License Negotiation System for Mobile P2p Environment

Due to the swift development of mobile devices, the markets of mobile content business have grown rapidly during the recent years. This development has contributed to a fast introduction of mobile DRM technologies applied to the protection of content against illegal distribution enabled by short range messaging protocols and upcoming mobile peer-to-peer networking. Although the traditional peer-to-peer networking has strongly increased in popularity, the mobile solutions are still in an immature state. This diploma thesis studies the enabling technologies for content superdistribution in mobile peer-to-peer environment and focuses on the development of an intelligent license negotiation system for Series 60 mobile devices. The central idea behind the system is to provide a flexible and easy-to-use negotiation tool, which offers highly personalized licensing services and possibilities to race different content providers in a competitive bidding manner. The License Negotiation System is coupled with a DRM Platform, which provides good extension capabilities for an easy creation of new use rights. The implementation of the mobile client was carried out using Symbian C++ and the license server using Java SE. The implemented prototype turned out to work as designed, allowing content providers to form various service classes applied to the same content. The prototype was equipped with a negotiation logic, the purpose of which is to provide end-users with the best possible licenses matching their individual needs. Even a simple negotiation logic proved to offer competent results if the license database was large enough.
