  1. Philosophical definitions of privacy Lorrie Faith Cranor October 19, 2007

  2. Concept versus right • Privacy as concept • What is it • How and why it is valued • Privacy as right • How it is (or should be) protected • By law • By policy • By technology

  3. Hard to define “Privacy is a value so complex, so entangled in competing and contradictory dimensions, so engorged with various and distinct meanings, that I sometimes despair whether it can be usefully addressed at all.” Robert C. Post, Three Concepts of Privacy, 89 Geo. L.J. 2087 (2001).

  4. Some definitions from the academic literature • Personhood • Intimacy • Secrecy • Contextual integrity • Limited access to the self • Control over information

  5. Limited access to self • “the right to be let alone” • Samuel D. Warren and Louis D. Brandeis, The Right to Privacy, 4 Harv. L. Rev. 193 (1890) • “our concern over • our accessibility to others: the extent to which we are known to others, the extent to which others have physical access to us, and the extent to which we are the subject of others attention. • - Ruth Gavison, “Privacy and the Limits of the Law,” Yale Law Journal 89 (1980) “Being alone.” - Shane (age 4)

  6. Control over information “Privacy is the claim of individuals, groups or institutions to determine for themselves when, how, and to what extent information about them is communicated to others.” “…each individual is continually engaged in a personal adjustment process in which he balances the desire for privacy with the desire for disclosure and communication….” Alan Westin, Privacy and Freedom, 1967

  7. Realizing limited access and control • Limited access • Laws to prohibit or limit collection, disclosure, contact • Technology to facilitate anonymous transactions, minimize disclosure • Control • Laws to mandate choice (opt-in/opt-out) • Technology to facilitate informed consent, keep track of and enforce privacy preferences
