ABSTRACT = {Nowadays, the scale of the user’s personal social network (personal network, a 
network of the user and their friends, where the user we call “center user”) is becoming 
larger and more complex. It is difficult to find a suitable way to manage them 
automatically. In order to solve this problem, we propose an access control model for 
social network to protect the privacy of the central users, which achieves the access 
control accurately and automatically. Based on the hybrid friend circle detection 
algorithm, we consider the aspects of direct judgment, indirect trust judgment and 
malicious users, a set of multi-angle control method which could be adapted to the social 
network environment is proposed. Finally, we propose the solution to the possible 
conflict of rights in the right control, and assign the rights reasonably in the case of 
guaranteeing the privacy of the users.},
