Abstract

Many attempts to define privacy have been made since the publication of the seminal paper by Warren and Brandeis (Warren & Brandeis, 1890). Early definitions and theories of privacy had little to do with the concept of information and, when they did, only in an informal sense. With the advent of information technology, the question of a precise and universally acceptable definition of privacy became an urgent issue as legal and business problems regarding privacy started to accrue. In this paper, we propose a definition of privacy that is simple, yet strongly tied with the concepts of information and property. We show that privacy thus defined is not only useful in the context of the infosphere, but can also be successfully applied in its more traditional role as the ‘right to be let alone’.
