Providing Confidentiality and Integrity on Data Stored in Cloud Storage by Hash And Meta-Data Approach

Abstract

Cloud computing is a new computing model which is widely emerging technology in the recent years is adopted by most of the IT companies and other organizations. Cloud computing enables individuals and organizations to gain access to huge computing resources without capital investment. It does mean that users can utilize computing resources in pay per use fashion. The cost of storing large amount of data in the local storage is higher than cloud storage. However, the cloud environment is considered untrusted as it is accessed through Internet. Therefore people have security concerns on data stored in cloud environment. We proposed a new approach for securely storing our data in cloud and integrity checking mechanism by which we can check whether data integrity is preserved or not at the time of data retrieval.
