Online Social Networks arguably are the most accepted service on the Web, today. Facebook alone has a claimed base of over 900 millons of users worldwide, google+ reached the mark of 10 million users in only 16 days after going public, and mobile social networks, like foursquare and Instagram, consistently gain momentum.
So far, Online Social Networks are self-contained, walled garden services, with a centralized omniscient provider that collects and shares PII selectively with customers and affiliates. The amount of information gathered about the users in the case of Web-based SNS has already been extensive -- but this information even consists of detailed location traces and preference information, given by the frequency of “check-ins” at visited establishments and comments annotated to them, in this new paradigm. The problems of security and privacy in such a surveilled, pervasive communication environment hence are becoming more and more crucial.
Moreover, observing the current trends, new communication systems are becoming even more dynamic, open and heterogeneous, enriched with social information. Future pervasive communication systems aim at supporting social and collaborative communications: the evolving topologies are expected to resemble the actual social networks of the communicating users and information on their characteristics can be a powerful aid for any network operation. Social networking services may be leveraged for providing extended information on contacts and their relations based on the containing online identities and the information they share. The emerging pervasive communication systems, which, with high probability will face lack of connectivity to central services more often than today, however, cannot rely on any a-priori knowledge, on any pre-established trust relationship nor on sophisticated integrated security infrastructures. They therefore are calling for new and dedicated security and trust mechanisms: raising entirely new privacy concerns they require new reflections on security and privacy problems such as trust establishment, cooperation enforcement or key management. The information leveraged, spanning social relations and personal opinions, consists of highly sensitive data at the same time, a fact that leads to a high risk of misuse or abuse.
The aim of SESOC 2013 hence is to encompass research advances in all areas of security, trust and privacy in pervasive communication systems with a special focus on the social aspects of the services.
