基于关系网络的个人信息保护模型研究

Personal Information Protecting Model Based on Relationship Network

针对社会网络(SNS)中个人信息保护的特殊问题,设计基于关系网络的个人信息保护模型,其关键在于将SNS中用户关系网络转换为量化的信任度网络,并据此决定用户的信息访问权限。相比现有SNS网络中的信息访问控制模型,此模型更加灵活精致,能较好地处理SNS中个人信息共享与保护之间的平衡,并通过研究此模型实现中的主要困难以及解决方案,探讨该模型的改进方向。

The paper proposes a personal information protecting model based on relationship network to meet the challenge of privacy proection faced by social network site（SNS） users. The key of the model is to transfer the relationship network to a quantized trust net- work, which will decide whether a user＇s information can be accessed by others. In addition, the paper discusses how to implement the model and the directions to improve it.
