Strengthen Privacy by Policy Generation & Secure Access on Content Sharing Sites

Abstract

Creating privacy controls for social networks that are both expressive and usable is a major challenge. Lack of user understanding of privacy settings can lead to unwanted disclosure of private information and, in some cases, to material harm. In light of these incidents, the need of tools to help users control access to their shared content is apparent. Toward addressing this need, we propose a Policy Hardening system to help users compose privacy settings for not only their images but securing each and every type of uploaded file. Dynamic groups are generated with particular policies of each group for secure access of files. We examine the role of social context, file content, and policies as possible indicators of users� privacy preferences. We propose a policy framework where user can upload all kind of files and provide different policies with different users.
