Document-Oriented Database-Based Privacy Data Protection Architecture
Zhen Jiang, Yongqing Zheng, Yuliang Shi · 2013
NoSQL database has been popular in cloud storage and document-oriented database also has attracted much attention as a kind of NoSQL database. This paper introduces document-oriented database-based privacy data protection architecture. This architecture maintains the feature as scheme-free and nested document of document-oriented database, and protects tenants' privacy through split value and confused key. To prevent the attacker recombining the split value, we provide the theory of matching degree, and give related definition and algorithm to decrease the possibility of exposing tenants' privacy data. Finally the experiment proves that our architecture is practical and efficient.
