I would prefer to combine 2 different attribute from system details like MAC
ADDR of any in-built interface with dmidecode output like system serial
number or system UUID.

//snippet from dmidecode
System Information
        Manufacturer: LENOVO
        Product Name: 2537CT1
        Version: ThinkPad T410
        Serial Number: R87AF8Y
        UUID: 81E34735-8450-CB11-973C-C064F0097285
