Abstract: In our daily life, Online Social Networks (OSNs) become an important part. Thousands of million people that use OSN every day by friend recommendations, so OSN users social circle extend greatly. OSNs put forward attractive means for information sharing and digital social interactions, therefore increase a number of security and privacy issues. For privacy protecting scheme it prevents the revelation of identity of users but also the revelation of preferred features in users profile. An individual user can select features of his/her profiles that should not be disclosed to others. While OSNs allow users to restrict access to shared data, they currently do not provide any mechanism to enforce privacy concerns over data associated with multiple users. Usually social networking is represented as graphs, users are nodes and features are labels.
