Abstract
New information and communication technologies and their integration extend possibilities for high-level human collaboration. Various groups of people can come together according to their private or business interests forming a virtual community through social networks. However, in addition to the positive effects of this technical breakthrough there are dangerous potential side effects using these high-level networked systems; the sensitive personal or business data can be misused. Therefore, privacy has an increasingly important role in social networks and is becoming a significant area related to business ethics taking into consideration the close connection between trust and privacy. The goal of this chapter is to discuss the role and relationships between trust and privacy in mobile (business) social networks and to introduce the possible types of privacy threats and countermeasures in case of online social networks. A short summary on future trends in mobile social networks is also presented.
