Abstract

In this paper we are concerned with the privacy, traceability and anonymity for content distribution and protection applications. We believe for many content protection applications, privacy friendly anonymous trust is needed. We argue broadcast encryption technologies have advantages over public key encryption systems in these applications. When coming to combat piracy, we provided some business scenarios where it is essential to offer traceability in order to protect the revenues drawn from the provided services. However, in some scenarios, privacy concern needs to be carefully addressed in order to have a viable business. We shed insights on different technologies that can be used to offer solutions in each category.
