Abstract
Secure device data records (DDRs) are provided. In some embodiments, a system for secure DDRs includes a processor of a wireless communication device for wireless communication with a wireless network, in which the processor is configured with a secure execution environment, and in which the secure execution environment is configured to: monitor service usage of the wireless communication device with the wireless network; and generate a plurality of device data records of the monitored service usage of the wireless communication device with the wireless network, in which each device data record is associated with a unique sequence order identifier; and a memory coupled to the processor and configured to provide the processor with instructions. In some embodiments, the secure execution environment is located in an application processor, in a modem processor, and/or in a subscriber identity module (SIM).
