The popularity of Online Social Networks (OSN) is increasing tremendously. OSN enable people to connect with their friends as well as share information about their personal life. While most of the leading social platforms have primitives for providing privacy in the platform and the applications they are insufficient. There are some serious privacy problems that need to be resolved in existing OSN. There has to be a method to protect user-provided data in the profile as well as user-generated data by the OSN providers. Similarly a fully flexible and dynamic access control mechanism should exist to protect private data against attackers and unauthorized users.
