Abstract: In cloud computing data storage is a significant issue because the entire data reside over a set of interconnected resource pools that enables the data to be accessed through virtual machines. It moves the application software’s and databases to the large data centers where the management of data is actually done. As the resource pools are situated over various corners of the world, the management of data and services may not be fully trustworthy. So, there are various issues that need to be addressed with respect to the Management of data, service of data, privacy of data, security of data etc. But the privacy and security of data is highly challenging. To ensure privacy and security of data-at- rest in cloud computing, we have proposed an effective and a novel approach to ensure data security in cloud computing by means of hiding data within images following is the concept of stenography. Even though after making using stenography mechanism we can achieve data security in cloud but we cannot assure integrity of stenographic file, which acts as a major drawback in cloud computing .To overcome this drawback we are proposing the data integrity technique to secure the data from vendor.
