Recent public estimates indicate that by about 2005 the number of the Mobile Internet users will pass 500 million. In the future, mobile access is expected to be the dominant way of using the internet and its services. [1, 4] Widespread mobile use most likely requires entirely new types of services to be developed. The new services will probably pose new types of requirements for the underlying Internet infrastructure. New types of content, new types of business models, and new types of terminals require new types of protocols, middleware, and conventions to be adopted.[2] It is still unknown how the mobile technology industry will transform its business into me new era. If the successful Japanese I-mode is to be taken as an example, it will happen when technology and content providers cooperate providing a standard where the network infrastructure is in some sense closed and every transaction has its price. A digital rights management (DRM) solution is needed to implement this content distribution architecture, which should be capable of handling rights to different types of content and complex charging mechanisms. [3] This paper aims at giving an overview on how the openness of the future Internet affects digital rights management.
