a current communication service brand identity. |
