US Patent 9218496 Dynamically updating privacy settings in a social network

A social network allows its members to regulate what data is accessible to other members using one or more privacy settings. A particular member of the social network can modify the one or privacy settings to grant or deny different users access to different data. When a member modifies a privacy setting, the social network determines which information pathways communicating data between members are affected. The affected information pathways are then modified responsive to the privacy setting to communicate data identified by the modified privacy setting and enforce the new privacy restrictions.
