Inhaltsangabe:Introduction: Recent years have witnessed the great popularity of online social networking services, in which millions of members publicly articulate mutual friend- ship relations. Social network services have become a major application in the internet. Correspondingly the number of provider such social net- work services has multiplied and accommodates estimated 272 million users worldwide (Universalmccann, 2008). The mass adoption of social networking websites points to an evolution in human social interaction. These sites let the user create an identity namely their profile, which they fill with personal information. These identities can then be searched and relationships among the users can be made.

In spite of these aspects there is an increasing demand for reusing and sharing the contact data to be able to manage the online friendships . To overcome the disadvantages of fragmented data central storage has to be established. In combination with exchange mechanisms it would make data reusable, which means all the social networks the user is part of could be synchronised. This is especially useful when entering a new network. It is like moving into a new city and already know some people. Inevitable for such a scenario is that the information of the social networks are portable and that the user can be uniquely identified. There are e orts to achieve this goal, but up to now only partial problems have been solved. An overall concept seems not possible at the moment due to [...]
