We learn that what people care about is how information is used, not who has access to it.
Saltzer and Schroeder, The Protection of Information in Computer Systems:
"The term 'privacy' denotes a socially defined ability of an individual (or organization) to determine whether, when, and to whom personal (or organizational) information is to be released."
Communications of the ACM 17, 7 (July 1974).
Goal: construct data base protocol that limits information access according to a formal definition of privacy
Privacy Definition: indistinguishability of the individual from the community
Method: measures epsilon-indistinguishability of a database query transcript

A privacy-safe zone: Privacy sensitive data mining establishes a boundary, which, if respected, assures no privacy risk to the individual.
Move from up-front enforcement barriers (DRM) -> open description of licensing terms (CC) with after-the-fact enforcement as needed
"Imagine a world where every online store sells DRM-free music encoded in open licensable formats. In such a world, any player can play music purchased from any store, and any store can sell music which is playable on all players. This is clearly the best alternative for consumers, and Apple would embrace it in a heartbeat. If the big four music companies would license Apple their music without the requirement that it be protected with a DRM, we would switch to selling only DRM-free music on our iTunes store. Every iPod ever made will play this DRM-free music," |
