We all know that Google stores huge amounts of information about everyone who uses its search tools, that Amazon can recommend new books to us based on our past purchases, and that the U.S. government engaged in many data-mining activities during the Bush administration to acquire information about us, including involving telecommunications companies in monitoring our phone calls (currently the subject of a bill in Congress). Control over access to our bodies and to special places, like our homes, has traditionally been the focus of concerns about privacy, but access to information about us is raising new challenges for those anxious to protect our privacy. In Adam Moore adds informational privacy to physical and spatial privacy as fundamental to developing a general theory of privacy that is well grounded morally and legally.
