Due to the proliferation of using various online social media, individual users put their privacy at risk by posting and exchanging enormous amounts of messages or activities with other users. This causes a serious concern about leaking private information out to malevolent entities without users’ consent. This work proposes a reputation model in order to achieve efficient and effective privacy preservation in which a user’s reputation score can be used to set the level of privacy and accordingly to determine the level of visibility for all messages or activities posted by the users. We derive a user’s reputation based on both individual and relational characteristics in online social network environments. We demonstrate how the proposed reputation model can be used for automatic privacy assessment and accordingly visibility setting for messages / activities created by a user.
