Protecting digital music delivery and consumption using the OCCAMM project framework

Several standardisation initiatives recognised that content has value to both the user and the owner, and to ensure that this value is preserved it must be protected. One of those initiatives is called OPIMA, an initiative in the Industry Technical Agreement (ITA) program of the International Electro-technical Commission (IEC). OPIMA specification was implemented and validated in OCCAMM, an EC IST funded project. In OCCAMM a full-fledged system based on OPIMA, for secure distribution of multimedia materials was set-up and trial scenarios were established. Thus, this paper describes the usage case established by the OCCAMM project, in which digital music is traded in an Electronic Commerce Platform and distributed to final users in a secure, conditional and protected way. Music consumption is also controlled in the client through the enforcement of content and usage rules by a specific developed player.
