A Modified Model for Cloud Data Security using Steganography

Abstract

Cloud is considered as a huge pool of resources and services from where the service or resource can be used whenever needed by paying the amount for the service being used. The basic goal of cloud architecture is to provide secure, appropriate, on-demand access to configurable computing resources pool over internet. The cloud computing idea relies on a most essential rule of “reusability of IT capabilities”. Cloud computing provides four fundamental deployment models. These models are the public, private, hybrid, and community cloud. Besides the providing benefits of cloud computing, also still there are some obstructions which should to be eliminated. These obstructions considered as challenges which can involve data protection, performance, control and reliability.
