I have developed a software in JAVA in which I need to register user machine in my database.
Each user machine must be unique, if user login from another machine it should be detected.
For this I have use wmic commands to get ProcessorId and Baseboard SerialNumber.
I am appending baseboard serial number to processorId for more uniqueness.
But the problem is I am getting same ProcessorId+SerialNumber for 2 different machines.
For Eg : Machine 1 = abcd-123
Machine 2 = abcd-123
Also Baseboard serial number giving output like "N/A", "Unknown", "To be field by O.E.M".
I have thought of wmic csproduct get UUID which gives Mother board UUID,
but I am afraid of duplicity of the same, as many user has been already registered their machines and using the software.
Situation
User-1 already registered with machine text abcd-123 (processorId-basebord Sr No)
Now User-2 login to the system for very first time with different machine
having the same machine text i.e abcd-123
At the time of machine validation at server, User-2's machine shown as already registered so User-2 cannot proceed.
Please help me solving the problem.
For this I used user machine uuid by using wmic command.
wmic csproduct get uuid
This is unique for every motherboard.
IF UUID not available I used processorId + MobileNo
CURRENTLY THIS SOLVED MY PROBLEM.
