ABSTRACT:
Data in a portable electronic device is protected by using external and internal status detection means to determine if the device is misplaced, lost, or stolen. The device then takes, singly or in combination, one of several actions to protect the data on the device, including declaring its location to an owner or service provider, locking the device or specific functions of the device to disable all data retrieval functionality, erasing or overwriting all the stored data in the device or, where the data has been stored in the device in an encrypted format, destroying an internally-stored encryption key, thereby preventing unauthorized access to the encrypted data in the device.
