Division of data in cloud environment for secure data storage

Cloud is the new trend in the evolution of the distributed systems. Cloud computing has emerged as a great backbone for better calculation, processing and message passing. Cloud storage can be accessed anytime, anywhere. User can store and retrieve their data remote cloud server without difficulty. The important concern is security. Privacy is even more important when it comes to cloud storage. The proposed work will help to achieve data privacy using division of data. The user data is encrypted using RSA and divided into multiple blocks and stored on different cloud servers. The Cloud Manager (CM) has the responsibility of storing the fragmented file in cloud server. In this proposed work the data cannot be processed by CM this increases the confidentiality of data. The division of data in the cloud environment for secure data storage achieves security as well as privacy to user data and enhances the performance by replication techniques.
