saoriPrivacy is a pressing problem in today's digital world. Digital technology makes it possible to easily store, retrieve, and share personal information that in the past would have remained private; such technology creates a profound need for techniques and systems that will enable users to manage their privacy. We are exploring solutions to meet this need. We approach privacy management from a social perspective. We believe that privacy management is best performed in a social context; protecting one's privacy is not so much about what information is shared but about who that information is shared with and when it is shared. In this spirit, we are developing Saori, a privacy management system based on trust networks. Trust networks are derived from the trust found in social networks. Saori enables users to specify people that they trust and how much they trust them; Saori then weaves together users' trust to create a trust network(s). Saori enables two important behaviors. First, Saori enables users to share information via the links in a trust network. Second, users can grant access to any resource that they themselves have access to. (E.g. if Sarah grants Adam access to her calendar, Adam can grant Anna access to Sarah's calendar.) Thus Saori enables a user to offload consent to others in his trust network. We are currently integrating Saori into a number of existing computational tools so that we can evaluate it. |
