Private attributes of Online Social Network (OSN) users can be inferred from other information (which is usually from users' friends and group information). To address this, social networking sites allow users to hide their friend lists and group lists, so that general public cannot see them. However, if a user doesn't make his friend list public, but his friends have public friend list where we can find him, we can do reverse lookup to extend the friend lists of the user. Furthermore, many social networks allow non-group members to list the members of public groups (e.g., Face book). These are strong violations of OSN users' privacy, and can be considered as privacy risks caused by the asymmetric configuration of settings in OSNs. In this paper we present the privacy risks due to the lack of symmetric configurations, which exist in most of the OSNs. To make our idea more clear, we propose a inference attack and show that it can be used to infer users' private information, even users already made their friend list private. We theoretically analyze the risk of proposed privacy issues, and evaluate the risk using experiments based on real-world OSN data. We show that it is not sufficient to only disable friend list and group list to guarantee privacy, and propose methods to mitigate these privacy issues. |
