摘　　要：社交网络用户通过在社交网络中分享个人信息,提升自己在社交网络中的影响力,但个人信息被危险用户获得容易造成个人信息隐私泄漏。如何在保护用户隐私的前提下充分使用社交网络分享信息,是需要解决的问题。针对该问题提出了基于密度聚类的社交圈划分算法,在此基础上提出了基于社交圈划分的信息分享策略,并将其转化为0-1背包问题求解。最后,通过在Facebook数据集上实验对比,说明所提方法的有效性。Social-network users enhance their influence on social networks by sharing personal information in social networks, and however, the personal information is easily obtained by dangerous users. How to fully use social networks and share information while protecting users＇ privacy is a problem demanding prompt solution, and for this, a social circle partitioning algorithm based on density clustering is proposed. And aiming at the problem, the information sharing strategy based on social circle partitioning is suggested, and transformed into a 0-1 knapsack problem. Finally, experiment on the Facebook dataset indicates the effectiveness of the proposed method.
