The topic of surveillance is omnipresent: We are filmed in the subway, make private matters public on Facebook, and mini-drones will soon be so cheap that the curious can spy on their neighbors. All of this poses a challenge not only for politics but also for sociology. In the conversation documented in this volume, Zygmunt Bauman and David Lyon, the founder of Surveillance Studies, attempt to update Foucault's idea of the panopticon and Deleuze's considerations on the society of control to the latest technological advancements.
