Secure cloud storage based on partitioning and cryptography

Abstract

Cloud-based storage is becoming a very good method for sharing any type of data in upcoming days. This method can reduce the burden of storing and retrieving data in local machines. But there exist many issues. The vendor itself can attack the user’s data and it can even delete or hide the data; if the user did not access the data for a long period of time. It also faces problems for synchronizing and uploading files and the vast range of internal and external threats for data integrity. Another problem is based on data security in cloud storage, where it does not have a proper encryption technique. Storing data in the cloud is financially good for long-term large scale data storage, although it does not fully offer guarantee on data integrity and availability. In this paper we are focusing the integrity of the data using a technique that divides the data into number of pieces and encrypting it by newly introduced method. Through this technique cloud ensures more security and integrity.
