摘要
大数据中的隐私保护问题是当前网络空间安全领域的一个研究热点,差分隐私保护作为严格且可证明的隐私保护定义,研究其在大数据环境下的应用现状能够为其后续的系统性应用等提供参考与指导。在系统分析差分隐私保护的相关概念与技术特性的基础上,通过对差分隐私保护技术在数据发布与分析、云计算与大数据计算、位置与轨迹服务及社交网络中的应用等进行综述,阐述了当前具有代表性的研究成果并分析了其存在的问题。研究表明,现有成果从差分隐私保护机理、噪声添加机制与位置、数据处理方式等方面对差分隐私保护应用进行了卓有成效的创新与探究,且相关成果在不同场景下实现了交叉应用。最后提出了差分隐私保护在大数据环境下进一步系统性应用还需要注意的四大问题。
The privacy protection in big data is a research hotspot in the field of cyberspace security.As a strict and provable definition of privacy protection,studying application status of differential privacy protection in big data environment can provide reference and guidance for its subsequent system applications.Based on the analysis of the related concepts and technical characteristics of differential privacy protection,the application of differential privacy protection technology was reviewed in data distribution and analysis,cloud computing and big data computing,location and trajectory services and social networks,which expounded the current representative research results and analyzed its existing problems.The research shows that the existing results have made effective innovation and exploration of differential privacy protection applications from the aspects of differential privacy protection mechanism,noise addition mechanism and location,and data processing methods,and the related results have been cross-applied in different scenarios.Finally,four major problems that need to be studied in the further systematic application of differential privacy protection in the big data environment are proposed.
