Along with the widespread use of mobile applications in our society the pervasive abundance of information raises questions about citizen's privacy, knowing that there is no privacy without security and that identity stealth is at the base of many cyber- crimes. This proposal presents my research in progress to design a dynamic system for context-aware mobile user privacy management. With the aim to address different gaps in the existing literature on which factor(s) affecting mobile user adoption of privacy management applications, the results indicate that (1) the characteristics of a dynamic privacy management system. (2) Using the semantic web technologies for designing a new privacy-friendly single sign-on application for privacy management. (3) An economically sustainable trade-off between the personal data disclosed and user's payoff by using a location-based mobile service in privacy management system.
