ABSTRACT:
The present invention is directed to methods and apparatus which may be used to help prevent electronic devices, including cell phones, from operating with software copied from (and only authorized for use by or on) another device. A further aspect is a device, including a cell phone, for example, that employs any of such methods and apparatus. Aspects of the present invention compare a program identifier (associated with software stored in a device) to a reference identifier for the device, so as to determine whether the software is authorized for use with that device. Some embodiments respond to the comparison substantially in hardware, so that the software being checked is less able to prevent the device from being disabled in the event that the program identifier and the reference identifier do not match one another.
