Multimedia Security Technologies for Digital Rights ... (ISBN 0123694760)

covers all the major ideas in DRM:
With the ever increasing pervasiveness of the Internet, and greater storage on personal computers, the issue of protecting copyrighted material like songs and movies is a front burner. The editors have compiled a collection of papers that describe the state of the art in 2006 of Digital Rights Management. The chapters span a variety of ideas. Biometrics are one mooted solution. Digital watermarking is another. Along with multimedia encryption and authentication. And with the inevitable migration of film to digital film, the question arises of how to protect the latter. It is expected that the digital film will be sent via an electronic network to cinemas. Far quicker and cheaper than the current approach of mailing the analog film canisters. But anything that is digital runs the risk of unauthorised copying. Especially for new releases of films. So one chapter goes deeply into this conundrum.
