Social networks are becoming popular, with people sharing information with their friends on social networking sites. On many of these sites, shared information can be read by all of the friends; however, not all information is suitable for mass distribution and access. Although people can form communities on some sites, this feature is not yet available on all sites. Additionally, it is inconvenient to set receivers for a message when the target community is large. One characteristic of social networks is that people who know each other tend to form densely connected clusters, and connections between clusters are relatively rare. Based on this feature, community-finding algorithms have been proposed to detect communities on social networks. However, it is difficult to apply community-finding algorithms to distributed social networks. In this paper, we propose a distributed privacy control protocol for distributed social networks. By selecting only a small portion of people from a community, our protocol can transmit information to the target community.

社交网络上的分散式私人信息共享协议

社交网络变得越来越流行，人们在社交网站上与朋友共享信息。在许多这样的站点上，所有朋友都可以阅读共享的信息。但是，并非所有信息都适合大规模分发和访问。尽管人们可以在某些站点上形成社区，但是此功能并非在所有站点上都可用。另外，当目标社区很大时，为消息设置接收者是不便的。社交网络的一个特征是，彼此认识的人倾向于形成紧密连接的集群，而集群之间的联系相对较少。基于此功能，提出了社区发现算法来检测社交网络上的社区。但是，很难将社区发现算法应用于分布式社交网络。在本文中，我们提出了用于分布式社交网络的分布式隐私控制协议。通过仅从社区中选择一小部分人，我们的协议可以将信息传输到目标社区。
