Proof of Data Integrity Using No-SQL Database in Cloud Storage:A Survey

Cloud computing shares a pool of the application software, databases, and hardware to the centralized large data centers. When multiple users use the cloud service, the management of the data at the server side is difficult, so cloud services may not be trusted.  This paper introduces the problem of ensuring the integrity of data stored in cloud computing. To reduce the computational cost at user side during the integrity verification of their data, the many schemes introduce the notion of public verifiability. These schemes introduce one more network element which acts as an auditor on the behalf of the client.  The auditor preprocesses client's data and uploads it to the storage server and later verifies the integrity of that data. However, the challenge is to find out this verifier is itself trustable or not. For this, we propose a new scheme where the storage server as well as auditor also is assumed to be untrusted. Furthermore, we strengthen the performance of data operation to process user’s time series data by replacing traditional data warehouse solution into emerging big data technologies such as No-Sql databases. We also maintain multiple replica of data file to increase availability and reduce the data loss.
