Privacy in Online Social Network (OSN) is a very important issue in users' data sharing. Users' often share their personal information in different forms such as public, private, or in groups for developing networks and/or sharing their views. OSN applications collect users information with their permission by offering social networking services. In some cases OSN uses users data for personalization, ads/campaigning, and service quality analysis purposes. In worst cases, OSN can share information with third parties for legal and/or business purposes. In a way, there are potential risk of privacy failure during data sharing might happen. This risks are mostly underestimated or ignored by the OSN users due tricky and hard to understand privacy policy information. In this paper, we put emphasis on understanding transparency as key ingredient for privacy policy development, and have proposed to integrate Transparency as key feature to the current privacy frameworks to ensures that users have understanding what kind of data they are sharing and how it is managed over the OSN.
