Electronic and aerial surveillance, biometrics, closed circuit TV (CCTV), identity cards, radio frequency identification (RFID) codes, online security, encryption, the Google ‘right to be forgotten’ controversy, interception of email, the monitoring of employees, DNA, cloning, stem cell research, the ‘war on terror’—to mention only a few—all raise fundamental questions about privacy. Reports of the fragility of ‘privacy’ have, of course, been sounded for at least a century. In respect of the future of ‘privacy‘, there can be little doubt that the questions are changing before our eyes. And if, in the flat-footed domain of atoms, we have achieved only limited success in protecting individuals’ privacy, how much better the prospects in our binary universe? An account of some of the major forms of intrusion is provided, and controls over their use proposed.
