I have a DVD that I am trying to protect from being copied. The best solution I found was a hardware fingerprint id like Azsdk Hardware ID. I want to be able to wrap the autorun or the viewer.exe file with something like this, so when they put in the DVD, it will come up with their hardware ID. They email it to me and then I email them the unlock code to run. But I only want it to ask for their unlock code one time and then they are able to use it every time they put in the DVD, without asking for unlock. Is their anything like this available? Thanks
