Abstract
Theft, distribution, and piracy of digital content (software, video, audio, e-books, any content of any kind that is digitally stored and distributed) is generally accomplished by copying it, if possible, or, if it is protected from being copied in any fashion, such piracy is based upon a number of reverse engineering techniques. Aside from the straightforward copying of unprotected content, all of these other methods require first an understanding of the protective mechanism(s) guarding the content, and finally an unauthorized modification of that protection in order to disable or subvert it. Methods which prevent a skilled individual from using reverse engineering tools and techniques to attain that level of understanding and/or prevent anyone from performing such modifications can offer significant advantages to content creators who wish to protect their products.
