There aren't any one-to-one unique identifiers for a computer, sorry.  At
least, none that are reliable for what you ask.  This has been a
long-standing issue with hardware-based identification for encryption and
anti-piracy issues for years.  The simply problem is that existing IDs are
not generally constant values.  The most common identifiers used are
Ethernet card MAC addresses, CPU ID numbers, and HardDrive Serial Numbers.
The main problems with those, however, is that 1) ethernet MAC addresses and
HardDrive serial numbers are usually guaranteed to be unique only within a
particular manufacturer but not across the entire industry, and if the
ethernet card or harddrive is ever swapped out with a new one, you get new
values and you lose your original ID; and 2) CPU IDs are only supported on
newer CPUs within the last few years, and they can be (and usually are)
disabled by the user in the motherboard BIOS setup at system startup before
any software is ever run.
