Group Centric Information Sharing Model for Social Networks

Social networking platforms like Facebook are immensely popular and help users to collaborate and share information in real time. However information sharing and privacy go hand in hand and It is very hard to define the term privacy infringement.

Amit Mahale and Pradeep Chinnam will review G-sis,a new group centric information sharing model [1] being developed by Ravi Sandhu and colleagues. While traditional approach to information sharing focus on attaching attributes and policies to objects as they are disseminated, the group-centric approach models bringing users and objects together in a group to facilitate sharing.

We will discuss and explore its relevance to improving privacy in social networks. We will also review the OWL-Time, an ontology for time [2] to implement temporal reasoning in our system We hope that the session leads to effective brainstorming and helps us identify relevant use cases towards our goal.
