Preserving Privacy in Horizontally Partitioned Databases Using Hierarchical Model

Abstract

It is necessary to preserve information about the individuals in many organizations. So this paper is introduced to implement a distributed anonymization protocol to store data about the users on horizontally partitioned databases by providing secure query protocol to share data according to the specified query from the virtual databases. It concentrates on architecture querying heterogeneous distributed and also private databases.

Hierarchical Model for Preserving Privacy in Vertically Partitioned Distributed Databases

[7,8] and for vertically partitioned data the method proposed in [15] if the data stored at two sites. Here we are proposed a novel method to provide privacy to the data if the data is vertically partitioned and distributed over sites.
