—In recent years, with the growth of the Internet,
the number of users of Online Social Networks (OSNs) has
increase. Users use these systems to communicate and share
information with each other. In order to protect the amount of
data that is being shared in these systems and to avoid security
and privacy issues, it is important to have an adequate Access
Control Model. Researchers have proposed different access
control models to satisfy users’ requirements and address the
security and privacy issues. This paper presents a discussion of
strength and weaknesses of the Social Graph Model and
Multiparty Access Control Model. In addition, we provide a
comparative analysis of the selected models based on the access
control requirements with the purpose of determining whether
the models fulfill or not the social requirements of the
