User-controlled Attribute Sharing in Virtual Community


  • NSF (TC)
  • Description:
    This project is focused on addressing the problems of online privacy in virtual communities such as social networking sites (SNSs). The question we are particularly interested in is "how can users control which attributes of theirs will be shared with other entities such as other users, 3rd-party applications, or service providers in virtual communities?" This question, so-called selective attribute release and sharing, has been partially addressed in the domain of digital identity management (permission-based attribute sharing, server-based approach) and in the domain of cryptography (selective attribute disclosure, credential-based approach). Our goal in this project is to develop fundamental techniques (both server- and credential-based) to attain user-controlled sharing of personal attributes in virtual community without compromising the user’s social intent and interaction.
