Steganographic approach to ensure data storage security in cloud computing using huffman coding ( SAHC )

Abstract

Cloud computing offers the on demand computational infrastructure to the users which has the potential to decrease the huge cost to build IT based services. It can provide ubiquitous, convenient data storage facility. It is a significant issue as the whole data stored to a set of interconnected resource pools which are situated over different location of the world. Stored data can be accessed through virtual machines by unauthorized users. There are different types of security and privacy challenges that are required to analyze and take care. To ensure privacy and security of data in cloud computing, we proposed a new data hiding technique called Steganographic Approach using Huffman Coding (SAHC) which ensures data security in cloud computing during data-at- rest. Our objective is to prevent data access by unauthorized users from cloud storage. The main idea of this paper is to develop a steganographic technique to secure cloud data.
