c++ - Copy Protection Scheme -


i want create simple copy protection program, want program run original read-only optical disc (cd/dvd), question is:

  1. is there unique number each optical media check against program?
  2. is there simple way (or c++ snippets) programatically check whether program launched optical disc instead of writable disk?
  3. is there copy protection scheme know use, prefer end-user doesn't need input serial number, need internet access or use usb-dongle.

no. didn't specify operating system, know of no operating system in common use ties state of code in virtual memory medium launched from. once program running, whole concept of 'where launched from' not well-defined.

you tagged 'dongle'. requiring usb key, or particular media, possible, can't guarantee code launched it.
