Optimal and Secure Data Storage Technique for Cloud Based On Dual Encryption and Steganography Methods

Abstract

Cloud is a computing model that provides sharable resources, dynamically scalable infrastructure, data and storage to the users on demand. It has transformed the computing operations from a large systems to service oriented paradigms. This drift has made significant changes in design and delivery of services over heterogeneous requirements and environments. The changes in processing environment brings risk and challenges to the system. As cloud computing have become prevalent, organizations have started migrating their applications and sensitive data to the cloud, that is maintained by third party service providers. So the users are more concern about the risk of cloud computing if it is not properly secured and hence cryptographic methods are applied for secure data storage in the cloud. newlineSecurity has become an important issue in cloud computing, when applications run in public domain or beyond the firewall. Data security can be handled by encrypting data with cryptographic methods and applying strategy for data sharing. The advancement in computing technology makes cryptographic protocols infeasible because it can be cracked by enhanced hardware or code breaking algorithms newline
