The functioning of Cloud Computing is significantly distressed with the aid of problems including that of statistics safety, integrity, theft, loss and presence of inflamed applications. These troubles are the important dangers to the consumer to transport their statistics to the cloud. we have analyzed various Substitution techniques to attain high level of security to cloud storage.
