信息交换过程中的隐私保护技术研究

摘要

The privacy preservation problems in the process of information exchange have been summarized, ac-cording to the latest study and review related. Firstly, the different kinds of information service modes in pervasive networks, induce the essence of the information dissemination were introduced, and the risks of privacy information leakage during the information exchange were analyzed. Then the current research status of the information privacy awareness, privacy metric, self-adaptive adjustment scheme, privacy splitting and authorization extension were con-cluded. Finally, four research directions including the privacy awareness in the multi-source environment, sce-nario-aware privacy measurement, scenario defined privacy protection scheme, privacy splitting and authorization extension were proposed.%结合国内外相关最新研究趋势，对信息交换过程中的隐私保护问题进行了总结和展望。首先，介绍了泛在网络中不同类型信息服务模式，抽象信息传播的本质，并分析了主体在信息流转过程中的隐私泄露风险；其次，总结归纳了环境信息的隐私感知、度量、隐私保护方案自适应调整、隐私分割与延伸授权的研究现状；最后，提出了多源环境信息的隐私感知、场景自适应的隐私度量、场景定义的隐私保护方案、隐私分割和延伸授权等4个未来研究方向。
