First, this topic is not related with Lineage. I just post it here, because this section looks to be alive in comparison with the proper section.

 

So, i have a java program that supposed to run offline. Do you have any ideas how to prevent users (i am going to sell them the program) and give it for free to their friends or w/e?

 

I know that everything can be cracked, but i don't care if somebody cracks it and give it for free. I want to prevent the simple copy from computer, paste it to another.

 

I know that this can be easily done with a server and an internet connection, but i want to avoid this option...

 

Shoot me with your ideas :)

make one program how can get Hwid from your customer pc

and after use the Hwid hard code on your program

You can check some p.c details like mac address in your base server or email or or or (you have to set it manually in your database ) the software will send the info everytime it run.... 

take care about the server connections. you cant prevent decompile so a connection that inserts data might be harmful. You cant prevent copying... lets say you can make it as 'less useful' unless it is register.. that way a copied software will be as a demo which might force them to buy it with giving the proper details on you

As i said my friend, i don't want to add any kind of internet connection in my program. (I know how to do it, i just don't want, because the program does everything offline) :P
