    Unlinkability Support in a Decentralised, Multiple-identity Social Network
    (Open Identity Summit 2013, 2013) Thiel, Simon; Hermann, Fabian; Heupel, Marcel; Bourimi, Mohamed
    Providing support for unlinkability in a decentralized, multiple-identity social network is a complex task, which requires concepts and solutions on the technical as well as on the user-interface level. Reflecting these diverse levels of an application, this paper presents three scenarios to impede the linkability of multiple identities in decentralized social networking. Solutions cover a communication infrastructure which allows referencing to multiple identities; analysis of user content and sharing history to present linkability warnings; and user interface means allow for a privacy-ensuring management of partial identities. The di.me userware research prototype of the EU FP7 funded digital.me (di.me) is introduced to show the integration of the solutions accordingly.
