Abstract
Millions of people worldwide are connected through networked digital infrastructure that grows increasingly sophisticated and contextually rich. A social network service is an online service, platform, or site that focuses on building and reflecting of social relations among people. A social network service essentially consists of a representation of each user called a profile, his/her social links, and a variety of additional services. Recent years have seen exceptional growth in the usage of online social networks and there are about 300 online social networks such as Facebook, Twitter, and MySpace, having more than half a billion registered users worldwide (Wikipedia, Social network service. http://en.wikipedia.org/wiki/Social_network_service. Accessed 25 Jan 2011, 2010). Users can often upload pictures of themselves to their profiles, post blog entries for others to read, search for other users with similar interests and compile and share lists of contacts. The information they share are not only viewed by the trusted users but also by the adversaries. This chapter is to encompass research studies in the areas of security, trust, and privacy applicable to social networks. The contributions relating to novel technologies and methodologies for securely building and managing social networks are discussed here. Also, the relevant secure applications as well as cross-cutting issues are narrated.
