J. van den Hoven suggested to analyse privacy from the perspective of informational justice, whereby he referred to the concept of distributive justice presented by M. Walzer in “ Spheres of Justice ”. In “privacy as contextual integrity” Helen Nissenbaum did also point to Walzer’s approach of complex equality as well to van den Hoven’s concept. In this article I will analyse the challenges of applying Walzer’s concept to issues of informational privacy. I will also discuss the possibilities of framing (...) privacy from the point of the “art of separation” by looking at the intersection of information infrastructures and institutions. (shrink)
