Privacy-Preserving Query based on Virtual Organization in Grid Database
Naijing Hu, Huan Zhou, Liang Zhao · 2008
As the development of the grid technology, it becomes more and more important in commerce application to preserve privacy and prevent information from being leaked when querying in a dynamic and heterogeneous grid database. This paper proposes a privacy-preserving query middleware PVOM (privacy-preserving visual organizations mediator) based on the security requirement of heterogeneous grid nodes, and present query algorithm based on privacy-preserving rule processed by PVOM, which can effectively preserve private information via detecting query and improve security in commercial environment application.
