We describe studies of preferences about information sharing aimed at identifying fundamental concerns with privacy and at understanding how people might abstract the details of sharing into higher-level classes of recipients and information that are treated similarly.

Such abstractions highlight the promise of developing expressive controls for sharing and privacy.<\/p>\n","protected":false},"excerpt":{"rendered":"
