Unique ID for hardware devices

Hi,
I am doing a project to identify if any of the hardware (Mouse, Keyboard etc) is removed or replaced with another one. I tried Device ID and PNP Device ID using "ManagementObjectSearcher"
but it is not changing even if i replace a hardware, ie if i replace my mouse with another mouse the device ID and PNPDeviceID i am having is
the same as former.
What is this PNPDeviceID and DeviceID ?
Is there any unique ID with which i can identify a particular hardware ? and how to get it?

Thanks in advance

Thanks for your reply
Well, it has nothing to do with the software.
what i am trying to do is a way to identify, if someone replaces any hardware of my PC with another similar one.
Consider i am 20 PC's with similar hardware (Keyboard, mouse etc).
let PC-1 and PC-2 are having similar Keyboards of the same make and model. and if PC-1's Keyboard gets faulty
and someone replaces PC-1's keyboard with PC-2's keyboard i need a way to identify that keyboard does not
belong to PC-1.
So what i am trying to do is to save some unique Hardware ID(?) to the PC and compare it with the current hardware ID
every time the OS starts.
Is there any ID/Key for every hardware so that i can identify it

It depends on the hardware. There is nothing that will work for all hardware.

If you are attempting to develop a way to protect your software from improper use, there and hundreds of other developers trying to do the same thing.
