Hi,

I need to create an application which will be writted on many CD-ROM (10.000 cd), each cd is same as other, there isn't any possibility to write a different file on each cd,

But I need to authenticate each cd without needing a manual entry (serial number...) by user.

So, I'm looking if it exist a SID on each CD, like the MAC address for network card and how getting it in C++.

Thanks all.
