Enhanced Security in Cloud Using Data Partitioning Technique

Abstract

Cloud computing is now one of most popular technology in the computer science. Due to the invention of cloud, the perception of everyone has changes with infrastructure, deployment and development of software. The cloud provide various type of services like software as a service (SaaS),platform as a service (PaaS), and infrastructure as a service (IaaS).The sharing of data is the most important facility of the cloud. The emphasis of this paper is to provide a second layer of security to existing cloud storage solutions. The data is split into number of block and individual blocks are encrypt with the help of respective encryption keys within an image file and store the same on local hardware storage.
