随着移动通信和互联网技术的快速发展,社交网络逐渐成为人们开展社交活动的主流方式之一.为了维护并增强人际关系,用户乐于在社交网络中分享个人行为、心情等内容,但对这些内容的转发操作会为发布者带来隐私泄露的风险.为解决社交网络中的转发决策问题,在分析转发双方收益的基础上,提出一种基于博弈论的社交网络转发控制机制,能够有效阻止转发者的非诚信转发行为.在分析转发者与发布者选择不同博弈策略所得收益的基础上,结合转发操作的历史数据,计算转发者进行非诚信转发的概率,并通过与发布者设置的阈值进行比较,给出是否允许转发的最终决定.介绍了基于博弈论的转发控制流程及架构设计,对博弈双方收益进行定义和分析,给出博弈过程,通过实验验证所提机制能够支持发布者给出最佳转发决策,保障发布者的内容安全.%With the rapid development of mobile communication and internet technology, the social network has become one of the mainstream social means used in people's daily social life. To maintain and strengthen relationships with friends, users may share personal behavior and feelings through social networks. Forwarding these contents may result in privacy leakage. To help publishers make proper data forwarding decision, the benefits of both sides of the forwarding operation were analyzed, and a game theory based forwarding control method for social network was proposed which could effectively prevent dishonest data forwarding operation. By analyzing the benefits of both sides of forwarding op-eration and considering historical information, the probability of dishonest data forwarding operation was calculated and it was compared with the threshold set by publisher to make the forwarding decision. The procedure and framework of the game theory based forwarding control method was introduced. The benefits of both sides were defined and analyzed. The game play scenario was presented. Some results of experiments are shown to support that the method is effective and it can protect the security of content in social network.
