The present essay is organized into five main sections. We begin with a few preliminary remarks about "cloud computing," which are developed more fully in a later section. This is followed by a brief overview of the evolution of Helen Nissenbaum's framework of "privacy as contextual integrity." In particular, we examine Nissenbaum's "Decision Heuristic" model, described in her most recent work on privacy, to see how it enables the contextual-integrity framework to respond to privacy challenges posed by new and emerging (...) technologies. We then apply that heuristic device to questions surrounding one aspect of cloud computing -- viz., "cloud storage" technology. In particular, we focus on current practices affecting Google Docs as an instance of a cloud-storage system. (shrink)
