  5. Current Access Control • Sharing data/resources: • Shared Workspaces (BSCW,NetWeaver, SharePoint, etc.) • Social Networking Sites (Flickr, YouTube, del.icio.us, etc.) • Sharing needs access control • Current approaches: • Access control lists (email contacts) • Role-based access control (root, admin, user) • Social-based access control (friend, knows)

  6. Problems with Current Access Control • Problems with current approaches: • Coarse-grained: • Private vs. Public, share with ‘friends‘ • Fixed vocabulary, no flexibility • Too complex? • Result of current approaches: • Messaging, email • To move from messaging to sharing: • Social-awareness based access-control

  7. Real-Life Access control • We share resources based on social relationships we attribute to people • We may share our credit card details with our parents, but not with out friends. • We mentally annotate people, meaning of term may differ between people • parent, supervisor, friend, close friend, director, etc. • Real life model can be applied to online model • Annotation-Based Access Control • more natural and flexible

  8. Annotation-Based Access Control Model

  9. Demo Demos

  10. Object-centric to user-centric

  11. Future Work • Extend the model to include context-aware information, as opposed to user-defined. • Using the Open Social API, embed the uncle-share widget into social networking sites, such as MySpace or Xing. • Integrate Uncle-Share with social bookmarking systems, such as del.icio.us

  12. Annotate your friends • Name 5 of your firends and annotate them with 3 desired annotations • Do not use bald, fatso, ugly, beautiful, etc. • Use Collaboration-based term: researchWith, wirtePaperWith, etc. • Do you find it difficult or easy?

  13. Have a nice day! Thanks for your time and attention!
