发明名称 LOCKING AND RESETTING LOCK KEY OF COMMUNICATION DEVICE
摘要 A device, such as a mobile phone, may include a memory to store a device-lock pass code. A processor in the device may compare the device-lock pass code stored in the memory to a device-lock pass code entered by a user to determine whether the entered device-lock pass code is correct. The processor may disallow use of the device when the entered device-lock pass code is not correct. The processor may reset the device-lock pass code stored in the memory when an entered unblock pass code is correct. Whether the unlock pass code is correct or not may be based on a comparison of the unblock pass code entered by the user to an unblock pass code associated with a removable identity module. In one embodiment, the memory in the device may include a boot module and an operating system. The memory may also include a memory area that stores the device-lock pass code. In one embodiment, the memory area is not accessible by the boot module, but may be accessed by the operating system.
