As social networking services are getting more and more common, the need for privacy enhancing options, sophisticated identity management and anonymity emerges. In this paper the authors propose using role-based privacy as a response for these needs and introduce a novel model called nexus-identity network that is capable of describing services extended with such functionality. The concerned principles of role-based privacy are conferred in the paper and criteria are presented for anonymity. Conforming to the criteria the authors suggest storing the profiles of different identities in a tree hierarchy in a user-friendly manner. The analysis of anonymity shows that the network has a structure that can be easily interpreted similarly to graphs representing connections in regular social networks. The ease of profile management and network visualization are advantages of the nexus-identity model which can make a social networking service privacy and user-friendly as well.
