What if the user wants to move their license to another system, or to a new machine? Can your licensing system allow this without making it easy for the user to run one license on both the old and new systems?.What if the parameter you lock to changes, say if the user upgrades their system by changing a piece of hardware? Will it break your system and need the user to request a new license from you?.Then the license won't work and the user will be inconvenienced. How do you obtain the system parameters? If you ask the user to provide them there is opportunity for human error, such as entering a '1' for an 'l' or a '0' for an 'O'.However, to avoid problems down the road, I'd suggest you think about the following:

The selection available will depend on the specific OS and programming language you use. The comment above is right - the MAC address is widely used for node-locking, but it is a poor choice as it is easily changed in OS.Ī more secure approach is to use a combination of hardware and software system parameters, such as hard disk ID, system name, user OS login name, CPU ID etc.
