在线社交应用中隐私驱动的访问控制研究

Research on Privacy-driven Access Control in Online Social Applications

随着互联网的发展,在线社交应用在人们的生活中越发显得重要。用户在自己的社交应用上发布消息促进与他人交流的同时也产生了隐私暴露的隐患。针对用户无法有效管理自己发布消息的问题,提出了一种保护隐私的访问控制机制:首先,标注模块对用户发布的消息自动的进行语义分析,然后访问控制模块对内容的敏感度进行评估,并根据用户的隐私需求对可能访问该消息的用户进行分类,最后对消息进行相应的处理并发送给请求者,该方法有效地保护了用户的隐私信息。

With the developing internet,online social applications are becoming more and more important in people's lives.Users can promote to communicate with others by publishing messages in their online social applications,but there are also hidden dangers of privacy exposure.A privacy preserving access control mechanism is proposed for the problem that users cannot manage their own messages effectively.Firstly,annotation module analyzes the semantics of the messages of users automatically.Next,access control module assesses the sensitiveness of their contents and classify the users who may access the message according to the user's privacy requirements.Finally,the messages are processed and different versions are sent to requesters who need to access the message.This method can protect the privacy information of users effectively.
