Requirements analysis for privacy in social networks

The rise and growth of social networks can be seen as empowering the user to change website's content by posting information using minimal technical knowledge. But, this empowerment has resulted in loads of sensitive data being let out unprotected in the public domain. To ensure user privacy, we need to understand privacy requirements relevant to social networks, per se. In this paper, we address this problem. We identify all the major stakeholders and their assets. We also look into the various aspects of user data that these stakeholders can be interested in. We then show how interests of various stakeholders can conflict and become threats for them. To counter these threats, we present a set of system requirements mapped to the respective privacy requirements.
