The current Online Social Networks' infrastructure is composed by thousands of servers distributed across data-centers spread over several geographical locations. These servers store all the users' information (profile, contacts, contents, etc). Such an infrastructure incurs high operational and maintenance costs. Furthermore, this may threaten the scalability, the reliability, the availability and the privacy of the offered service. On the other hand this centralized approach gives to the OSN provider full control over a huge amount of valuable information. This information constitutes the basis of the OSN provider's business.
