针对社交网络(SNS)存在的隐私信息泄露问题,通过实例对我国社交网络隐私控制功能的可用性进行研究.从用户的角度,通过实验和访谈对人人网和朋友网的隐私控制功能进行可用性测试和对比分析,发现朋友网隐私控制功能的总体可用性比人人网稍好,但两者之间没有显著差异,均存在需要改进的不足之处.人人网需改进其隐私控制功能的集中式导航方式和集中的隐私设置界面；而朋友网则应改进其隐私控制功能的分散式导航方式和黑名单的设置功能.%Concerning the privacy disclosure in Social Networking Service (SNS), the usability of the privacy control in domestic SNS was studied. From the users' point of view, with the method of experiment and interview, usability testing and comparative analysis on the privacy control in Renren and Pengyou were handled. The result indicates that the privacy control in Pengyou is better than that in Renren, but there is no significant difference between the two sites. Both of them need some improvements. Renren needs to improve its centralized navigation of privacy control and the centralized privacy setting interface. Pengyou should improve its decentralized navigation of privacy control and the blacklist function.
