|Abstract:||Multimedia social networks(MMSNs) have provided a convenient way to share the multimedia contents such as images, videos, blogs, etc. online. However, due to various privacy concerns people often want to selectively share the contents with their friends, family, colleagues, etc. Access control mechanisms help in this situation by deciding the individual who can access the contents and who cannot. But traditional access control mechanisms may not scale well for fine grained access control requirements (e.g. different access control parameters for different parts in a picture) and large number of users in MMSNs. Thus, an efficient access control mechanism suitable for MMSNs is required. In this paper, we present an efficient bit-vector transform based access control mechanism suitable for MMSNs. Mathematical analysis and experimental results show the effectiveness of our proposed approach.|
