摘要：Digital Rights Management (DRM) systems will become an important distribution
channel for music and other content. Because of network effects and switching costs, DRM
systems incline to dominance. In the absence of competition, one might consider having third
party DRM providers offer parts of the system, in order to safeguard consumer interests. However,
this might break the security of the system. A possible solution is to have dominant content
providers compulsorily license their security technologies. This however, poses the question
what can be considered a security technology and what not. Are, for example, skip-thecommercial
buttons an information security technology or not? It should be content providers,
not technology providers, who should decide on this distinction.
