英文摘要	With the popularity of on-line social networks and the wide spread of smart phones, it is becoming more and more frequent and convenient for individuals to share resources, such as status, micro-blogs, blogs, photos, videos, and so on, with their friends over on-line social networks. Since on-line resources might be involved with several users at the same time, it is far from enough to protect the privacy of users with the simple group-based access control model (GBAC), in which only the privacy requirements of the resource owner is regarded. In order to provide augmented privacy protection for resource publication in on-line social networks, this paper proposes the concept of resource involvers and a new access model named Patronus, in which, the privacy requirements of the resource owner and its corresponding involvers are both taken into considerations. In Patronus, we employ a simplistic specification based on the format of "when-where-who-what" to describe a resource and the privacy requirements of an individual user. We implemented a prototype application based on Patronus for photo sharing on Android, and demonstrated its feasibility and effectiveness with several case studies.; Computer Science, Hardware & Architecture; Engineering, Electrical & Electronic; CPCI-S(ISTP); 0
