云环境数据发布服务中隐私保护相关技术研究

A Survey on Privacy Preserving for Micro Data Releasing in Cloud Computing Scenario

云计算环境下数据库服务应用系统中的隐私保护问题是影响组织是否选择相关服务的重要因素之一,本文界定了云计算数据库服务应用系统架构;分析了基于密码学理论实现访问控制方法的不足,探讨了云计算环境下支持多管理域合成的访问控制模型;研究了云计算环境数据动态变化场景下的用户隐私保护问题;介绍了经典数据发布模型,对比了发布数据效用度量方法。最后指出云计算环境数据发布服务中隐私保护的热点研究方向。

Data releasing service is one of the important issues in cloud computing platform. Privacy preserving on database application and service system is one of upmost factor which results if organization choices related such services in cloud computing environment. Therefore, it has important academic value and application prospect to study privacy preserving in cloud computing environment. Architecture of database application system in cloud scenario was defined; the ineKicient of AC merged with cryptog- raphy was analyzed; access control problem in multi - domain database application systems was discussed; fmthermore individual＇s privacy preserving issue in dynamic situation was studied; the classical privacy preserving model for data releasing situation was presented; data utility measurement methods for released data set were compared. Finally active research topics of database service in cloud computing environment were presented.
