How to create DRM scheme to protect MP3 files with C++?

Question

Any ideas how I can create a DRM scheme to protect MP3 files using C++ or perhaps some other language?

Answer 1

The first thing to learn is that DRM systems only inconvenience the innocent consumers.

The content will have to be available in the clear at some point in order to be of any use. The determined person will intercept it at that point and make a unencumbered copy.

Answer 2

I recommend the UNIX command "rm file.mp3". This will ensure that nobody will listen to your music file.

Answer 3

You probably should first consider how many millions of dollars have already been invested in trying to protect music or video files.

And the number of music or video files that currently cannot be copied is zero.

Answer 4

I find the unlink() call quite effective in preventing unauthorized listening.
