中文摘要: 作为物联网的典型应用,基于位置服务为人们生活提供便利的同时,其隐私泄漏问题也备受关注。时空关联性,是物联网区别于互联网的基本特征之一。本课题的研究内容可以概括为一个模型,三项技术:①充分考虑时空关联性的位置隐私保护模型,②位置查询中的隐私保护技术,③基于同态加密的位置隐私保护技术,④路网环境下的位置匿名技术。拟实现四个一的研究目标:①提出一个基于二分图的位置隐私保护模型,②提出一个基于PIR的位置盲查询协议,③提出一个欧式空间下的全同态加密算法,④提出一个基于互易匿名的路网位置隐私保护方案。课题的研究将为基于位置服务中隐私泄漏问题的解决提供理论依据和技术参考,为后续物联网隐私保护问题研究奠定基础。

英文摘要: As a typical application of the Internet of things,location based services provide convenience for people' life and also much attention has been paid to its privacy leakage problem.Spatial and temporal correlation is one of the basic characteristics of the Internet of things different from the Internet.This topic research content can be summarized a model and three technologies:(1)location privacy protection model of fully considering the correlation of spatial and temporal;(2)the location query of privacy protection techonlogy;(3)location privacy protection based on homomorphic encryption techonlogy;(4)the location of anonymous techonlogy in vehicle network.Planning to achieve four aims:(1)propose a model of location privacy protection based on binary chart;(2)propose a blind query scheme based on PIR;(3)propose a fully homomorphic encryption algorithm based on euclidean space;(4)propose a mutual anomymous method for vehicle network.The research will provide the theoretical basis and technica reference for privace leakage problem in location based services,and lay a foundation for subsequent content network privacy protection problem research.
