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 storedin 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.
