Method to secure data in the cloud while preserving summary statistics

Sanchita Barman and Bimal Roy

Abstract

In this paper we propose a method which will preserve sum- mary statistics of data organized in a two way table. We have shown that fully homomorphic encryption is a powerful solution. However it has a number of disadvantages which makes it impractical. We have proposed a Restricted homomorphic encryption method which uses Pailier encryp- tion and order preserving encryption. This new method can be used for practical purposes owing to it’s efficiency in terms of both speed and storage.
