Secure and efficient data storage scheme for unstructured data in hybrid cloud environment

Enterprises are increasingly adopting cloud for their storage and computations due to various benefits like cost, availability, etc. It is important to ensure the security and privacy of the cloud to accelerate this adoption. Hybrid cloud is a solution to address these requirements of security and privacy. Hybrid cloud uses a mix of public, private, and managed cloud with a single access interface to the users. Security and privacy are addressed in hybrid cloud through data partitioning and data distribution depending on the sensitivity of the data and reliability of the cloud. Many solutions have been proposed for partitioning structured data, but there are very few works addressing the partitioning and distribution of unstructured data. With unstructured data, gaining importance in various applications like sentiment prediction, recommendation based on reviews, emails, etc. ensuring security and privacy of unstructured through partitioning and distribution has become highly relevant. In this work, a secure and efficient data storage scheme for unstructured data is proposed based on hybrid cloud architecture.
