How can sites and programs verify that you are the same person after hard disk reformat?
I know that they can trace your ip but beside that is there any other possibility? Is it like the car engines where every engine has a different number so the police knows whose car is that?
Shower thoughts :hihi:.
 
Solution
If you're talking about over a network some programs and sites can use your MAC address which is unique to your network hardware. Otherwise its dependent on your login, or the license numbers of your software.
