What the heck is "non-DRM?"

What the heck is "non-DRM?"

DRM is Digital Rights Management. It is a method to prevent theft or other unauthorized distribution of copyrighted intellectual property, like an eBook, movie, or audio recording. DRM protection prevents an unauthorized person from opening or playing the digital material. For eBooks, that means an unauthorized person can't open the book and read it. It would be really hard to provide our judges with the keys or other method to open DRM protected book. Again, our promise to you is that your work will not be distributed other than to be judged for this competition. After the scores are received, all copies will be discarded.
