Publisher's Synopsis
Virtual goods is one of the most important topics for research, development, and implementation. It has influence on technology, business, and politics. While the discussion on legal aspects is highly political, new technologies are coming up almost daily, such as incentive communication, PDP networks, watermarks, fingerprints, usage control languages, etc. Finally, some business models adopt these new technologies such as the PotatoSystem (one of the basic models for the Virtual Goods Workshop since 2003); others try to utilise DRM in a more effective way, such as the open Mobile alliance, ori tunes. This book presents the latest ideas in the field.
