CD Content Protect Application

I need a cutomized desktop software, that people should not be able to copy the content on my cd,I know someone that wrote a demo on it, but the problem is that his signature could not be removed from the demo. so I want my own application that once i burn the content on the CD with my cutomized signature(image logo). People should not be able to copy it from the cd, either by burning or virtual [login to view URL] should not be possible to copy. the content on the cd would be exe,pdf,any file. I dont want, the content on the CD to be able to copy on the person's hardrive
