piracy-preventing software on CD/DVD

[pouters]

hi guys!

we need your help..

we are currently pursuing a study on the concept of copy protection. the point is to be able to identify authenticated files and to copy-protect these files on a CD/DVD.

we are having a problem on how to identify files that are authentic and on what software/technology to use to create something that can copy-protect these files.

what we're asking is, can anyone suggest or post links suggesting technologies/softwares that would enable us to make this study doable?

thanks a lot!
