  5. What does privacy mean to you?

  6. What is privacy? • Information privacy vs. decisional privacy • Information privacy concerns the collection, use, and disclosure of personal information • Decisional privacy concerns the freedom to make decisions about one's body and family • Public and Private Spheres • Distinction made in philosophical discourse • Private sphere • not bound by public rules • "deprived" of being heard and seen by others • Defining privacy as a right to • intimacy • secrecy • limited access to the self • control over information

  7. Westin “Privacy and Freedom” 1967 • "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" • Privacy is not an absolute

  8. Westin continued • Four states of privacy • solitude - individual separated form the group and freed form the observation of other persons • intimacy - individual is part of a small unit • anonymity - individual in public but still seeks and finds freedom from identification and surveillance • reserve - the creation of a psychological barrier against unwanted intrusion - holding back communication • Four functions of privacy for individuals in democratic society • personal autonomy • control when you go public about info • emotional release • be yourself • permissible deviations to social or institutional norms • self-evaluation • limited and protected communication

  9. Different views of privacy • Privacy as limited access to self • the extent to which we are known to others and the extent to which others have physical access to us • Privacy as control over information • not simply limiting what others know about you, but controlling it • this assumes individual autonomy, that you can control information in a meaningful way (not blind click through, for example)

  10. Multiple facets of privacy • How can posting personal information about myself on my web site result in a reduction of my privacy? How can it result in an increase in my privacy?

  11. Web privacy concerns • Data is often collected silently • Web allows large quantities of data to be collected inexpensively and unobtrusively • Data from multiple sources may be merged • Non-identifiable information can become identifiable when merged • Data collected for business purposes may be used in civil and criminal proceedings • Users given no meaningful choice • Few sites offer alternatives

  12. Privacy surveys find concerns • Increasingly people say they are concerned about online privacy (80-90% of US Net users) • Improved privacy protection is factor most likely to persuade non-Net users to go online • 27% of US Net users have abandoned online shopping carts due to privacy concerns • 64% of US Net users decided not to use a web site or make an online purchase due to privacy concerns • 34% of US Net users who do not buy online would buy online if they didn’t have privacy concerns

  13. Beyond concern • April 1999 Study: Beyond Concern:Understanding Net Users' Attitudes About Online Privacy by Cranor, Ackerman and Reagle (US panel results reported) http://www.research.att.com/projects/privacystudy/ • Internet users more likely to provide info when they are not identified • Some types of data more sensitive than others • Many factors important in decisions about information disclosure • Acceptance of persistent identifiers varies according to purpose • Internet users dislike automatic data transfer

  14. Few read privacy policies • 3% review online privacy policies carefully most of the time • Most likely to review policy before providing credit card info • Policies too time consuming to read and difficult to understand • 70% would prefer standard privacy policy format • Most interested in knowing about data sharing and how to get off marketing lists • People are more comfortable at sites that have privacy policies, even if they don’t read them
